After getting my daily gross of freecycle e-mails I ran across one where a guy was getting rid of some of his old brewing equipment and bottles. When I got there, he had about 150 quart bottles, 2 20 gallon fermenting buckets and then he gave me 2 8 gallon oak barrels that he keep filled with water when not in use. He was a wine guy and only had red wine in each of them. What is the best way to clean them out and get them ready to accept beer? How do I find out if there is anything funky growing on the inside? I was thinking possibly doing a robust porter with a friend and age it in them. I am also thinking of doing a lambic in one of them.
