The Science of Wine: Does Wine Go Bad after Opening?

Do you ever wonder if wine goes bad after opening? It’s a valid question, especially since opened wine doesn’t always last as long as unopened wine. In this blog post, we will explore the science of wine and answer the question once and for all! We’ll look at what happens to wine when it is opened, why it goes bad, and how to make it last longer. So pour yourself a glass of red or white and get ready to learn everything you need to know about the science of wine!

Does Wine Go Bad?

The Science of Wine and How It’s Made

Wine is made from grapes that are fermented with yeast. During fermentation, the yeast eats the sugars in the grapes and produces alcohol and carbon dioxide. Most of the carbon dioxide escapes, leaving behind the alcohol. Wine is typically around 11-13% alcohol by volume. Some higher alcohol wines are as strong as 20% alcohol by volume (ABV) or more, while others have a very mild ABV of 6% or less.

Wine spoilage is caused by bacteria that turn ethanol into acetic acid. This process is called oxidation and it’s what makes wine taste sour and vinegary. Oxidation occurs when wine is exposed to oxygen, so it’s important to keep wine sealed in a bottle or container with as little air exposure as possible. 

How to Store Wine Properly to Extend Its Lifespan

The first step to storing wine properly is to choose the right type of container. Keeping wine in the original glass bottle is ideal, but if you’re going to transfer it to another container, make sure it’s airtight.

Once you have your storage container, the next step is to find the right location for it. Wine should be stored in a cool, dark place like a wine cellar or closet. If you don’t have a cool, dark place to store your wine, you can keep it in the fridge. If it’s a wine that should be enjoyed at room temperature, make sure to take it out of the fridge at least 30 minutes before you plan on drinking it so that it has time to warm up.

If you follow these steps, your wine should be good for weeks, if not months! But there are a few things that can cause wine to go bad more quickly, so let’s take a look at those now.

Factors That Make Wine Age Quicker

Exposure to Heat

One of the enemies of wine is heat. Wine should be stored at a temperature of 55 degrees Fahrenheit or cooler. If it gets too hot, the wine will start to become less flavorful. So if you’re storing your wine in a warm place like on top of the fridge or near a radiator, it won’t last as long.

Exposure to Light

Light can also be damaging to wine. Wine should be stored in a dark place to prevent it from deteriorating. UV light is especially harmful to wine, so avoid storing your wine in direct sunlight.

Opening and Re-Closing the Bottle

Once you open a bottle of wine, it starts to oxidize and the flavor begins to change. This process is accelerated when the bottle is opened and closed multiple times, so it’s best to finish an open bottle within a few days. Of course, if you have a half-full bottle of wine that you want to save for later, there are a few things you can do to extend its lifespan.

How to Make Wine Last Longer

There are a few things you can do to make sure your wine lasts as long as possible after opening. First, transfer the wine into a smaller container like a carafe or decanter. This will expose less of the surface area of the wine to oxygen and slow down the oxidation process. Second, be sure to cork or use a stopper to seal the container tightly after each pour. This will also help keep oxygen out and preserve the quality of your wine. Finally, if you’re not going to finish the bottle in one sitting, consider storing it in the fridge. Cold temperatures slow down chemical reactions, so storing your wine in the fridge will help it last longer.

How to Tell If Wine Has Gone Bad

Even if you store your wine properly, there will come a time when it starts to go bad. There are a few telltale signs that your wine has gone bad. The first is a change in color. Wine will usually darken as it ages, but if you see a drastic change in color, that’s an indication that the wine has spoiled. The second is a change in flavor. If your wine tastes sour or vinegary, that’s a sign that it’s gone bad. Finally, if you see sediment in the bottom of the bottle or glass, that’s another indication that the wine has spoilage bacteria present and has gone bad.

If you notice any of these signs, it’s best to discard the wine. Drinking bad wine can cause an upset stomach, diarrhea, and vomiting. So it’s not worth the risk!

Now that you know how to store wine properly and how to tell if it has gone bad, you can enjoy your favorite bottle of RayLen wine without worry!
