Wine goes bad after opening

Shelf life: can wine go bad?

It is said that wine just gets better with age. But that no longer applies to most wines. Most of them are made in such a way that they have to be drunk young. But how quickly does wine go bad and what is the best way to store it? We'll enlighten you.

Many people wonder how long wine can actually be kept and whether it can go bad. Wine is not given a best-before date, as this is not an obligation for drinks with more than ten percent alcohol. But how do you know if the wine is still good? It is not possible to make a general statement about this, because how long a wine can be kept depends on many different factors.

Does a good wine go bad? Does white or red wine have a longer shelf life? How do you know if the wine is bad? What do you have to consider when storing wine? We will try to answer all of the questions for you.

How long does wine last?

When it comes to the question of how long wine lasts, a fundamental distinction must be made between closed and opened wines. Closed wines obviously have a longer shelf life, but how long are they exactly and what does that depend on? How long a wine can be kept depends on the alcohol content as well as the acid and sugar content, like that German Wine Institute writes. But the amount of sulfites and the quality of the cork also play a major role.

Closed wines - how do wines last particularly long?

  • The more acid a wine contains, the longer it can be kept. The acid in the wine ensures that the bacteria cannot grow so quickly, according to the blog "Noble droplets".
  • Alcohol acts as a preservative, that means wines with a high alcohol content last longer. If a wine has to be stored for a longer period, it should have an alcohol content between 12 and 13%.
  • The sugar content also plays a role in the shelf life. If a wine has a higher sugar content, the shelf life is extended. Auslese and Trockenbeerenauslesen therefore have a relatively long shelf life.
  • sulfite is contained in almost every wine. The fabric prevents oxidation and the post-fermentation of the wine.
  • The cork also plays an important role in durability. If the cork has a smooth surface, it is of good quality. If it is porous, it is of poor quality, which can lead to an unpleasant "cork taste".

Red wine lasts longer than white wine

But once the bottle open you expose the wine to its worst enemy: oxygen - and a gradual oxidation process begins, according to Frank Kämmer, one of Europe's leading sommeliers, on the blog FreshMAG.

Basically, the open wine should be drunk relatively quickly, because the wine loses a lot of taste or becomes even inedible. Drinking expired wine is certainly an uncomfortable experience, but it is unlikely to make you sick.

How do you recognize bad wine?

These are signs that your wine should be disposed of:

  • Your wine smells bad, for example musty.
  • If the wine has turned slightly brown, this is also a sign that it is no longer good.
  • If your wine is sparkling, meaning it is still sparkling, even though it shouldn't be, according to the label, it has already fermented for the second time. You shouldn't drink this wine again!
  • If the red wine tastes much sweeter than it should, then it is time to dispose of it.
  • If the cork is slightly pushed out of the bottle, this is a sign that the wine has overheated and has expanded in the bottle. You should also throw away the wine.

So that the unopened wine holds up well, it should be optimally stored. It is best to store the wine between 10 and 16 degrees without being exposed to large temperature fluctuations. In addition, you should always put the wine down when storing it, because this will keep the cork moist. With one already opened wine According to wine specialist Anke Kürschner, you should make sure to close it tightly and tightly and to store it in a dark refrigerator as she is on wein-konzept.de writes, because that makes the wine more durable.
