The process by which Omission Beer removes all gluten

Press Release:

(Portland, OR) – Omission Beer, introduced by Craft Brew Alliance (CBA) in March, is sharing additional details about the brewing program that allows Omission Lager and Omission Pale Ale to be brewed using traditional ingredients, like malted barley, but without the gluten-levels associated with other malted barley-based beers. Every batch of gluten-free Omission beer, which is only available in Oregon, is brewed following the multi-stage program developed by the brewery, and every batch is tested by an independent lab to ensure that it contains gluten levels well below the international gluten-free standard of 20ppm or less. This standard is defined by the United Nations Food & Agricultural Organization and the World Health Organization.

Brewed by Widmer Brothers Brewing in Portland, Ore., Omission beers have turned heads in the craft beer industry, celiac community and beyond. Committed to educating consumers about the beers brewed under the Omission brand, CBA is offering greater insight into the proprietary brewing process behind the beers that everyone of legal drinking age can enjoy.

“We’ve had a great response to our new line of Omission beers and, naturally, a lot of questions about our approach,” said Terry Michaelson, CEO of CBA. “After a significant investment in research, testing and development over the past two years, we’ve established an entire brewing program focused on managing gluten in the brewing process from start to finish.”

The Omission brewing program includes additional steps and requires additional care, beyond standard brewing practices and protocols, to ensure that beer brewed with malted barley meets strict gluten standards set forth by the brewery:

— Ingredient and style selection: Omission beers are brewed with low-protein barley. Style choices are based, in part, on ability to reliably reduce gluten-levels to well below strict standards.

— Sanitization: All brewing equipment downstream from fermentation is freshly cleaned and sanitized for every batch of Omission beer. Unlike the process used in brewing other beers, where hot water rinse may be sufficient, equipment is cleaned and sanitized before Omission beers are brewed to avoid risk of cross contamination.

— Brewers Clarex(TM): Brewers Clarex(TM), an enzyme developed by DSM Food Specialties and traditionally used to prevent chill-haze in beers, is added during the brewing process. The enzyme, which has been used by craft brewers around the world as a clarifying agent since it was introduced more than five years ago, works to break down proteins, including gluten, in the beer.

— Testing: Every batch of Omission beer is tested for gluten by two independent labs using the R5 Competitive ELISA. Omission beer’s primary lab partner is Eurofins Scientific, the world leader in food and pharmaceutical products testing. Every batch of Omission beer is also tested by the Food Allergy Research and Resource Program (FARRP) at the University of Nebraska. Tests are also conducted internally by the brewery at various stages in the brewing and packaging processes; within a month, Omission beers will be tested internally at the brewery using the R5 Competitive ELISA as well. No bottles of Omission are released to consumers until all results are reviewed and verified to contain gluten levels well below the international gluten-free standard of 20ppm or less.

— Packaging: To further protect the integrity of the beers, Omission beers are only sold in bottles and never available on draught, where risk of cross contamination from tap lines or server error could threaten consumer safety.

— Consumer Education: CBA is committed to sharing information about the beers, brewing processes and testing so consumers can make a confident choice when purchasing and drinking Omission beer. Consumers are encouraged to visit , where they can enter the date code stamped on their bottle and view their beer’s R5 competitive ELISA test results.

“Developing a brewing program that would allow us to brew great tasting craft beer brewed with malted barley, but happens to be gluten-free, has been a personal mission of mine for the last several years,” said Joe Casey, brewmaster at Widmer Brothers Brewing. “With the Omission program, we’re able to consistently brew beer with gluten levels well below the international gluten-free standard.”

  1. I have researched GF beers for years, and I notice you are using European standards for gluten free, not 100% GF.
    Recently, I had a GF Buckwheat Pale Ale that was 100% gluten free & orangic. 7 Bridges Brew Organic in Santa Cruz, CA., introduced it as a new home brew kit at the Hops & Barley Festival in Scotts Valley. The kit will have the option of using malted buckwheat or malting your own….recipe is free.

  4. Sorry but Omission beer is not yet labeled as gluten free. It’s great that the standards have been created but as of now the Elisa test for whole gluten protein that Omission uses has not been shown to work on gluten fragments.

    I.e., If the gluten fragment contains an intact binding site for human antibodies then GF people will still get a reaction regardless of whether the Elisa test detected whole gluten or not.

    It might also be that, if the enzyme itself degrades more quickly than the gluten fragments, then the gluten fragments could bind back together and become whole gluten protein sitting in the bottle on the shelf! This is just one example of basic research that needs to be done.

    When Omission can do the basic research then I’ll enjoy it.

  7. Thank you Omission for making great tasting beer that has enough reduction in gluten that I can drink them without getting my gluten reaction. – My personal gold standard.
