Beringer Bros Cabernet Sauvignon Bourbon Barrel California 750ml150 years ago, Jacob and Frederick Beringer were pioneers of a new age, making their way across the frontier to plant their first vines in Napa Valley. Today, we remain true to their bold, pioneering spirit with Beringer Bros. Bourbon Barrel Aged Wines. Our latest varietals are aged for sixty days in charred, American oak bourbon barrels. The result: a uniquely rich, warm, and bold flavor.
