Clearing A 23-Year-Old Concord Wine

TroubleShooting

Q

I just opened a bottle from my stock of my homemade Concord wine that I bottled in 1992 and it was very cloudy. I checked others of the same year and they apparently are all the same. I have your Winemaker’s Answer Book, but can’t seem to find an answer to my problem as to how to clear them. I would like to clear and then re-bottle them.

Since 1992 (over 20 years) is quite a long time to store bottled wine. If you go to a supermarket or liquor store, you’ll notice that most red wines currently on the shelf date from 2013, 2012 or at the very oldest 2011. Yes, it’s true that American wine consumers don’t tend to age their wines but in a way it’s because most wines, except for the few truly exceptional pedigree vineyards around the world, peak after five years. If you’ve had good luck aging your Concord wines for that long, and still enjoy them, I applaud you. However, I have to think that your Concord home wine might have been better in the first 2-5 years of its life and not after 23 years in the bottle. It’s no surprise that after 23 years a homemade wine will throw some sediment or become cloudy, especially Concord, which is naturally high in pectin. This is a natural part of the wine aging process and can get more pronounced as the years go on. As to clearing and re-bottling the wine
