Hi, I bought this old (maybe ten years old) 15 gallon oak barrel as part of a bunch of wine stuff this guy in my area was selling. The barrel was in pretty rough shape, all the staves were loose, as were the rings. I decided to tighten up the rings and fill the barrel with water in hopes of swelling up the staves to see if it would hold water. After a few day, and continuing to flush it out it surprisingly started holding water. I drained it and put it on a rack I made to dry out. Now I smell this strong stench of vinegar coming from the barrel. I put the bung on it but can still smell it. Here's where my paranoia is kicking in; I have this barrel in my wine room and worried the vinegar will taint the wine I have bulk ageing in 5/6 gallon carboys. Are vinegar cultures an air born thing? I racked all seven carboys last weekend and now concerned with spoiling the wine. I think I might have used the same funnel during racking as I did to fill the barrel with water. I did wash and sanitize the funnel before racking. Should I be worried? Any thoughts????
