How to tell if wine has gone bad

The production of wine is very sophisticated. The production of a bottle of valuable wine requires the right time, right place and right people. Any deviation in any link will make the wine taste bad. So how do we judge whether the wine has gone bad?

How to tell if wine has gone bad

1. Determine the oxidation phenomenon of wine deterioration

Wine, like metals, will oxidize, especially when too much air enters the wine, which is more likely to cause oxidation. This is also a common reason for wine to go bad. Oxidized wine will become darker red, and the original bright red will become brownish red, and it will have no luster. The taste is very bitter. There is no way to remedy oxidized wine, it can only be discarded.

2. Determine the cork contamination phenomenon of wine deterioration

Cork taint refers to the deterioration of the cork, which causes the wine in the bottle or oak barrel to deteriorate. Cork-tainted wine will have a cork-like damp smell, such as a damp and moldy smell. This is the second largest factor in wine deterioration. There is no remedy for wine that has deteriorated due to cork taint.

3. Determining the sulfide contamination of wine spoilage

Sulfur dioxide and other sulfides need to be added during the wine production process to prevent the wine from being contaminated by other factors. However, excessive addition of sulfur dioxide will damage the wine and give it a pungent smell.
