I found someone that has a pile of used wine barrel oak slats and inserts (wood pieces in the barrel). It his scrap pieces but he is a junk seller so since I want them they are not free. He told be to make an offer. He has about two barrels full of 8" pieces. Most wear red wine. I know oak is good and being aged w/ red wine can not hurt so what do think i should offer him for the pile?
