Wine is a beloved beverage that has been enjoyed by people around the world for centuries. However, even the most experienced wine connoisseurs can be left disappointed when their favorite bottle of wine turns sour. But why does this happen?
This can happen due to a variety of reasons, such as exposure to air or improper storage. But don’t fret, as there are several ways to prevent wine from going bad after opening. In this comprehensive guide, we’ll take a closer look at why wine goes sour after opening and provide you with some practical tips to help you preserve the quality of your wine.
Why Does Wine Get Sour?
Oxidation
One of the main reasons why wine goes sour is due to oxidation. When a bottle of wine is opened, the wine is exposed to air which causes a chemical reaction that alters its flavor and aroma. This process is known as oxidation, and it can result in the wine taking on a sour or vinegar-like taste. Additionally, exposure to light and heat can also accelerate the oxidation process and lead to wine going sour.
Growth of Microbes
Another reason why wine can turn sour is due to the growth of bacteria and fungi in the wine. This can happen when the wine is not properly stored or when the bottle is not sealed tightly enough. The bacteria and fungi consume the sugars in the wine and produce acetic acid, which gives the wine its sour taste.
Type of wine
The type of wine has a significant impact on its ageing process and the possibility of it going bad. Some wines are meant to be consumed young, while others can age for decades, and the difference lies in the wine’s acidity, tannins, and sugar content.
For example, red wines that are high in tannins, like Cabernet Sauvignon or Syrah, can age for years, even decades, due to the tannins acting as a natural preservative. As these wines age, the tannins slowly soften, allowing for the wine’s other flavors to become more prominent.
In contrast, white wines and rosés that are lower in tannins and higher in acidity, like Pinot Grigio or Sauvignon Blanc, are best consumed young. Over time, the acidity in these wines can degrade, resulting in a flat and dull taste.
Additionally, the sugar content of wine can also impact its aging potential. Dessert wines, like Port or Sauternes, are made with higher sugar content, which acts as a natural preservative and allows them to age for decades.
How to Save Wine from Getting Bad?
If you are a wine lover, you know how important it is to store and serve wine correctly. Proper storage and serving can make a huge difference in the taste and quality of your wine. Here are some tips to save your wine and keep it tasting its best:
- Store your wine in a cool, dark place: Wine should be stored at a temperature between 45-65°F (7-18°C) in a dark place, away from light and heat sources. Exposure to light and heat can cause your wine to spoil and lose flavor.
- Store your wine horizontally: Wine bottles should be stored horizontally, with the cork facing down. This will keep the cork moist, preventing air from entering the bottle and spoiling the wine.
- Keep your wine away from strong odors: Wine can absorb strong odors from its environment, so it’s important to store it away from strong-smelling foods, chemicals, or cleaning products.
- Serve wine at the right temperature: Different types of wine have different ideal serving temperatures, so it’s important to know the optimal temperature for the wine you are serving. For example, red wine should be served at room temperature, while white wine should be served chilled.
- Use a wine preserver: If you don’t finish a bottle of wine, you can use a wine preserver to keep the wine fresh for a longer period. A wine preserver removes air from the bottle, preventing oxidation and spoiling.
By following these tips, you can ensure that your wine stays fresh and flavorful, enhancing your wine-drinking experience.
