I recently acquired a 3 gallon bourbon barrel and have an imperial stout aging in it now. I will taste it periodically to see how it is progressing. However, I was wondering who else out there has used a barrel of this size and has a time recommendation. My main concern is it may be a month before I am able to brew again, then a few weeks until the next beer is ready to go in the barrel. I want to avoid having the barrel empty for too long. Ideally I would want to drain the stout and put in the next beer, a scotch/wee heavy.
