Welcome to Suisun Valley: Where Exceptional Wine Begins

For decades, the Suisun Valley appellation has been quietly crafting extraordinary wines, a legacy honored each December at the Anniversary Celebration event. Nestled just 8 miles long by 3 miles wide, this hidden gem, officially recognized by the TTB in 1982 and included in the larger North Coast AVA in 1983, boasts a remarkable terroir.

With an impressive 14-degree daytime temperature differential between the lower and upper valleys, Suisun provides the ideal conditions for a diverse range of varietals. This isn’t by chance; groundbreaking climate studies by Dr. Paul Skinner of Terra Spase have revealed the profound impact of marine air flowing directly from the Pacific over San Pablo Bay into the valley. The substantial marine influence contributes to the exceptional growing conditions of the region. This key factor enables precise site selection, resulting in the cultivation of white wines with preserved acidity and red wines with ideal ripeness.

The quality of Suisun Valley fruit speaks for itself. Consistently earning Gold, Silver, and Bronze medals, 90+ point scores, and critical acclaim, these wines are a testament to the excellence of the appellation. From classic Cabernet Sauvignon and Chardonnay to unique varietals like Trousseau Noir and Malvasia Bianca, Suisun Valley growers cultivate a wide selection of grapes, ensuring something exceptional for every palate.

In recent years, western hillside plantings that commenced in 2015 have added another exciting dimension. These vineyards, situated on volcanic rock geologically associated with the Mt. George Range, are already yielding highly encouraging results with Cabernet Sauvignon, Zinfandel, Grenache, and Petite Sirah.
