How long can you keep home made wine for?!
Answers: I have a bottle from 1985 is it too old to drink?
It depends on several factors.
What type of wine? General rule, darker will last longer. Some lighter bodied and colored wines just aren't designed to last that long, even commercial wine.
In what conditions was it kept? Heat or leaving the bottle upright so the cork dries out can hurt the taste.
How fastidious/successful was the vintner in sanitizing everything? If the bottle wasn’t super clean to begin with, the wine will be bad in just a few weeks
I would suggest opening it up and trying it. Nothing that can kill you can survive in the alcoholic environment of wine (or beer). If it tastes good, enjoy it. If it's bad, pour it out and get a new bottle to drown your miseries.
