Why is tat my vintage wine went sour?!
Answers: I bought it, let it sat in room temperature. The day I opened it, it went very sour why is that? It got worst over 3 days. How do you buy good vintage wine? How do you store them?
You should immediately check the cork when you find that. If it has dried out, then air got to the wine and it spoiled. If it is still moist, then the problem was not due to your storing it. You didn't say how you let it sit, or for how long, but if you had it upright for a couple of weeks, then the cork will dry an you'll lose the seal.
If stored correctly and the cork was still moist - or wine even leaking to the top - there was probably a problem with the cork. One thing that can happen is that the bottle manufacturer did not maintain their equipment and a few of the bottles come out slightly larger at the neck and the cork does not seal tight. In that case you can take the bottle back to the winery (a wine store should take it back).
If the wine tastes bad, as opposed to outright sour, the cork may have had a fungus. Wine people say the wine "was corked". Its getting more common as the worldwide supply of good cork is declining. Corked wine can also be taken back to the winery.
Wine goes sour usually when it is over aged or the cork (or whatever seals the bottle) has failed in some way.
Wine continues to age in the bottle and thus most modern wines have a limited shelf life. It is supposed to be kept at a constant temperature and humidity for the sake of the contents and the thealth of the cork. This is why cellaring is undertaken. I won't give you all the correct storage details, they are easy enough to find on the net.
The most likely cause of your wine being sour is that the cork failed. It is the reason why so many wine makers are switching to screw tops for even their most prestigious wines because cork failures cost the industry and consumers millions avery year in spoiled wine. One thing which readily leads to cork spoilage is the wine bottle has been stored upright and not on its side. This allows the cork to dry out and can cause the seal to break allowing air into the bottle.
i dont know about wine but why does vintage beer go bad
Always store wine in a cool, dark place on their side. The refrigerator is too cold for reds, but is fine for whites you are going to consume within a couple days. A cabinet, away from the stove and refrigerator, is good as it lets them be on their side. An actual wine cellar (<$100 for small ones) is pretty much perfect.
Once opened, you have a couple days to use it. I prefer to recork the bottle and put it in the fridge. It will slow the oxidation rate, preserving the wine a little bit more. For reds, take out 30 minutes before serving to come up to temperature, it's that simple. If you have a half bottle left and old, cleaned 375mL bottles, consider moving the wine into these small bottles. The decreased air will dramatically slow down oxidation -- if the wine is very close to the cork you can actually store it in the cabinet again.
Sometimes you can't avoid it, but the cork is faulty. It gets dried out, or wasn't tight enough/cracked. Air gets in, and your wine oxidizes, giving you sour wine.
Also important: Most wines are not meant to be stored more than 5 years. For some of them, this is too long (pinots -- red or white). The only ones that benefit by a prolonged aging tend to be the full bodied reds -- Cabernet Sauvignon the prime example. Even here, 10 years is more than most can handle.
well hello eee! wine is like a kiss, if you don't use it, you loose it ! sounds like maybe the bottle was not sealed all the way ? wine is usually better the older it is ! have you tried Lambrusco.... yummy !!! later, butcher......
some times , but not too often , the cork will not seal correctly and allow out-side air into the bottle , thus introducing air-borne contaminants to the wine and it will then `sour` or spoil.
not all corks are 100% tight......you were just un-lucky in this case..!
best storage advice is to lay the bottle on its side , so that the wine can keep the cork "wet" (creates a better and air-tight seal) , this can be done by buying a wine stand from any good retailer or Liquor out-let.
store wine in a cool , dark space away from too much heat.
temp. = around 10-18 degrees Celsius.
place = possibly in your food cupboard(pantry) at the bottom , near the floor.
"standing" the bottle at room temp. is only required to be done BEFORE opening and serving the wine..!
good luck in the future with your wine purchases and i would consider returning to the out-let that sold you the wine and see if they can come to some sort of refund or ex-change for you.....after all , if they don`t know there may be a problem with that particular Batch of wine , neither they or the Maker can do any-thing to correct it .... !
don`t scream at the retailer , he didn`t make the wine. Ciao.
