In 1998 Jim and Cindy Ragni planted 2 acres of Pinot Noir Pommard clones on their native roots in Willakenzie and Yamhill soils. They named the vineyard after Cindy's grey Arabian. The first harvest was in 2000 and they developed the vineyard into one of the prime estate vineyards in the Yamhill-Carlton AVA. After the sale of her family farm in Leipsic, Ohio, Jane Kneller purchased the vineyard in Fall 2012. She and her husband Michael Losonsky farmed the vineyard organically and it was certified organic by Stellar in 2016. With the help of their children Rosa and Miro, they planted a block of Chardonnay in 2015 and in 2016 a block of Pinot Noir (Dijon clone 115) was added. Greyhorse Vineyard grapes have been vinified by Dobbes Family Estate, Omero Cellars, and Swick Wines. Jane and Michael manage the vineyard and Miro is the viticulturist.
