This extra special reserve Russian Imperial Stout went through our strict Flying Buffalo aging process in bourbon barrels for 10 months before a second sleep of 4 months in freshly emptied Rye Whiskey barrels. Under the watchful eye of our head brewmaster, this double barrel process results in a complex, smooth, smoky, earthy, oaky, and intensely delicious stout experience. Possibly the most intricate Buffalo yet to take flight.
