My friend got one of these as a gift
And now has a barrel that he wants me to age some beer in. Any thoughts on what might go well in here? I've had bourbon porters, but nothing else. Any thoughts on a good recipe/style of beer? Also I'm assuming you'd do secondary on this?
I've read some about evaporation(I know that bourbon definitely evaporates) but what about with beer since I'd be keeping it at a controlled temp unlike aging whiskey should I keep DME on hand to top it off?
