Hearthstone Vineyard & Winery was established in 1999 when Hoy Buell, a Cal Poly graduate and horticulturist for 28 years, combined his planting and growing expertise with his love for fine wines. He first planted a parcel in the heart of majestic Adelaida, developing what is now Hearthstone Vineyards in 1999. The first vintage from Hearthstone débuted in 2003. We make up to 3000 cases per year depending on Mother Nature and make predominently unique blends from our 40 acre Estate Vineyard.
