Is Corona Beer Gluten-Free? Exploring the Controversy and the Science

Corona Beer Gluten

Are you one of those beer enthusiasts who’s also following a gluten-free diet? You might be wondering if Corona, one of the most popular beer brands in the world, is safe for you to consume. In recent years, there has been a lot of controversy surrounding Corona and its gluten content. In this article, we will explore the science behind the controversy and answer the question once and for all: Is Corona beer gluten-free?

What is Gluten?

Before we dive into the specifics of Corona beer, it’s essential to understand what gluten is. Gluten is a protein that is found in grains such as wheat, barley, and rye. It’s the substance that gives dough its elasticity and helps bread rise. Gluten is also commonly used as a thickener in many processed foods and drinks.

The Gluten-Free Diet

The gluten-free diet has become increasingly popular in recent years, especially among people who have celiac disease, gluten sensitivity, or wheat allergy. Celiac disease is an autoimmune disorder that affects the small intestine, and consuming gluten triggers an immune response that damages the lining of the small intestine. People with celiac disease must avoid all foods and drinks that contain gluten. Gluten sensitivity and wheat allergy, on the other hand, are not autoimmune disorders, but consuming gluten can cause uncomfortable symptoms such as bloating, abdominal pain, and diarrhea.

The Controversy Surrounding Corona Beer

Now that we know what gluten is and why people avoid it, let’s get back to the question at hand: Is Corona beer gluten-free? Corona is a brand of beer that is brewed in Mexico and is known for its light and refreshing taste. The controversy surrounding Corona beer and its gluten content began in 2017 when a lawsuit was filed against the brand. The lawsuit claimed that Corona contained gluten levels that exceeded the limit set by the FDA for gluten-free products.

The controversy was fueled by the fact that Corona is brewed with barley malt, which contains gluten. However, the brewing process involves several steps, including filtration and clarification, that remove most of the gluten. In 2018, a study published in the Journal of Food Composition and Analysis found that Corona Extra contained less than 20 parts per million (ppm) of gluten, which is the FDA’s threshold for gluten-free products. The study concluded that Corona beer can be considered gluten-free and safe for people with celiac disease or gluten sensitivity to consume.

The Science Behind Gluten Testing

If you’re still not convinced that Corona beer is safe for you to drink, it’s essential to understand the science behind gluten testing. Gluten testing is a complex process that involves extracting gluten from a food or drink sample and measuring its concentration. However, gluten testing is not always accurate, and there are several factors that can affect the results, such as the type of test used, the sample size, and the sample preparation method.

It’s also worth noting that the gluten content of beer can vary depending on several factors, such as the type of grain used, the brewing process, and the filtration and clarification methods. This means that different brands of beer can have different gluten levels, and even the same brand can have varying levels from batch to batch.


So, is Corona beer gluten-free? Based on the available scientific evidence, it’s safe to say that Corona beer can be considered gluten-free and is safe for people with celiac disease or gluten sensitivity to consume. However, it’s always essential to listen to your body and consult with a healthcare professional if you have any concerns.

Is Corona beer safe for people with celiac disease?

Yes, Corona beer can be considered gluten-free and is safe for people with celiac disease to consume.
