How long does it take beer to carbonate?

In this brief guide, we are going to answer the question “how long does it take beer to carbonate” with an in-depth analysis of the time it requires the beer to carbonate. Moreover, we are going to discuss what carbonation is and how beer is carbonated.

So without much ado, let’s dive in and figure out more about it.

How long does it take beer to carbonate?

The time which is needed by the beer to carbonate varies with the type of the beer but generally, it takes about 2-3 weeks for a bottled beer to carbonate. Thus, it is the time that is needed by the carbon dioxide to fully intermingle with the beer (carbon dioxide fully disintegrates into the beer) and gives that fizzy mouthfeel to it. Not only does the carbon dioxide gives a fizzy mouthfeel but it also enhances the flavor and aroma of the beer.

What is the carbonation of beer?

Carbonation is the process in which carbon dioxide is added to the beer to give it that fizzy mouthfeel. Not only carbonation is responsible for the fizzy mouthfeel, but it also enhances the overall flavor profile and the aroma of the beer. 

Now the amount of carbon dioxide that is added to the beer varies along with the type of beer. Generally, the carbon dioxide content of the beer ranges from 1.5 volumes of carbon dioxide up to 5 volumes of carbon dioxide. These are the two extreme values and mostly the carbon dioxide content of the beer falls in between these values. Most commonly the beers have a carbon dioxide content of about 2-3 volumes of carbon dioxide. It is worth mentioning that the “number of volumes of carbon dioxide” is the unit that is used to measure the carbonation.

If you want to find out which beer has more carbon dioxide added to it then you should look at the color of the beer. The lighter, hoppy beer has more carbon dioxide added to it while less carbon dioxide is present in a darker, maltier beer.,

So the question arises how do we carbonate the drink. To understand this thing you have to firstly look at the chemistry behind the beer production.

How is the beer carbonated?

Beer is one of the oldest and most commonly consumed beverages on the planet, and the third most famous beverage by and large after water and tea. Beer is fermented from oat grains—most ordinarily from barley, however, wheat, maize (corn), and rice are also used sometimes for the manufacture of beer. 

During the manufacturing process, fermentation of the starch sugars in the wort produces ethanol and carbonation in the subsequent beer and that is the key process that forms the backbone of the whole process.

In aerobic conditions (where oxygen is available), yeast transforms sugars into pyruvate. afterward, this pyruvate is further broken down into water and carbon dioxide. This is the process that is responsible for the carbonation of the beer. 

While talking about beer production at a commercial scale, the yeast works in anaerobic conditions to convert the pyruvate into ethanol. So in this process, there is no carbon dioxide production. The beer thus formed is carbonated with pressurized carbon dioxide afterward. 

So when the beer is poured down into a glass, the carbon dioxide that is disintegrated in the beer bubbles up and rises to the top of the beer along with the bubble formation. These large bubbles feed on many small bubbles on their way to the top and that’s why by the time they reach the surface, they form a thick foamy layer on it. This process is known as the Ostwald ripening. So in simple words, what happens is that as soon as the beer hits the glass surface, the carbon dioxide present in it releases and that very carbon dioxide is responsible for the foam formation. 

Moreover, when you transfer your beer from the cold bottle to the warm glass (room temperature), this temperature difference makes the carbon dioxide released at a faster pace, resulting in the formation of that smooth foam head.

What are the factors contributing to the mouthfeel of the beer?

Several factors contribute to the mouthfeel of the beer and each of them affects the mouthfeel and viscosity of the beer in its own way.

  1. Carbonation
  2. Body of the beer
  3. Creaminess
  4. The alcohol content of the beer
  5. Temperature

Conclusion

In this brief guide, we answered the question “how long does it take beer to carbonate” with an in-depth analysis of the time it requires the beer to carbonate. Moreover, we discussed what carbonation is and how beer is carbonated.
