I have 2 5 gallon carboys going (Of the exact same recipe)
I want to put one of them in an oak barrel, however it won't fill it all the way. Which is something I need to keep the wood soaked and keep oxygen out.
Would it be a bad idea to put a slight amount of one into the other to fill?
Exact same recipe and brew. Only difference is a few days between making. Primary is done I would hope because they have been sitting for a good 2 months so far.
Any input would be greatly appreciated
