I’ve had a 3L oak barrel for a good 25 years.Got it and used it for aging Brandy when I lived in Portugal. When we moved and family grew there was no cheap wine to distill nor was there time. So the barrel’s been empty for the last +20 years. Having heard that some manufactors of these small barrels use glue also made me hesitate to use it.
But since I want to use oak for my coming projects I decided to kick off the new year by dismantling it, to verify if the barrel was ligit or bad, and to fix it up for toasting and charring sticks from the individual staves.
I was happy to find no traces whatsoever of glue or foul play, except the head parts were held together by nails (not sure if that counts as foul play tbh), but the inside was full of Whiskey fungus, Baudonia Compniacensis, which I washed out with a steaming hot water scrub. Seems it comes with Brandy too…

Now the staves and the heads are drying on my kitchen table and the question is what I do now? My plan is to STR, sand, toast and rechar, but do I need to do some sanitization, deep cleaning, steel brush scrubbing, etc before I start sanding the staves? How should I sanitize the wood? What are your thoughts?
