About Pocai Vineyard

Betty Ballentine’s grandfather, Libero Pocai, purchased the vineyard in 1906 with gold coins saved from working in the lumber mills. The property has been continuously farmed by our family for over 100 years and is the heart and soul of Ballentine Family Estate. The Pocai Vineyard produces big red wines with robust tannins that are expressive and playful on the palate and pair exceptionally well with a variety of foods.
