Alienor produces wines from Lake County, in California's North Coast region. The winery's portfolio centers on three flagship wines: Côte de Castelero, a Shiraz expression; Sauvignon Blanc; and Grand Vin Red, a Cabernet Franc and Merlot blend. Wine Enthusiast has rated these releases, with Côte de Castelero achieving particular recognition among prestige critics. Lake County's warm days and cooling influences support both bold red varieties and crisp white wines. The winery's focus on Shiraz and Sauvignon Blanc reflects the region's capacity for ripe fruit and aromatic intensity, while the Cabernet Franc and Merlot blend speaks to the area's suitability for structured, age-worthy reds.
