Ingredients of Corona Beer

Barley malt

Barley malt is a vital ingredient in the production of Corona beer, greatly influencing its distinctive flavor. The process begins with soaking barley grains in water and letting them germinate.

Once sprouted, these grains are dried out and crushed to produce what is known as malt. This substance provides the necessary sugar for yeast to consume during fermentation, which eventually produces alcohol.

In Corona’s brewing process, only top-quality barley malt is used – contributing to its consistent refreshing taste that has helped cement Corona’s popularity globally as a leading Mexican import beer.


Corn is an important ingredient in the production of Corona beer. It plays a crucial role in adding flavor and body to this popular Mexican lager. Corn, also known as maize, is used alongside barley malt to create a unique blend of grains that give Corona its distinct taste.

The use of corn contributes to the light-bodied nature of the beer, making it refreshing and easy to drink. With each sip, you’ll enjoy a crisp and clean finish that perfectly complements the sunny beach vibes Corona is known for worldwide.

So kick back, relax, and savor the delightful combination of corn and barley malt in every bottle of Corona beer.


Hops are an integral ingredient in the production of Corona beer. Coming from the hop plant, hops contribute to both the flavor and aroma of this popular Mexican lager. They provide a pleasant bitterness that balances out the sweetness of the barley malt and corn used in brewing Corona beer.

Hops also add floral, citrus, and herbal notes to create a refreshing taste experience. With their unique characteristics, hops play a key role in defining the crisp and clean finish that Corona beer is known for worldwide.

So when you crack open a bottle of Corona, you can thank hops for adding that extra burst of flavor to your drinking experience.


Yeast plays a crucial role in the brewing process of Corona beer. It is responsible for fermentation, where it converts sugars into alcohol and carbon dioxide. This natural process gives Corona its distinct flavors and aroma.

Yeast is added to the beer during the brewing stage, where it feasts on the maltose created from barley malt and other grains like corn. The fermentation process can take several weeks, allowing the yeast to work its magic and create a flavorful and refreshing beer that we all know as Corona.

So next time you enjoy a bottle of Corona, raise your glass to this tiny but mighty microorganism that adds that special touch to your favorite Mexican lager!

Antioxidants (ascorbic acid)

Corona Beer contains antioxidants in the form of ascorbic acid. Ascorbic acid, also known as vitamin C, is a powerful antioxidant that helps protect our bodies from oxidative stress and free radicals.

While it may seem surprising to find antioxidants in beer, they are added during the brewing process to prevent oxidation and maintain the freshness of the beer. Antioxidants like ascorbic acid play an important role in preserving the quality and taste of Corona Beer, ensuring that every sip delivers a refreshing and enjoyable experience.

So, when you raise a glass of Corona, you not only get to savor its crisp flavor but also benefit from the presence of these beneficial antioxidants. Enjoy responsibly!

Propylene glycol alginate

Propylene glycol alginate is one of the ingredients that makes up Corona beer. It is a food-grade stabilizer and emulsifier derived from brown algae. This additive helps to maintain the foam stability and prevents any separation between the liquid and gas phases in the beer, leading to a smoother drinking experience.

It also enhances the overall texture and mouthfeel of Corona beer, contributing to its refreshing taste. Propylene glycol alginate is an approved ingredient by international food safety authorities and poses no harm when consumed in moderation.

So, next time you crack open a bottle of Corona, you can appreciate this interesting component that adds to its unique composition.

Use of rice and maize

Corona beer stands out from other beers due to its unique combination of ingredients. One notable aspect is the use of rice and maize in the brewing process. These grains contribute to Corona’s light-bodied and smooth taste, making it a popular choice among beer enthusiasts.

The addition of rice helps create a crisp and clean finish, while maize adds sweetness and depth to the flavor profile. This careful blend of ingredients, along with traditional brewing techniques, sets Corona apart as a refreshing Mexican lager that is enjoyed by people around the world.

Filtration through diatomaceous earth filter

Corona beer goes through a unique filtration process using a diatomaceous earth filter. Diatomaceous earth is a natural sedimentary rock that is finely ground into a powder and used as a filtering agent.

This method helps remove impurities and clarify the beer, resulting in its crisp and clean finish. It’s important to note that this filtration process is just one step in the overall brewing process of Corona beer, which combines quality ingredients like barley malt, corn, hops, yeast, antioxidants (ascorbic acid), and propylene glycol alginate.
