About Us / Opus One History: Winemaking at Opus One resolves to a single goal: to produce an extraordinary wine. No compromises are made. Guided by the vision of our founders, our winemaker Michael Silacci combines intuition and technical acumen with the dual perspective of viticulturist and winemaker. Every cluster of Opus One grapes is hand-harvested, and just as much care is taken when transporting them from the vineyard to the winery.
