Bardstown Bourbon Company’s Collaborative Series Silver Oak pairs Kentucky bourbon with one of Napa’s most famous cellars finishing the whiskey in American oak barrels that previously raised Silver Oak Cabernet Sauvignon. The Collaborative Series exists for exactly this kind of cross-pollination, and the wine casks earn their billing: dark fruit and toasted oak fold into the bourbon’s caramel core, with cherry, baking spice, and a wine-kissed richness carrying a long, layered finish. Bardstown’s modern Nelson County campus has become one of American whiskey’s most decorated producers, and this is the house style at its most expressive. A limited release built for slow evenings pour it neat and let the cabernet influence surface as it opens.
