How much bourbon would a bourbon maker make?

One Saturday in October of 2008, I followed the Kentucky Bourbon Trail to two distilleries: Buffalo Trace and Woodford Reserve.

Informative and entertaining tours, wonderful facilities, and delicious liquids.

But after returning, I realized that there were two questions I hadn't asked. (Or if someone had, the sweet mash may have dulled the memory.)

• What is the size of a bourbon barrel?
• Is there a legal volume requirement for the volume?

I asked Lew Bryson, editor for Malt Advocate Magazine, for help. He, in turn, asked Larry Kass of Heaven Hill Distillery.

And Larry asked Mike Veach, the 'answer guy' at the Filson Historical Society, a center for the study of the history and culture of the Ohio Valley.

Mike's full response is published at Lew's blog Seen Through a Glass. The short answer? Here's a visual clue:


Fifty-three US gallons, give or take, seems to be the current industry standard. There is no legal standard, however.

In an email to me, Mike added:

The main thing determining the size of the barrel is the size of the warehouse ricks. If the barrels get too big or too small for the ricks then the whole system falls apart and the distilleries would have to replace their warehouses.

The ricks are the wooden supports upon which the full barrels rest as they age. The rickhouse is the warehouse in which the barrels age.



Lew recently published an update. The US Treasury Department, in 1968, rejected a request to set the maximum volume at 53 gallons.

Imagine that. The government turned down the opportunity to regulate.
