Cowhorn Vineyard & Garden

Last verified · August 2026
Cowhorn Vineyard & Garden, in the Applegate Valley, southern Oregon.

The estate is named after a cow horn — specifically the one used in biodynamic preparation 500, where manure is packed into a horn, buried through the winter, dug up and applied to the soil in spring. It is the practice sceptics reach for first when they want to dismiss biodynamics as nonsense, and Bill and Barbara Steele put it on the sign.

They established Cowhorn in 2002 on 117 acres in the Applegate Valley, a Southern Oregon sub-appellation sitting higher and drier than the Willamette, with a Mediterranean climate that suits Rhône varieties rather than Pinot Noir. The biodynamic commitment was part of the founding design rather than a later conversion, with livestock, cover crops and composting integrated from the start.

Cowhorn Vineyard & Garden
Established in 2002 on a hundred and seventeen acres in the Applegate Valley, Southern Oregon.

Barbara Steele's stated position is that agriculture is extractive by definition, and that the job is to do it in a way that leaves the ground better than it was found.

Whatever one makes of preparation 500's origins in Steiner's lectures, estates applying it consistently over years have recorded measurable improvements in soil biology, and the wines here have not suffered for the association. The Spiral 36, a Syrah-dominant blend, has drawn 95 points from Wine Advocate, with the Grenache and Viognier attracting comparable attention.

Distribution is limited, and most of it goes through the mailing list and tasting room, which keeps production stable and the quality consistent. The estate that advertises the ritual on its own sign keeps out-scoring its region, which is worth remembering next time the subject comes up.

Why it’s remarkable

Full Living Certified
the tasting room meets one of the hardest building standards there is
Living Building Challenge 2.1, certified in full, occupied from June 2016. Two thousand two hundred square feet running at net zero energy on a ten-kilowatt solar array using Passivhaus strategies. Almost nobody in the wine trade has attempted this standard, and fewer have passed it.
10% set aside
the biodynamic standard requires land taken out of production
A minimum tenth of total acreage must be given over to biodiversity rather than crops. On a property of over a hundred acres that is real ground deliberately not earning, and it is a requirement most people do not realise the Demeter standard contains.
The only one
Demeter-certified biodynamic vineyard in southern Oregon
Being the only certified estate in a region means there is no local peer group, no shared supplier base for preparations, and nobody nearby who has already solved the same problems.
‘Extractive by definition’
their own description of what farming is
Barbara Steele’s stated position is that agriculture is extractive by definition, and that the job is to do it in a way that leaves the land at least as good as they found it. That is an unusually unsentimental framing from a producer at this end of the spectrum, and a more honest one than most.
