Bathed in the allure of the Napa Valley, the Calistoga AVA boasts a captivating climate shaped by cool marine air from the northwestern hills. Daytime summer temperatures may peak above 100° and fall to the cozy embrace of the low 40s at night. Gentle afternoon and evening breezes grace the region, while clear nights are accompanied by a soothing descent of cold air from the mountainsides. Here, the land flourishes with Cabernet Sauvignon, Zinfandel, Syrah, and Petite Sirah.
