This Phifer Pavitt Reserve Bourbon is the first release for Bardstown Bourbon Company under the brand's Collaborative Series. They partnered with Napa Valley's Phifer Pavitt Winery who supplied the cabernet sauvignon wine barrels for the bourbon to finish its aging in. Bardstown took 9 year-old Tennessee straight bourbon and aged the whiskey in these French oak wine barrels for 19 months further.
