Epoch Estate Wines Epoch Estate Wines Beverages: AlcoholicConsumer Non-Durables Epoch Estate Wines is a family-owned winery dedicated to producing artisanal, terroir-driven wines from its three estate vineyards: Paderewski, Catapult, and York Mountain. The private company is based in Templeton. The winery specializes in Rhône varietals, Zinfandel, Tempranillo, and Bordeaux grapes, emphasizing site-specific expressions that reflect the unique soils and microclimates of each vineyard. The Paderewski Vineyard features steep, limestone-rich hillsides with diverse grape varieties, while the Catapult Vineyard is situated on rocky, siliceous shale soils with a cooler mesoclimate, planted with Rhône reds and whites. The mountain winery, restored after earthquake damage, serves as the tasting room and incorporates original architectural elements. Epoch Estate Wines offers educational tasting experiences, winery tours with food pairings, private group events, and a customizable wine club with biannual shipments and exclusive benefits. The modern winery facility combines sustainable design with advanced winemaking technology. The American company was founded by William D. Armstrong.	Founder	-
