The base beer is a Pilsner aged in Sauvignon Blanc barrels with the addition of Sauvignon Blanc grape juice from the 2018 harvest for a secondary fermentation. The juice and barrels are from Dutton Vineyards in the Russian River wine appellation here in Sonoma County. There is no lactobacillus or pediococcus added to the beer, only brettanomyces. The tart acidity comes from the wine grapes. This beer is delicate and beautifully balanced, a perfect refresher on a warm summer day!russianriverbrewing.com
Russian River makes world class sours and Intinction is a good example of their expertise. I can’t imagine a better blend of Pilsner malt, white wine grape influence, and sour acidity. Reading the label I imagined something muddy, not understanding how Pilsner malt and white wine would work together. I wisely gave Russian River the benefit of the doubt and was rewarded with a complex and refreshing beer, that manages to delightfully highlight each of its ingredients. The Pilsner malt takes the stage at first, but the beer has a lovely oaky white wine finish.
