I made a 5 gallon batch of blueberry wine late last year.
Arround Christmas, I filled a few bottles. There is still 3+ gallons in the glass carboy.
Last night, I noticed the water/starsan in the airlock was gone. Could have been gone for months. I have not tasted it yet.
Is the wine likely ruined? Stale? something else?
I guess I should taste it, but just wondering what has transpired.
