Cass Vineyards and Winery is located in the rolling, oak-studded hills on California's beautiful Central Coast. This area offers quiet serenity for the visitor and a perfect growing season for wine grapes. Far enough from the coast to generate the heat needed to optimally ripen the Rhone varieties grown in our vineyards. One hundred percent of the wines crafted at Cass Winery are Estate Grown. Our vineyard surrounds our Tasting Room and winery. You can literally touch, taste, see and smell the grapes from the block where they were harvested. A unique feature of our wine making is that all of the Rhone grapes we grow are ENTAV certified. ENTAV (Establissement National Technique pour l’Amelioration de la Viticulture) is the national agency of France responsible for the quality of wine grape varieities. Over 90% of all French Vineyards are started with ENTAV certified plants and are only recently available in California. Consequently, these are among the very first wines made from ENTAV grapes grown here.
