Is Beer Carbonated?

Beer is often served at room temperature or chilled, but some beers are naturally carbonated. What exactly makes them carbonated?

Beer And Carbonation: What Does It Mean? 

Beer contains bubbles because of the carbon dioxide gas that comes from fermentation.

The carbonation gives the drink its fizzy taste. Other carbonated drinks include soda and sparkling water.

Carbon dioxide is produced during the fermentation process. This gas is trapped inside the liquid and creates tiny bubbles.

When the beverage is poured into a glass, these bubbles rise to the surface. They make the beverage look foamy.

When you pour a bottle of beer, the carbon dioxide escapes through small holes in the cap.

These holes allow the gas to escape as quickly as possible. If the cap had no holes, the pressure would build up until the container bursts.

When the beer is poured into a glass or cup, the carbon dioxide dissolves into the liquid.

As the bubbles dissolve, they release their carbon dioxide again. This causes the foam on top of the beer to disappear.

How Do You Make Beer Carbonated? 

You can add carbon dioxide to your favorite beer by using an airlock. An airlock allows oxygen to enter the container while preventing carbon dioxide from escaping.

An airlock consists of two parts: a rubber stopper and a plastic tube with a hole in it. Put the stopper over the opening of a bottle.

Then put the tube over the stopper so that there’s only one way for air to come out.

Fill the tube with water. Place the bottle next to the tube. Air will be able to get into the bottle, but the carbon dioxide won’t be able to leave.

The air will push the stopper down against the bottleneck. As long as the stopper stays down, the beer in the bottle will stay carbonated.

The amount of time it takes for the beer to lose its carbonation depends on how much carbon dioxide has been added.

A good rule of thumb is that if you wait 24 hours after adding carbon dioxide before drinking the beer, then the carbonation should last about 2 weeks.

If you want to keep your beer carbonated longer than this, you can use a CO2 tank. But don’t forget to turn off the tap when you’re done!

Is Carbonated Beer Bad For You? 

Some people think that carbonated beverages are bad for you. They say that the bubbles cause stomach problems.

However, most experts agree that carbonated beverages aren’t harmful.

In fact, many people enjoy carbonated drinks. Some people like the fizziness, others love the bubbly feeling. Either way, carbonated beverages are safe.

Why Is Beer Carbonated? 

There are several reasons why beer is carbonated. First, carbon dioxide helps preserve the flavor of the beer.

Second, carbonation keeps the beer cold. Finally, carbonation helps prevent the beer from spoiling.

Preserving Flavor

One reason that beer is carbonated is to help preserve the flavors of the ingredients used in brewing.

The yeast produces alcohol and other compounds that give beer its distinctive taste.

These chemicals are kept in suspension by the carbon dioxide. Without them, the beer would start to spoil.

Keeping Cold

Another reason that beer is carbonated is to keep it cool. Most beers have a specific temperature range where they work best.

If the temperature gets too high, the yeast stops working and the beer becomes flat.

Carbonation also helps keep the beer cold. It creates tiny bubbles that surround the surface of the liquid. These bubbles trap heat and make the beer feel colder.

Preventing Spoilage

Finally, carbonation prevents beer from spoiling. In order to do this, the carbon dioxide must escape from the solution.

To do this, the carbonation process releases some of the gas back into the atmosphere.

This means that the carbon dioxide doesn’t just stay in the beer. Instead, it goes back into the air. This makes sure that no bacteria can grow in the beer.

How Does Beer Get Its Carbonation? 

Beer is made by fermenting barley or wheat malt. During fermentation, enzymes break down the starches inside the grain. The result is sugar.

When the sugar comes in contact with yeast cells, it starts producing alcohol and other organic acids.

The yeast cells produce more enzymes to convert these acids into carbon dioxide.

As soon as the yeast dies, the carbon dioxide escapes through the holes in the bottom of the container.

Then, the pressure builds up until it’s strong enough to force the headspace above the beer out through the top of the bottle.

What Happens When I Drink My Beer? 

The first thing that happens when you drink your beer is that the carbon dioxide pushes against the walls of your mouth.

As the gas moves around your mouth, it causes a slight foaming effect.

This foaming action helps wash away any residue left behind after you’ve eaten.

Next, the carbon dioxide enters your stomach. Your stomach acid breaks down the carbon dioxide so that it can be absorbed into your bloodstream.

After that, the carbon dioxide travels throughout your body. It ends up in your stomach, which then tries its best to expel it in the form of burps.

If you’re drinking a lot of beer, your liver will eventually absorb all the extra carbon dioxide. 

What About Alcohol Content? 

Many people worry that alcohol content might increase with carbonation. However, this isn’t true.

Carbonating doesn’t change the alcohol content. In fact, some flat brews have more alcohol than carbonated ones.

There are, however, some studies that suggest that carbonation may affect how we process the alcohol in beer once the drink is down the hatch.

Results seem to show that carbonation hastens alcohol absorption, so bear that in mind next time you’re ordering your fifth jar of suds at the bar.

Final Thoughts 

Whether you like your beer sweet, bitter, sour, or even alcoholic, there’s a good chance that you’ll enjoy it better with carbonation.

And, for those who don’t want their beer to get fizzy, there are plenty of ways to stop the carbonation process.

So, next time you pour yourself a glass of beer, take a moment to think about how carbonation affects your beverage!

Hi, I’m Andrew Carr and I find beer fascinating. Not just drinking it (although that is a plus!) but everything about it. There is so much to learn - the fermenting process, the best glasses for each type, recipes to make at home… The list goes on!

I have been making my own beer for almost a decade now and I pride myself on my home setup. I’ve made sours, pale IPAs, stouts - you name it, I’ve probably made it in the comfort of my own home.
