Simi Winery is one of the oldest and most historic wineries in California's Sonoma County, with a legacy that dates back to its founding in 1876 by two Italian immigrant brothers, Giuseppe and Pietro Simi. The brand's identity is a powerful blend of its deep heritage, a focus on quality, and a unique history of strong female leadership.

A key part of the brand's story is the resilience of Isabelle Simi, Giuseppe's daughter, who took over the winery at the age of 18 in 1904. She not only steered the business through the challenging period of Prohibition, but also had the foresight to store a large amount of wine in the cellars, which gave the winery a massive advantage when Prohibition was repealed. This act of determination and savvy has become a central part of the brand's narrative.

Simi is known for producing a diverse range of wines, with a particular emphasis on Cabernet Sauvignon and Chardonnay. They source grapes from various prestigious appellations within Sonoma County, including Alexander Valley and Russian River Valley, to craft wines that are a true expression of the region's terroir. The brand is also recognized for its commitment to sustainability, having been certified as a green winery. Now owned by Constellation Brands, Simi maintains its focus on producing high-quality, approachable wines that honor its long-standing tradition.
