Shibumi Knoll is located in the center of the Napa Valley .3 miles off Highway 29 and a quarter mile from the Napa River. It is on the alluvial fan of Mill Creek and is composed of 80% rock. The first vintage was in 2003, the grapes were processed at Benessere Winery located about a half mile north of Shibumi Knoll. There, while watching the grapes being processed, owner Don Ross met another vintner, Eugena Keegan, who was bringing in Chardonnay grapes from Sonoma County. Eugena asked Don if he’d like to barrel taste her wines. The last wine he tasted, a Chardonnay from Buena Tierra Vineyards, he felt was stunning. Eugena was moving to Oregon so he approached the owner of Buena Tierra Vineyards, located on the Russian River in Sonoma county about buying the grapes. The owner explained that because the vines were 35 years old and grape production was down, he was going to replant the 2.4-acre block. Don offered to pay full production price for whatever grapes were harvested, an agreement which has continued for 16 years.
The Shibumi Knoll Buena Tierra Chardonnay has proven to be among the best in the country. The 2005 vintage received a 97 from The Wine Spectator, tied for the highest score given California Chardonnay in the first decade of this century. This ancient block of vines has produced some incredible Chardonnay vintage after vintage. The Buena Tierra Vineyard was planted in 1978, making it one of the oldest vineyards in the Russian River Valley. Owned and farmed by Joseph R. Miller, this venerable vineyard is located 1.5 miles southeast of Rochioli Vineyard in the low hills of the Laguna Ridge where the Russian River turns to head west to the Pacific Ocean. The site is ideal for Chardonnay, with well-drained sandy clay loam soil, cooling morning and evening fog from the ocean and bright sunshine during the day. Selectively irrigated, the vineyard is planted to several clones.
