Holding all other variables constant, we wanted to see the effect that barrel size had on the finished product. A typical bourbon barrel holds 200L and in this experiment we aged bourbon in two larger barrels-250L and 500L on the same floor for the same amount of time to examine the impact on the flavor profile. What we found was that the 250L had a distinctive flavor profile similar to our control barrels, whereas the 500L was more tannic, oaky, and dry.
