Looking perfect thus far.
I see more of these barrel builds coming in the future, being refined each time.
I have absolutely no use for it, but if I come across a barrel cheap I won't be able to resist building one.
EDIT: Check with your local wineries for barrels. Once all the flavor has been leeched out of the wood, they aren't of use to them anymore.
My girlfriend will be excited to go wine tasting. She doesn't need to know why.
