5 Most Common Wine Faults (and What Causes It)
Ever wondered why the waiter pours you a taster when opening a bottle of wine? This is not so you can decide whether you like it or not, but rather to determine any wine faults. We take a closer look at the 5 most common wine faults, what causes it and how to identify it.
Cork Taint (also known as corked wines or Trichloroanisole)
Ever opened a bottle of wine and it smelled like a wet dog, pungent mould, or wet cardboard? Chances are big that your bottle of preciousness has been affected by the fungi present in the cork. The fancy name for those fungi is Trichloroanisole, but colloquially it is referred to as cork taint or a corked wine (which is not a description for a wine closed with a natural cork, that is). The fungi find its way into your wine through several avenues, but the predominant cause is a faulty cork that is already contaminated with TCA. Regrettably, there is nothing you can do to eliminate TCA from a wine, and the best solution is to take it back to the supplier so that they can (hopefully) trace a spoiled batch. Alternatively, buy wines that are closed with screwcaps rather than natural cork. Not only will you get to the romance part of enjoying the wine quicker, but chances are slim that you will open a spoiled wine (and there is no chance of TCA).
