Talking About Biodynamics at Troon Vineyard

Biodynamic consultant Andrew Beedy and I had a great conversation about Biodynamic farming with Chris Sawyer on The Varietal Show!

The Pace of Knowing

“The pace of knowing on our part does not alter how creation works,” Michael Phillips in Mycorrhizal Planet

A recent article in the New York Times revealed that the Moon has a tail, much like a comet. “It almost seems like a magical thing,” said one of the astronomers. For a few days each month, like clockwork, a stream of sodium particles from the Moon wraps around the earth’s atmosphere. That tail is dusting the Earth with sodium. 

“But even invisible, knowing the Earth has a meteor-fueled moonbeam is satisfying enough — a reminder of the Moon’s dynamism.” Says Dr. James O’Donoghue, a planetary scientist, “I think we definitely take it for granted.”

While we can’t sense the passage of this beam around the Earth, It does not mean that other beings on the planet cannot. There is much we still do not understand about the cycles of the natural world. Nature’s smallest beings sense many things that are invisible to us. 

The more you pursue the science of regenerative agriculture, the more connections to biodynamic practices you discover. That is not to say the reasoning behind those practices are the same, but the practices themselves often closely align. 

“As the second most abundant element in the Earth’s crust and the soil, silica has been largely ignored by agronomists. Silica is crucial, however, as it provides plant defense against pests and fungal/bacterial disease and reduces plant stress. It is a cell-strengthener and an activator for many plant functions,” says Nicole Masters in her thought-provoking book For the Love of Soil.

“Soil application of colloidal silicon increased plant-available Si, but only foliar application increased the total silicon concentrations in leaves, yield, and cluster weight. Moreover, the wine produced from the silica-treated grapes were ranked better in sensory evaluations,” states the Czech Academy of Agricultural Sciences in the article Effects of silicon amendments on grapevine, soil, and wine

One of the biodynamic preparations that raises most eyebrows (although all of them do for some) is BD 501 — the silica mentioned above. Silica is now routinely applied in many crops throughout the world. I’m sure most of the silica applied in agriculture is not buried in a cow horn first. Is the biodynamic method better than simply applying silica? I don’t know. However, I do know that silica prepared in the biodynamic way does make a difference in the vineyard. Our neighbors and good friends Barbara and Bill Steele at Cowhorn Vineyard have refined this practice over almost two decades of biodynamic farming. They use multiple precisely timed applications of BD 501 to encourage their Rhône varieties to reach higher brix levels in their cool Applegate Valley site. The proof is found in their exceptional wines. 

While Rudolf Steiner got a lot of the “hows” and “whats” right in his lectures, the “whys” are clearly not always on the mark. Steiner saw cow horns as kinds of radio telescopes that captured cosmic energies and transferred them to their contents. He was clearly right about silica, but cosmic energies? I think terms like “energies” and “forces” are just names for things we don’t understand. There was a lot that was not understood about plant biology in the 1920s, when Steiner gave his lectures (he died a year after giving them), while we understand much more today, there is still much that is not known. 

Having made our own BD 500 and BD 501 at Troon Vineyard for several years now we’ve had our own experience with burying cow horns to make these preparations. One thing is clear — the cow horns work in the sense that the final product is ideal for the job. Do they work because they are the perfect size and material or because of those cosmic forces? I admit there is a little bit of the “if it’s not broke don’t fix it” mentality here. Will other containers work just as well? I look forward to others doing that research and letting me know. I’d be happy to change, but I would prefer to not be the one experimenting as my immediate concerns are getting great fruit quality in the vintage at hand. 

There is one cosmic energy that no one doubts — the Sun. Apparently, now the Moon can join that club. Not only does the Moon’s gravity gives us tides, but once a month the Earth is enveloped in its tail. Like a timepiece, the moon showers us not with mysterious cosmic energies, but a dusting of sodium. We can’t see it or feel it, but to the microbiology in the soil and plants, it may sound like Big Ben striking noon. 

There are so many aspects of biodynamics that are now entering the mainstream of agricultural science. Composting at lower temperatures to increase fungal and bacterial populations. State-of-the-art compost tea brewers aerate compost tea overnight, which also builds those populations, as does the biodynamic practice of dynamizing. Even farming by the Moon may have to be reevaluated. It was obvious to many of us that biodynamics worked. All you had to do was to taste the wines. While we knew it worked, we were not very comfortable with the “whys” as presented by Steiner. Slowly, but surely those gaps are being filled by the new science of regenerative agriculture. 

It is my hope that the new Regenerative Organic Alliance and Certification will bridge those gaps. It embraces both USDA Organic and Demeter Biodynamic Certification, but fully incorporates the rapidly advancing science and knowledge that is happening in agriculture today. 

It’s not magical forces, but the Sun, soil, Moondust, mycorrhizal fungi, and manure that make agriculture work. As Michael Phillips wrote, “Nature does what needs to be done if we let her.”

Humble — something we should be when it comes to the natural systems. There is so much we do not know. Nature works, that’s truly magical.

Interview on the Organic Wine Podcast

I spent a entertaining hour discussing biodynamics regenerative agriculture at Troon Vineyard and life in Oregon’s Applegate Valley with Adam Huss on his Organic Wine Podcast.

“Today we take a trip to the country to meet Craig Camp, the General Manager of Troon Vineyard in the Applegate Valley AVA of Southwest Oregon. Troon is a certified organic and biodynamic winery and estate vineyard that focuses on blends made from the grapes of Southern France, which seem to do extremely well in this northern area with a hot Mediterranean climate.

Craig was brought in to regenerate every aspect of Troon, and we had a very enjoyable conversation about everything that is happening there that he has helped implement. From soil testing and replanting and staff education to sheep dogs to organic vegetable gardens and more, even from the outside it’s exciting to hear about what he’s doing, and you can hear the excitement in the way he talks about it.

Craig has a personal story in regards to wine that I can relate to as well. He fell in love with wine far away from where it was grown, and over the course of his life and several career changes, he worked backwards toward an understanding of how the finest wine begins in a healthy, probiotic soil.”

Listen to My Interview on The Organic Wine Podcast

Dirt is Not Terroir

It was the early eighties, and I was yet again rereading several chapters of Edmund Penning-Rowsell’s tome The Wines of Bordeaux. I had just spent the day tasting in Graves and Sauternes from the tank and barrel with renowned French wine exporter Christopher Cannan. Now it was night, and I was getter ready for bed in a small, dimly lit guest room above the offices of his company Europvin in the city of Bordeaux. We were visiting the Chateaux he worked with throughout all the appellations of Bordeaux. Each night before sleep I would review the appellations we had visited that day and those we would visit the next. That week long visit to Bordeaux was followed by a week in Burgundy with Becky Wasserman and my nightly reading changed to Burgundy, then a brand-new book authored by Anthony Hanson.

The next year I made a similar trip to Italy. Setting off with famed Italian wine exporter Neil Empson, we visited almost every wine area of Italy to taste at nearly every estate in his extensive portfolio on a three-week tasting marathon. In my bag was a well-worn copy of Burton Anderson’s Vino, the Italian wine bible of the day. My reading pattern was the same as when I was in France, reviewing each night on where we had been and cramming on where we were headed the next day.

I have been lucky over my career to have made multiple such trips to France, Italy, Spain, Germany and Australia. Top that off with many, many trips through the wine regions of California, Oregon and Washington. On each trip I would devour the current wine literature of each region before, during and after each visit.

I was obsessed with wine books and literally would buy and read whatever came out each year and my bookshelves overflowed with dog-eared, wine-stained volumes. This was the era of my life when I was a wine importer and distributor based in Chicago. Then, two decades ago, I made the transition from wine distribution to wine production and my reading list began to change. Slowly but surely instead of reading books about wine, I began reading books about farming. I recently realized this when I noticed that the last five books I’ve read all have the word soil in the title.

Even though my reading materials have changed, I am still as obsessed by the concept of terroir as I was decades ago in that small room in Bordeaux. However, what that means to me has changed significantly.

Those books presented terroir as something magical. That each site is a unique expression of the soil where it was grown. Then you actually start to grow wine and a new reality presents itself.

Take Oregon and Burgundy for example. In the Willamette Valley the soils are volcanic or sedimentary acidic soils. Summers are almost desert-like with no rain for months. Burgundies are grown on alkaline limestone soils and there is rain throughout the growing season. There’s not much in common here except one thing — outstanding pinot noir. Time after time experienced professional tasters find it difficult to tell which wine is Willamette Valley and which is Burgundy.

Burgundy and the Willamette Valley are not alone in this for the same experts can confuse California and Washington Cabernet with Bordeaux and California Coast and Oregon Syrah with Rhône wines. Each of these areas are very different from each other. How it is possible that all can produce wines whose provenance confuses the experts?

The reason is we have always made the cornerstone of terroir the type of soil the vine grows in — limestone, volcanic, granitic, sedimentary and so on. But it turns out that it’s not the exact type of soil that matters as much as the life in the soil itself. It has been this realization that changed my reading from wine books to soil books.

Terroir is not an expression of inert dirt, it is the individual expression of living soil and how a healthy plant intertwines with that soil. Dirt is not always soil. Soil is a system teeming with life.

Obviously, there are distinct sites. Terroir is a combination of many things. Climate and mesoclimate are critical, then there is the human element — row spacing, trellising and picking the right variety for the right place. For example, planting cabernet in a cool climate and pinot in a warm climate is not a great idea. But it takes grapes grown on healthy vines on living soils to make an expressive wine with a distinct character.

What makes for a living soil? Here is where you find the reason that biodynamic wines have a unique liveliness that stands out. Sustainable agriculture is not enough. That only means that you are killing the life in your soils more slowly than industrial agriculture. It is only with regenerative agriculture that you can build soil that creates distinctive, individualistic wines.

Plants and the microbiology in the soil have a complex symbiotic relationship. The plant takes a large percentage of the carbohydrates it produces through photosynthesis and pushes this exudate out through its roots to attract the microbes it needs to extract nutrition from the soil. It can change the mix of exudates depending on its requirements at the moment. A healthy plant decides the microbiology in the soil by the mix of gourmet microbe treats it sends out through its roots. That microbiology then returns the favor by processing the nutrients in the soil into a form the plant can utilize. The healthier the plant, the healthier that microbiology becomes. The healthier that microbiology becomes, the healthier the plant becomes. Not a bad system.

Then we come in and screw it up. The application of pesticides, fungicides and fertilizers destroys nature’s well-tuned system. In that system is to be found what makes a vineyard unique. It is an essential element of what we call terroir. The grapes that make distinctive wines come from vines in vineyards where nature’s system is humming along. Our job as farmers is to assist the plant and soil in regenerating that balance year after year. This is vital when you have a perennial crop like vines that do not lend themselves to crop rotation.

Coming back to the Willamette Valley and Burgundy comparison, perhaps their shared qualities come more from the life in their soils than their geological provenance.

I still read before and after vineyard visits. However, these days they are not wine books, they are soil books. It is in the soil you find great wine.

The 500 Milestone

Troon winemaker Nate Wall filling cow horns with fresh organic manure

You start with dung and end with humus. Newton was right, alchemy exists. What was worthless becomes gold. A concentrated collection of fungi and bacteria to inoculate our soils. This is not magic, just good bugs. 

We mark significant progress towards goals by celebrating milestones, events that measure our progress. Milestones should be recognized and remembered as you strive towards your goal. Some milestones are hard to measure, but in this case the achievement was very clear. Six months ago at Troon Vineyard we placed raw manure into some cow horns and last week we dug them up and out came soil - humus. The production of your first BD 500 is always a milestone for a Biodynamic farmer.

Why do you have to bury the manure in cow horns? The honest answer is that we don’t know, but we do know that no other container has successfully transformed manure into this important soil inoculate. Maria Thun, in her seeming endless research on all things Biodynamic tried to use other containers, but none produced the same results. For whatever reason, the cow horns are the only known container that transforms raw manure to the rich humus that is BD 500. Rudolf Steiner thought the cow horns channeled the power of the Universe into the manure. Personally, I believe that fermenting manure does not require quite that much energy. The fungi and bacteria are already here just waiting to do their jobs if given the proper opportunity. Right now, the cow horns do the best job of creating just the right environment for them to do their work. Perhaps in the future other containers will be discovered. 

The process of making BD 500 is actually quite simple. Last fall we gathered some very, very fresh cow manure from the pastures of Noble Dairy, our organic next-door neighbor (a great project for our harvest interns) and simply filled the cow horns with the fresh manure. The cow horns themselves came from the Josephine Porter Institute, perhaps the premier supplier for the Biodynamic farmer. Then we buried them last fall and dug them up early this summer. The transformation may seem magical, but it’s not as this is what the microbes in our soil do and all we did was provide them an opportunity to do their work in particularly pleasant conditions. 

So often we use mystical excuses to explain things we do not understand and there is still a lot we do not understand. Science and agriculture have had a difficult relationship. All too often, most scientific research focused on simply making more as bigger harvests promise more profit. The situation worsened as Big Ag took over the world. Quantity not quality generated the funding for most research with predictable results. In his book The Third Plate, chef Dan Barber relates the tale of university researchers being offered commissions by Monsanto to create wheat that was resistant to Roundup so that more of their product could be applied to grain on the way to a bakery near you.

Fortunately, things are changing and the microbiome of soil is the hot “new” topic being pursued by researchers. Many think what winegrowers have been calling terroir for centuries is actually more defined by the soil’s microbiome than the type of soil the vine is growing in. One thing for sure is that vines cannot take their nutrition from the soil without their mycorrhizal partners. The goal of Biodynamic farming is to build this natural balance in our soils. Healthy vines can handle many of the things Mother Nature throws their way without our help. In fact, often “our help” makes things worse for them. For some reason, we humans assume we know more about ripening grapes than grapevines do. 

After harvest this fall, our own BD 500 will be applied to our soils. There are those in Biodynamics that believe elemental beings are at work among their plants. I believe in them too. However, not the gnomes and such that some followers of Steiner believe in. The real elemental beings are the fungi and bacteria that work the real magic in the vineyard and are elemental to life itself. When we apply BD 500 to our soils we are just bringing more of those elemental beings to the party. 

Milestones are worthy of celebration and rituals. As a group, we gathered to fill and bury our horns and then again when we dug up the finished BD 500. We will all gather and celebrate again when we apply our own BD 500 to our vineyard this fall. We all come together to celebrate our milestones as we bring Troon Vineyard back to life.

In Biodynamics, the people are elemental beings too.

Planting New Vineyards at Troon - It Only Looks Like the Beginning

New vines arrived at Troon Vineyard yesterday from Inland Desert Nursery in Washington - mourvèdre, grenache noir and marsanne all neatly packed into shipping boxes. Next week more classic southern French varieties will arrive and within the next ten days, we’ll have planted over 14,000 vines to create ten new acres of vineyard.

Stacked in their shipping boxes they look like the beginning of a project, but it only looks that way. This project started a year and a half ago and the arrival of the vines themselves is closer to the end than the beginning of the project of planting a vineyard. The first step was extensive soil studies as Vineyard Soil Technologies dug more than seventy five-feet deep soil pits to create detailed soil profiles. Based on that data we selected ten acres as ideal for vineyard development. Combining the soil data and climate data with our experience we selected the varieties we felt would be best matched to each vineyard block to be developed. We then begin working with Inland Desert Nursery to obtain the clones of the varieties we chose to focus on. The varieties we were looking for are not the most popular so ordering from the nursery long in advance is required.

Planting does not begin with plants. First, there was the soil work and that filled most of the last year and a half. Once the blocks to be planted were identified the ground had to be prepared. That meant heavy equipment as a D8 ripped the ground to a depth of thirty-six inches. Prior to the ripping, we applied five tons per acre of organic compost along with other soil amendments that we discovered were required by our soil studies. This was followed by discing then yet another finishing discing. When the soil was prepared we seeded a specifically designed cover crop to add nutrition to the soil. As Biodynamic farmers, we also did our first application of Biodynamic Preparation 500.

Over the winter and spring, the cover crop prospered. This was then mowed, then disced into the soil as green manure. Then the vineyard begin to take form as we put in end posts, stakes for each vine (head-trained vines) and irrigation tubes for the soon to arrive young, and very thirsty vines. In addition, another application of Biodynamic preparation 500 was applied to both the blocks to be planted along with all existing vineyard blocks.

Only after all of this investment and work did we arrive at last Friday, when the first vines arrived. Their arrival was the culmination of all of this work, not the beginning. However, these vines mark the beginning of new wines that will come from the grapes they will yield. In that sense, they are truly a new beginning for Troon Vineyard.

As you see, the plan for planting these new acres at Troon was built upon scientific research, extensive viticultural experience, the principles of Biodynamic agriculture and on a vision to make wines with a unique character defined by our soils and the climate on the Kubli Bench in Oregon's Applegate Valley.

Over the next weeks, I will be documenting the process of planting these new vines at Troon Vineyard in words and images. I invite you to share that process with us as we build a foundation for a new generation of wines at Troon.

Taking the Parking Lot Back to Paradise

 Hey farmer farmer

Put away that D.D.T. now

Give me spots on my apples

But leave me the birds and the bees

Please

Don't it always seem to go

That you don't know what you've got

'Till it's gone

They paved paradise

And put up a parking lot

• Joni Mitchell, Big Yellow Taxi

I felt like I was walking on blacktop. Hard, hot and lifeless it looked like a place where a parking attendant would work, not a farmer. But this was a vineyard. Each vine looked like it was a weed growing out of cracks in the blacktop on some worn parking lot.

Living soil gives life. In this vineyard the soil was dead and the vines were dying. Yet, it was a beautiful site and the vines were giving some good wines even as they struggled to survive. They deserved better.

There seemed only one route back to health that could provide the opportunity to make the wines I believed we had the potential to produce. That path was biodynamics, which is the best existing framework for regenerative agriculture. To craft the wines we aspired to make, our soils, indeed our entire farm needed regeneration. It is never just the soil that needs regeneration, but also the spirit. At Troon, not only our soils were abused.

How was a vineyard transformed into a parking lot? Only through the abuses of industrial, thoughtless farming can soil be so decimated. Sick soils make sick plants and these poor vines were overcome with viruses and fungal diseases that stronger plants could have resisted. It became our mission to bring them back to health so they could live out their remaining years doing what Mother Nature intended them to do with their lives - ripen grapes.

Then there is intention, perhaps the key to regenerative agriculture. Previously their intent was to extract all they could from the land and extract they did. Today our mission is to give back more than we take. To be a good farmer you must work for the farmers who will farm the land in the future with the same fervor you work for yourself.

The path from parking lot to vineyard started with science. We did extensive soil studies with Vineyard Soil Technologies and worked with Biomemakers to establish a complete cross-section of our vineyard microbiome through genetic sequencing. To know where you need to go, you first have to know where you are.

Then came the proactive part - biodynamics. The essence of biodynamics is building healthy soils. The main tool in the biodynamic toolbox is compost. Over the last years we have been applying tons of biodynamic compost to our vineyards. In addition to the compost, now that chemicals were eradicated and weed control was returned to manual methods our soils began to change, the microbiome bloomed. Today you can walk into our vineyard and easily dig your hands into healthy arable soil.

That parking lot has been replaced by paradise - a vineyard.

More Biodynamic Fake News...

Harvest 2018 at Troon Vineyard in Oregon’s Applegate Valley.

Tired old canards. When will the media get on board with modern biodynamics? While the article Weighing Up the Value of Biodynamic Wine by Vicki Denig addresses valid concerns, once again the sources for the article are either misinformed or have an ax to grind. Here is a link to the original article:

https://www.wine-searcher.com/m/2019/04/weighing-up-the-value-of-biodynamic-wine?rss=Y

“Couple that with calendar-specific workdays and strict following of the lunar cycle, and even the smallest of vineyards would face significant time restraints and financial challenges. So when a sizeable estate decides to go biodynamic, is it actually achievable?”

“However, not all winemakers are convinced. In Crete, Giannis Stilianou, winemaker and owner of Stilianou Wines, explains that with larger properties, cultivating with biodynamic principles is nearly impossible, mainly because farmers are only permitted to execute vineyard work on a small amount of very specific days”

The Demeter standard for wines states, “Observation of the Biodynamic calendar is encouraged.” It does not demand only “calendar-specific work days or that “farmers are only permitted to execute vineyard work...on very specific days.” The statements above are false and following the biodynamic calendar is not required for Demeter Certification.

The work of all the biodynamic farmers I know is focused on regenerative agriculture. Their goal is to build the health of their soils and plants. In trying to follow the biodynamic calendar we are reaching for the very peak of quality. That extra edge that pushes our wines beyond just being delicious to becoming truly alive in the glass. If you can’t prune or pick on the ideal day due to weather and practical considerations you know that all of the other work you’ve done will still make exceptional wine. What we reach for by trying to do our work on certain days, by paying attention to the natural cycle of the Moon, is to go beyond simply delicious and make a wine that sings of the vineyard itself. A wine that is transparent and living.

“And for others, size isn't even the biggest issue. Stu Smith, partner and enologist at St. Helena-based Smith-Madrone Vineyards dug deep into the world of biodynamics – and still wasn't convinced. "I discovered that Rudolf Steiner had never been a farmer," he says, noting that Steiner went from student to agricultural theorist, without any experience in the field. Smith explains that when he'd challenge biodynamic farmers on their lack of trials and published results, their response was always that it's a belief system.”

Mr. Smith “discovered” that Rudolf Steiner had never been a farmer. Digging deep? An amazing discovery? I think not. Rudolf Steiner is famous for being a philosopher and founding the Waldorf schools, not for being a farmer, as a quick look at Wikipedia will show you. What we today call biodynamics was only outlined by Steiner in a series of lectures in 1924. He did not go from “student to agricultural theorist”, but gave the lectures at the end of his life at the request of a group of farmers. The modern practice of biodynamics has been built after his death on the experience and experiments of several generations of biodynamic farmers. None of the biodynamic wine growers I personally know consider biodynamic farming a “belief system”, but see it as a framework to build on with a goal of taking their farming to a new level. Contrary to what Mr. Smith may believe, Nicolas Joly is not your typical biodynamic winegrower.

“Smith also takes issue with what he deems to be close-mindedness amongst biodynamic farmers, from both large and small estates. "They are the only group out there that says 'our way is the only way, and everyone else is doing it wrong'. Organic and sustainable farmers don't do that, but biodynamic farmers do."

This, simply, is total bullshit.

“And when it comes down to it, Smith sees it all as a fast-track to making money. "There are so many wineries that need to find their place in the sun," he says, calling out the appeal of biodynamics to Millennial consumers. "In my opinion, it's a marketing ploy – do you see biodynamic carrots? Lettuce? Peaches? No. They're doing it in wine in America as a marketing concept so they sell their product easier and get a higher price for it."

Yes, Mr. Smith, you do see biodynamic carrots, lettuce, and peaches, just not enough of them. The reason you see few of these biodynamically certified fruits vegetables and wines is that practicing biodynamics is hard work and unlikely to reward with you with enough additional profit to justify the effort. You choose biodynamics because of a commitment to reach for something special. Demeter USA currently has certification protocols for Fruit and Vegetables; Nuts, Seeds and Kernels; Bread, Cakes and Pastries; Grain, Cereal, Tofu and Pasta; Herbs and Spices; Meat; Dairy; Oils and Fats; Sweetening Agents, Confectionary, Ice Cream, Chocolate; Cosmetics and Body Care; Textiles; Wine; Beer; Spirits; Cider and Fruit Wines; Infant Formula. It seems he is shopping in the wrong markets, perhaps he should give Google a try?

Then there is his “marketing ploy” statement, which any accountant for a biodynamic winery would get a big laugh over.

“Others think that many biodynamic practices are, frankly, bullshit.”

I'll tell you the real bullshit. It’s farming with chemicals that destroy the environment and cause cancer. It’s making boring industrial wine. If a little voodoo will save the planet, count me in. Voodoo is just what people call something they don’t understand.

Becoming One with Wine

The world feels somehow different today at Troon Vineyard. I guess you can’t reinvent a vineyard without reinventing yourself. Reinventing and reinvigorating people and a vineyard at the same time is about the simplest way I can explain our transition to biodynamic farming. Everything just feels more alive.

Over the last week what was all planning, items on a Trello board, started to become real. New equipment, new ways of thinking and a new spirit all converged at Troon Vineyard this week. The first step was just a simple piece of string

Twine ties in a block of our vermentino

After years of plastic ties in the vineyard, many of a particularly noxious green color, we have replaced them with hand-knotted pieces of twine. The contrast between the bilious green of the old ties and the warm, earth tones of the twine ties running down the rows tying the canes to the wires could not be more obvious or meaningful. A simple change that tells of significant changes to come, we are becoming entwined in nature.

A somewhat physically more prominent change was the arrival of our Clemens radius weeder or “weed knife”.  While a big financial investment, an efficient tool to control weeds is necessary if you are going to forgo chemicals like the seemingly ever-present Roundup. Many may debate about the evils of glyphosate, and all too many sustainable certifications allow it, but common sense tells us that chemicals like these are just not part of nature’s plan.  It’s hard to describe how well the Clemens does its job as it fluidly dances the blade around each vine almost in slow motion - we actually it is in slow motion as the tractor can only go two and a half miles an hour while doing this work.

Other new mechanical arrivals include the Clemens multi-clean undervine brush, which, as the name implies, literally whisks away suckers and weeds around the base of the vine. Then there is a tank-like Domries disc and a Domries tri-till cultivator. We now have the tools to do the job right.

Creating a vortex while stirring BD 500

Then there was the really good shit, literally, which arrived this week. Now living in Southern Oregon, that phrase tends to refer to other local agricultural products, in our case, it was actually shit. This was the famed BD 500, the cow manure aged in buried cow horns. For this first application we had to purchase some finished BD 500, but by next spring we’ll have buried and fermented our own. The finished preparation does not remind of the original state or aromatics of the raw materials as it looks and smells more like very rich potting soil. To prepare 500 for application requires stirring it a very particular way. Troon winemaker Steve Hall selected one of our oldest barrels (for the history of place it had experienced) then after adding the 500 to around forty gallons of water we begin the stirring process. Steve and I alternated during the hour long process. First you stir in one direction until you build a deep vortex then suddenly reverse direction going violently from order to disorder. You repeat this process over-and-over for the full hour. This was a uniquely satisfying  experience as you bond with the preparation that will become one with your soil. A very different experience than wearing haz-mat gear demanded by standard vineyard applications. Once prepared we poured the BD 500 into the sprayer and as the week came to a close our entire property had received this application. 

Just knowing that the first biodynamic preparation is in our soils gives me both a sense of peace and accomplishment. We are on an entirely new voyage with a new mission. Just as the vines are reborn each spring, this spring Troon Vineyard is reborn along with them. Soon the buds will break into a whole new world of winegrowing. 

Biodynamics will reinvigorate our soils and our vines, but it is also reinvigorating us. It is those combined energies that will be expressed in our wines. Wines full of energy are exciting wines and we could not be more excited about making them. Our desire to make special wines from what we know is a vineyard, a terroir, with exceptional potential is what started us on this voyage to begin with. 

We are at the starting line of a long struggle to achieve our goals. Now that we have taken our first steps we feel like a sprinter whose energy has just been released by the starting gun. 

The vines, the soil, the place, the wines and the people are all becoming one.

Electromagnetic Soil Scanner

Our soil studies at Troon Vineyard started today with Nick Madden here for the day to do a complete electromagnetic soil scan of our vineyard blocks. We've retained Dr. Paul Anamosa and company to do a complete analysis of our vineyard blocks. Armed with this scan data we will be selecting locations for about eighty 5 feet deep pits to fully map our soil types. This data will help us select the proper varieties as we add new vineyard blocks and replant old ones. The scanner is on the sled behind the ATV. Here is some information on exactly what Nick is doing https://d.pr/dtaYMK

”Electromagnetic induction (EMI) has been used to characterize the spatial variability of soil properties since the late 1970s. Initially used to assess soil salinity, the use of EMI in soil studies has expanded to include: mapping soil types; characterizing soil water content and flow patterns; assessing variations in soil texture, compaction, or- ganic matter content, and pH; and determining the depth to subsurface horizons, stratigraphic layers or bedrock, among other uses. In all cases the soil property being investigated must influence soil apparent electrical conduc- tivity (ECa) either directly or indirectly for EMI techniques to be effective. An increasing number and diversity of EMI sensors have been developed in response to users' needs and the availability of allied technologies, which have greatly improved the functionality of these tools. EMI investigations provide several benefits for soil studies. The large amount of georeferenced data that can be rapidly and inexpensively collected with EMI provides more complete characterization of the spatial variations in soil properties than traditional sampling techniques. In addition, compared to traditional soil survey methods, EMI can more effectively characterize diffuse soil bound- aries and identify areas of dissimilar soils within mapped soil units, giving soil scientists greater confidence when collecting spatial soil information. EMI techniques do have limitations; results are site-specific and can vary depending on the complex interactions among multiple and variable soil properties. Despite this, EMI techniques are increasingly being used to investigate the spatial variability of soil properties at field and landscape scales.”
