Cowhorn Vineyard & Garden
The Free Bacchus Story
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.

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.
