So a while back I was graciously given an empty Clément 5L (I think?) barrel by the owner of my favorite bar in DC when I told him about my idea to barrel up WN overproof.
He told me it'd need to be charred. So I took the hoops off closest to the head to open it up and take a look at it (maybe not a brilliant idea since getting it back together will take some effort, but that's neither here nor there).
Seems to me that is charred, or at least very heavily toasted, no? Or is that what a charred barrel looks like after something has been aged in it? Is that good enough to fill up with hot water to expand the wood, empty it out, then dump the rum in, or does it need re-charring?
