Five & 20 Déjà vu Bourbon starts out in new, charred American oak barrels that provides the robust caramel and vanilla notes which complements the sweetness of the bourbon.
After this initial aging, the whiskey is transferred into freshly emptied Commiseration Imperial Stout beer casks from the Five & 20 brewery. Because the casks came from their own brewery, they were filled with whiskey within 24 hours of the beer being removed. This ensures the freshness of the barrels which provides the maximum flavor and aroma impact. The extra aging in these beer casks gives the whiskey a sweeter, roastier character that complements the sweet corn and caramel notes of the bourbon whiskey.
