Horsepower is an offshoot of Cayuse, the Walla Walla domaine founded by Christophe Baron, a French vigneron who has been making highly-acclaimed Rhone-style wines in Walla Walla Valley since the 1990s. The name Horsepower is not metaphorical. Starting in 2008 Baron began farming several acres of his estate using Belgian draft horses rather than tractors. Baron descends from a long line of French vignerons, and from the beginning he has farmed his Walla Walla vineyards bio dynamically. He took his interest in traditional French vineyard management a step further when he brought in his first draft horse, Zeppo. In 2009 he added a second horse, Red. With custom made cultivation equipment the horses can navigate tightly-spaced vineyards that harken back to planting systems of 19th century French vineyards. Horsepower owns four vineyards which are planted, with Rhone varietals. Horsepower wines have been very well reviewed.
