Hanzell produces Chardonnay and Pinot Noir in Sonoma County's North Coast region. The Ambassador's 1953 Vineyard Chardonnay, the winery's flagship white, has earned a prestige rating of 94.6, while the Farm The Ramos Selection Chardonnay follows at 94.0. The Ambassador's 1953 Vineyard Pinot Noir, the estate's signature red, rates at 93.7. These wines have been assessed by Wine Enthusiast, Wine Advocate, Wine Spectator, Decanter, and Falstaff. Sonoma County's cool coastal influences and varied microclimates support the precision and complexity these varietals demand—Chardonnay's mineral tension and oak integration, Pinot Noir's silky tannins and aromatic depth. Hanzell's focus on these two grapes reflects a commitment to the region's strengths.
