Peter Michael Winery is a family-owned winery established in 1982 by Sir Peter Michael. It is located in the northeastern part of Sonoma County, California, on the slopes of Mount St. Helena.

Peter Michael Winery produces wines from varieties such as Chardonnay, Pinot Noir, Cabernet Sauvignon, and Sauvignon Blanc, employing traditional winemaking methods including hand-sorting of grapes, fermentation with indigenous yeasts, and aging in French oak barrels. The Michael family has a long-term vision to keep the winery family-owned for at least 100 years, with a strong commitment to preserving the natural environment and wildlife surrounding the vineyards.
