Bulk aging carboy bung came off. Time frame IDK

[jhawk]

Went down stairs tonight and notice that one of my red wine bulk aging carboys with a bung popped out. I don't know how long it has been out. It's been bulk aging since April. What's the chance of this wine is now ruined?

Taste it. It is probably ok. Give it a dose of K-Meta, and put the bung back on.

Just a guess: assuming the bung popped off because of pressure from gas in the wine, that gas is CO2. The CO2 is heavier than air and should protect the wine for a period, but not indefinitely. In the short term, I'd put the bung back on but with an airlock.

I agree. I've had it happen a couple of times. Sometimes it is a bit of co2 still working out, others just temperature. When I cold stabilize, I've taken to air locks as it warms up, even though fermentation is done, just so I don't have to worry about bungs launched around the winery.
