Arietta operates in Oakville, the heart of Napa Valley's Cabernet country, where mountain slopes and valley floors create ideal conditions for premium red wines. The winery's portfolio centers on Merlot and Bordeaux blends sourced from Hudson Vineyards, a site known for producing structured, age-worthy fruit. The Merlot Hudson Vineyards stands as the flagship red—a wine that has drawn attention from Wine Advocate, Wine Enthusiast, Wine Spectator, and Decanter. The H Block Hudson Vineyards, a Merlot and Cabernet Sauvignon blend, offers a more complex expression of the same terroir. Arietta also produces Quartet Sauvignon Blanc, a white wine that demonstrates the winery's range beyond its red-wine focus. The combination of Oakville's reputation for elegant, age-capable reds and Arietta's selection of vineyard sources positions the winery within the region's quality-driven tradition.
