Napa Valley winemaker Pine Ridge Vineyards has unveiled its first sparkling wine. The wine ($18 a 750-ml.) is made from Chenin Blanc sourced from Clarksburg and Viognier from Lodi and serves as an offshoot of the winery’s popular Chenin Blanc + Viognier still white blend. It’s the brand’s first new label in 25 years. Pine Ridge Chenin Blanc + Viognier sparkling wine is available in select markets, with expansion planned.
