Tl;dr- got an extraordinary amount of 20-year-old wine from an old dead guy. Rather than see it go down the drain, I figured I might be able to doctor it. It's still wine, but he didn't rack enough so it has off flavors. Looking for things to do with it or ways to fix it.
Near where I live, a family was moving and they were finally clearing out their grandfather's wine room. Apparently he died 15 years ago, much of the things in this picture were marked 2000. All of it was covered with a thick layer of soot and mold which I have now scrubbed off.
He was not a particularly good winemaker, as I don't think he was making wine for the long term, he was just making things to drink. Clearly wasn't racking enough. That being said, I did find campden tablets in his stuff so I figured if it was sealed and full, it might still be drinkable. The family assumed everything turned to vinegar because they weren't really read on the topic. Also because they probably tasted wine from the giant demijon that he likely used to siphon bottles from every so often when he wanted a bottle of wine so it just had a ton of headspace constantly. Out of curiosity, I took all the wine other than the giant 54 l demijons.
So far I've only tried the white wine in the 5 gallon carboy which looks like he never racked again. It is wine, it's not vinegar. Is it great wine? No. The perfume has obviously faded, and I think so much extended contact with the lees has led to autolysis, leading to a somewhat... Meaty taste in the wine. That being said, it is a balanced wine. Tartness and tannins were where they should be.
I'm going to tackle them one at a time, but I think this is rescuable.
My thought process for the 5 gallons is to add back what is gone. If it's lacking perfume, why not add some? If I make fruit wine coolers, or vermouth, or bottled mulled wine, I might be able to cover its emptiness. Sugar itself would probably do a lot of work. Wine coolers might be especially smart since they dilute and add carbonation.
The bigger concern is the meaty note. I think first order of operations would be racking it obviously, and then hitting it with some sort of fining agent. Probably sparkaloid. I bet that by itself will do a world of good. Once I have the neutral wine base, I can do things with it. If anyone has a strong suggestion on how to get rid of that extended Lee's contact note, I'm all ears.
A lot of these wines are named grapes, and he had a crusher and the juicer so he was doing that part holistically. I don't know if all of these wines will be good, if any are actually vinegar though probably reduce them into homemade balsamic. On the whole though, I think there's a lot of value here if I play my cards right.
If anyone has any other strong suggestions other than drinking, I'm willing to listen. It's a lot of wine.
