Bourbon barrels are delivered in a variety of conditions when ordered. The condition depends on a myriad of factors including their age, storage time, and method of transportation. The most important thing to immediately assess is how likely the barrel is to leak. Barrels are made up of individual pieces of wood, called staves, which are held together with metal bands, called hoops. The wood used for staves, often white oak, is split and aged and dried. When properly cut, trimmed, and assembled, the staves fit tightly together and swell to become waterproof in the presence of a liquid. If a barrel is allowed to dry, the staves can shrink and the barrel may leak. Leaks can also come from barrels that are damaged in storage or transport. In the case of the barrel used by CAMRA, we had no idea how long the barrel sat before being transported to us after purchase. We also stored it for several months before we were ready to fill it, so there was concern about potential leakage

The CAMRA barrel was empty, but smelled fantastic of Virginia Gentleman from the A. Smith Bowman Distillery, which is the bourbon it contained. If the barrel contains any liquid bourbon, it is advisable to collect it, as mixing it in with the beer will likely give an overwhelming bourbon character. There is plenty of bourbon absorbed in the wood already. The lack of bourbon in the barrel increased our fear of barrel leaks, but we decided to proceed anyway. The barrel was stored on a small barrel rack at a local homebrewing shop, Fifth Season, and we could watch underneath the barrel to catch any developing leaks early.
The barrel is now topped up and has an airlock in case of changing pressures. The plan is to taste it in a month and see how the flavors are developing. We do not want to taste it more frequently and risk oxidation or infection. Because new barrels can quickly provide bourbon and oak flavors, it is likely we will need to change the beer out in as little as a few months.
Thanks again to Fifth Season for hosting the barrel and to Greg W. for organizing the project. I am looking forward to seeing how the beer turns out.
Cheers,
TW
