OUR HONORARY HOST & CHAIR
Opus One Winery

As one of Napa Valley’s most recognized wine estates, Opus One represents a powerful example of what long-term viticultural stewardship can achieve. Founded in 1978, with a historic 50/50 joint-venture between Baron Philippe de Rothschild and Robert Mondavi, the winery represents a commitment to craftsmanship, innovation, and collaboration to support and protect Napa Valley’s vineyard lands.
Situated in Oakville, Opus One farms its vineyards with a deep respect for the land and the generations of growers who helped build Napa Valley into one of the world’s great winegrowing regions. Through careful vineyard management, investment in agricultural excellence, and global leadership in fine wine, Opus One demonstrates how thoughtful stewardship of vineyard land and meticulous winemaking sustain both the local community and the broader agricultural legacy of Napa Valley.
As Host of the 2026 Harvest STOMP, Opus One shares a setting that reflects the spirit of the evening with an estate where vineyards, regenerative farming, and tradition meet, and the story of Napa Valley agriculture continues to be built.
Few individuals embody the connection between Napa Valley vineyards, winemaking excellence, and industry leadership as fully as Michael Silacci. As VP of Winemaking at Opus One for 25 years, Michael has stewarded the winery’s Oakville vineyards with a philosophy that places the land at the heart of every vintage.
Michael’s commitment to Napa Valley extends well beyond the winery. For nearly a decade he served on the board of the Napa Valley Grapegrowers, including two years as President, helping guide the organization’s work in advancing viticultural education, advocacy, and protection of the valley’s agricultural landscape.
As Honorary Chair of the 2026 Harvest STOMP, Michael brings together the roles he has long embraced: winemaker, grower advocate, and steward of Napa Valley’s future. Hosting the event at Opus One reflects both his personal dedication to the region and a shared belief that the strength of Napa Valley begins in its vineyards and the community that sustains them.
