Hearthstone's 40 acre vineyard is located in the heart of historic Adelaida, west of Paso Robles. The vineyard sits at 1400 feet surrounded by wooded hillsides. The soils are shallow clay and limestone,which, along with their natural farming methods, contribute to the intense flavors of their fruit.

The newly opened tasting room offers visitors a range of 100% estate grown wines to taste, including their counter top "barrel sample" from their cellar. The winery is built into the slope of the hillside and is naturally cooled. The gift shop has apparel, glassware and photographs for sale. Outside there is a small fountain, shade and tables to sit and enjoy the countryside views.

Hearthstone focuses on red wines producing 11 such wines including a number of good Rhone offerings, Zinfandel, Cabernet and Pinot Noir. Also look for their Sangiovese and a California Italian blend. Their food friendly wines are available at many fine shops and restaurants in the area at the winery and through their wine club.
