Looking for some advise/council... I just discovered a bung blown off of a 15 gallon barrel. I filled those barrels a week ago. I checked them before I left on a business trip on Sunday, 6 days ago. The longest it could have been off the barrel is that amount of time. When I noticed it, there were a bunch of fruit flies buzzing around and had landed on the bung hold. I added a tablespoon of K-Meta and replaced the bung. Questions: 1. Is the wine ruined? So much for micro-oxygenation... 2. What about the fruit flies? Did they ruin the wine? 3. What do you suggest I do? 4. Do I have an award winner or a drain filler?
