Why Does My Wine Taste Like Vinegar Part Two

So you are here because you have made a very bad batch of wine and want to know exactly what went wrong. There is a long answer, but I’ll start with the short one. You did not properly sterilize your equipment. What that means is that there were some bacterias that were infesting your brew and destroying things that did not need to be destroyed.

There is also the chance that you kept your wine in a warm place while you were aging it. The could happen if you kept your wine near a water boiler in the basement or some place like that. Now in the off chance that you bought some cheap wine and didn't go through the whole process of making you own, the supermarket probably stored it wrong. If this is the case, as soon as you pop the cork or screw off the top, the bacteria will go into overdrive and just ruin your wine.

But wait, there's more. You could have fermented you wine too long and let some air get in the bottle. This can be caused by not sealing the bottle properly. Another thing that can cause this is by not properly choosing the right vessel for storing your wine. If you chose plastic then you are making a terrible mistake. Plastic is more porous than glass and will let air in right through the wall of the bottle if it is left for too long.
