Weve replaced the wheels of time with barrel heads. They dont turn, yet they embrace the evolution of beer and time on a level that cant be rivaled. For this Chronology Series, we brewed an imperial porter and set it to age in bourbon barrels. Every six months, we took a quarter of the barrels, blended them and bottled them. This second bottling represents the nuances imparted to the base beer after twelve months of barrel-aging.
