Testarossa is known for its premier California cool climate Chardonnay and Pinot Noir. We work with the highest quality California vineyard owners and growers in the best appellations for California chardonnay. With more than a dozen single vineyard chardonnays and a few appellation blends, there is always a style in Testarossa’s portfolio to satisfy every palate. Director of Winemaking Bill Brosseau is meticulous in his barrel selection to match with the style of each vineyard allowing the wine to truly express it’s terrior. We top our beautiful selection of chardonnays with Diana’s Chardonnay from the Jensen Reserve Society, made from the best barrels in our cellars. Diana’s represents our highest achievement in winemaking.
