Arietta was founded in 1996 by Fritz and Caren Hatton with John and Maggy Kongsgaard, building its identity around limited-production Bordeaux-style blends sourced from cooler Napa sites. Early wines centered on a small Cabernet Franc block at Hudson Ranch, later expanding to Merlot, Syrah, and select Cabernet Sauvignon parcels from Howell Mountain and Coombsville. Andy Erickson became winemaker in 2005, introducing the white wine On The White Keys from Sauvignon Blanc and Semillon. Arietta continues to produce small-lot wines at Hudson Winery, emphasizing meticulous fruit selection and long-term grower relationships.
