is guinness beer gluten free

Guinness beer, the iconic Irish stout known for its dark color and distinct taste, has been a subject of debate among gluten-conscious individuals. So, is Guinness beer gluten free? Let’s dive into the details and find out.

The Ingredients of Guinness Beer

To understand if Guinness beer is gluten free, we need to analyze its ingredients. The basic ingredients commonly found in beer include water, malted barley, hops, and yeast. However, Guinness beer includes a unique ingredient called roasted unmalted barley, which gives it its characteristic taste and color.

While barley contains gluten, the brewing process can affect the gluten content in the final product. The key lies in how the beer is crafted and whether measures are taken to remove or reduce gluten.

Gluten Content in Guinness Beer

Guinness has acknowledged that its beers are not suitable for consumers with celiac disease due to the presence of gluten. However, they claim that their products are well below the gluten threshold deemed safe for most individuals with gluten sensitivity or intolerance.

Guinness beer undergoes a unique brewing process that includes fermentation, filtration, and pasteurization. These steps play a significant role in minimizing the gluten content of the final product. According to Guinness, their beers contain less than 20 parts per million (ppm) of gluten, which is the global standard for labeling a product as gluten free. This level is considered safe for most people with gluten-related disorders.

Gluten-Free Alternatives to Guinness Beer

For individuals with celiac disease or extreme gluten sensitivity, even minimal amounts of gluten can cause adverse reactions. In such cases, it is recommended to opt for beers that are specifically labeled as gluten free. Some popular gluten-free beer alternatives include:

  • Anheuser-Busch’s Redbridge
  • New Belgium’s Glutiny Pale Ale
  • Bard’s Tale Beer Company’s Bard’s Beer
  • Omission Beer’s Gluten-Free Lager
  • Green’s Gluten-Free Beers

Additional Considerations and Caution

While Guinness claims their beer is safe for most individuals with gluten sensitivity, it’s essential to consider individual tolerance levels and consult with a medical professional if necessary. Some people may still experience adverse effects from the gluten content in Guinness beer due to its unique brewing process or personal sensitivity. It’s always wise to proceed with caution and understand your own reactions when consuming any beer, including Guinness.


In conclusion, while Guinness beer is not entirely gluten free due to its use of barley, it does contain less than 20 ppm of gluten, which is considered safe for most individuals with gluten sensitivity or intolerance. However, for those with celiac disease or extreme gluten sensitivity, it is recommended to choose beers specifically labeled as gluten free to avoid any potential adverse reactions. As always, it’s important to listen to your body and consult with a healthcare professional if needed.
