When Did Beer Become Carbonated?

Beer has been enjoyed by humans for thousands of years, but when did it become carbonated? Carbonation in beer adds a delightful effervescence and enhances the overall drinking experience. In this article, we will delve into the history of carbonation in beer, explore the methods used to carbonate beer throughout the ages, and discuss its impact on the brewing process.

History of Carbonation in Beer

The origins of carbonation in beer can be traced back to ancient times. Early civilizations, such as the Sumerians and Egyptians, were brewing beer as early as 4000 BCE. However, these early beers were likely flat and lacked carbonation. It wasn't until much later in history that carbonation became a desirable characteristic in beer.

One significant development in the carbonation of beer occurred during the Middle Ages in Europe. Brewers discovered that by sealing beer in bottles, the carbon dioxide produced during fermentation would dissolve into the liquid, creating a natural carbonation. This discovery revolutionized the beer industry and led to the production of effervescent beers enjoyed by many.

Methods of Carbonation

Throughout history, brewers have employed various methods to carbonate their beers. Here are some notable techniques:

  1. Natural Carbonation: This method involves allowing the beer to naturally carbonate during fermentation. The carbon dioxide produced by yeast is trapped in the sealed container, resulting in carbonation. This is the traditional method used in bottle-conditioned beers.

  2. Forced Carbonation: In modern brewing, carbonation can be achieved through forced carbonation. Brewers introduce carbon dioxide directly into the beer under pressure, typically using a carbonation stone or a carbonation tank. This method allows for precise control over the carbonation levels.

  3. Krausening: Krausening is a traditional German technique where actively fermenting beer, known as "kräusen," is added to a finished beer. The active yeast in the kräusen ferments the remaining sugars, producing carbon dioxide and naturally carbonating the beer.

Impact on the Brewing Process

Carbonation plays a crucial role in the overall brewing process. It affects the mouthfeel, aroma, and flavor profile of the beer. Carbonation adds a refreshing and lively sensation to the beer, enhancing its drinkability. The level of carbonation can vary depending on the beer style, with some styles requiring higher or lower levels of carbonation to achieve the desired characteristics.

Controlling carbonation is essential for brewers to ensure consistency in their beer production. By carefully monitoring the carbonation levels, brewers can create beers that meet the expectations of their consumers and adhere to the style guidelines.


Carbonation has become an integral part of the beer-drinking experience. From ancient civilizations to modern brewing techniques, the desire for effervescent beer has shaped the way we enjoy this beloved beverage. Whether through natural carbonation, forced carbonation, or krausening, brewers have mastered the art of creating carbonated beers that delight the palate.

Frequently Asked Questions

Q: Can all beer styles be carbonated? A: Yes, carbonation can be applied to various beer styles, although the level of carbonation may vary depending on the style.

Q: How does carbonation affect the taste of beer? A: Carbonation adds a refreshing and lively sensation to beer, enhancing its drinkability. It can also influence the perception of flavors and aromas.

Q: Is carbonation necessary for beer? A: While not all beers require carbonation, it is a desirable characteristic for many styles, contributing to the overall enjoyment of the beer.

Q: Can I carbonate my homebrewed beer? A: Absolutely! Homebrewers can carbonate their beers using natural carbonation methods, such as bottle conditioning, or by employing forced carbonation techniques with the right equipment.

Q: How can I control the carbonation levels in my beer? A: Carbonation levels can be controlled by adjusting the amount of priming sugar or carbon dioxide added during the carbonation process. Precise measurements and calculations are crucial for achieving desired carbonation levels.

Remember, carbonation is just one aspect of the complex world of beer brewing. Exploring different carbonation methods and experimenting with carbonation levels can add a new dimension to your homebrewing journey. Cheers!
