As an expert sommelier and brewer, I can assure you that drinking spoiled wine is generally not going to make you sick. While there is a possibility that there may be foodborne pathogens present in a glass of bad wine, the chances of actually developing food poisoning from it are quite rare.
When wine goes bad, it typically becomes unpalatable rather than harmful. The taste and aroma of spoiled wine can be off-putting, often resembling vinegar or mold. This is usually a result of the wine being exposed to oxygen for an extended period of time, causing it to oxidize and deteriorate.
In terms of health risks, the alcohol content in wine acts as a natural preservative, making it difficult for harmful bacteria or pathogens to survive. Additionally, the acidic nature of wine creates an environment that is generally unfavorable for the growth of bacteria.
That being said, it is important to note that there are exceptions to every rule. If a wine has been contaminated with a significant amount of harmful bacteria or if it has been improperly stored in unsanitary conditions, there is a small chance that it could make you sick. However, instances like these are quite rare and unlikely to occur with commercially produced wines.
In my years of experience in the wine industry, I have come across my fair share of spoiled wines. While they may not pose a significant health risk, they certainly don't provide an enjoyable drinking experience. The flavors and aromas of spoiled wine can be extremely unpleasant and can ruin the overall enjoyment of the beverage.
While there is a slim possibility of encountering foodborne pathogens in spoiled wine, the likelihood of getting sick from drinking it is low. The main concern when it comes to spoiled wine is the unpleasant taste and aroma rather than any potential harm to your health. It is always recommended to trust your senses and avoid consuming wine that has clearly gone bad.
