Drinking wine is one of the most enjoyable experiences. But, when you sip a glass of wine and find out that it has gone bad, it can be one of the most annoying situations and of course money wasted. And what makes this situation even worse, is when the bottle of wine is an expensive one or a vintage. For example, "Chardonnay white wine that you have been saving for long for a special occasion." Fortunately, there is way do discover if the wine has gone bad before you drink it by performing the 'smell test'. This will allow to pick up on whether the wine has gone off before you drink it. Wine Gone Bad Smells There is more than one distinct smell that can indicate that there is a fault in the wine and it is not worth to try. Below are some of the smells of a wine that is off. 1. Rotten eggs, cowpats or sewer That means that a bi-product of the wine yeast fermenting sugars called hydrogen sulfide didn't get the needed nitrogen as it metabolize the sugars into alcohol. The result is very unpleasant aromas. 2. Skunk, cat pee or burnt matches The culprit of these smells are the mercaptans. Mercaptans are a group of smelly mixtures that are created by hydrogen sulfide. When exposed to oxygen, they lead terrifying smells. 3. Wet moldy cardboard or musty This aroma happens when wood fungi comes into contact with the cork. Wood fungi occurs naturally and as they metabolize, the mixtures produced in the wine bottle give off this fault. 4. Vinegar smell and taste Caused by a little bacteria called Acetobacter. It is responsible to metabolize the ethanol in the presence of oxygen. Vinegar are produced in this way. 5. Dry straw or bruised apples This happens when ethanol becomes oxidized. It can happens during the winemaking process where ethanol is present and exposed to oxygen - or when fermentation happens and ethanol is make right up to bottling. So, if you smell applesherry aroma in the wine that means it was left in the air for too long.
