DOLCE VITA di LIBRO: HOW TO TELL IF WINE HAS GONE BAD
Any who enjoys wine has been in the position of trying to guess whether a bottle of wine has gone "bad". Is it a matter of "I'll know it when I experience it"? Or is wine that has "soured" actually a potential health risk? A large part of "living the good life" is learning about the best and that means weeding out the worst. Here are some ways to know if the wine you are considering drinking is not worth the effort:
1. Smell the wine for signs of oxidation, which occurs when air has gotten into a bottle of wine. Open bottles of wine that have not been stored properly can easily become oxidized and will smell pungent, like vinegar. This smell is easily recognizable once you've smelled it.
2. Look at the cork for signs of corked or corky wine problems. When wine is bottled, the natural cork used in bottling wine can sometimes get wet. If the cork gets wet, it can develop an invisible mold. When the moldy cork is then placed into the wine bottle, the mold actually goes into the wine itself. This will give the wine a musty or cardboard like odor. The wine may even smell like the cork itself.
3. Sniff the wine for a sulfur odor. Wine that has too much sulfur in it can smell like matchsticks or rotten eggs. Wine can have too much sulfur in it due to improper storage or because too much sulfur dioxide was added during the bottling process.
4. Check for signs of cooked wine. If wine is stored in warm or hot places such as attics, car trunks or near the stove, it can begin to "cook". Cooked wine will have a brownish tint when poured into a glass. It can also smell caramelized. Bottles of cooked wine may also have corks that appear pushed upwards and partially out of the wine bottle.
