Mersenne

California Cabernet and sparkling Sauvignon Blanc with prestige critic recognition.

Mersenne produces wines across California's diverse terroirs, anchoring its portfolio in two distinct expressions. The Cabernet Sauvignon draws on the region's capacity for structured, age-worthy reds built from the classic variety. Prospére, a sparkling Sauvignon Blanc, captures the aromatic brightness and mineral tension that the grape brings to wine. Wine Enthusiast has rated both offerings, with the Cabernet Sauvignon earning particular recognition. The winery's focus on these two wines—one still and structured, one effervescent and crisp—reflects a deliberate approach to California's range of expression.
