JaM Cellars

Napa Valley Cabernet and Chardonnay with prestige critic recognition.

JaM Cellars produces wines from Napa Valley, the North Coast region of California known for structured Cabernet Sauvignon and refined Chardonnay. The winery's portfolio centers on Cabernet Sauvignon, with the Butter Cabernet Sauvignon and California Cabernet Sauvignon as flagship expressions. Both have earned recognition from Decanter and Wine Enthusiast. The Butter Chardonnay, Napa Valley, rounds out the core range. Napa Valley's warm days and cool nights create the conditions for ripe fruit and balanced acidity—hallmarks of the region's most compelling wines. JaM Cellars' focus on these two classic varieties reflects the terroir and winemaking tradition of the valley.
