Marchesi Antinori is solidifying its foothold in Napa Valley, buying complete control of Stag's Leap Wine Cellars from Ste. Michelle Wine Estates. The two companies announced today that Antinori, which has been a minority partner at the iconic Napa winery since Ste. Michelle purchased it from founder Warren Winiarksi in 2007, is buying Ste. Michelle's 85 percent stake.

The sale includes the winery, the brand and inventory, and close to 300 acres of Napa vines, including the Fay and S.L.V. vineyards. Neither side disclosed the purchase price. A former college professor turned Napa winemaker, Warren Winiarski founded Stag's Leap in 1970, after a stint at Robert Mondavi winery. He quickly showed off his technical skill and the promise of his corner of Napa Valley.
