I have a bourbon barrel I've used twice for bourbon barrel stouts. I keep Makers Mark in it when it's not holding beer. After I bottle, I rinse out the barrel and dump in another bottle of Makers.
My question is, can I dump out the bourbon, rinse it really well, and pour in a bottle or two of rum and keep shaking it around every other day to turn it into a rum barrel? Is the char different or anything or is the bourbon already an overwhelming presense? Maybe it would be a unique combo?
In a few weeks, I'll have a vanilla porter that will be ready and was wanting to age it for awhile in a rum barrel or at least what would seem like a rum barrel.
Is this possible? If so, what type of rum would be good to use? Any thoughts?
