01/18/2022 - Pretty much every gluten-free beer drinker wants the same thing: a really good beer that just happens to be gluten-free. That may soon become a common thing, if new research has anything to say about the matter.
Compared with traditionally brewed beers, gluten-free beers often have an inferior taste and body because they are produced using syrups and sugars introduced during the mashing process. Imparting flavor on gluten-free beers is challenging in the absence of barley malt, which contains key enzymes used to make traditional beers.

Producing gluten-free beer from gluten-free malts is challenging because gluten-free malts have lower enzyme activities, points out researcher Darrell Cockburn, assistant professor of food science in the College of Agricultural Sciences. A new mashing process could help to change that.
Cockburn and colleagues at Penn State University, including Ryan Elias, professor and associate head of food science, and Helene Hopfer, Rasmussen Career Development Professor in Food Science, have developed a modified brewing procedure using gluten-free malts and lower temperatures to retain enzyme activity, and produce high fermentable sugar concentrations. The process, called the "ExGM Decoction Mashing Procedure" uses malts from gluten-free grains to produce high-quality beers.
The process will help brewers using gluten-free grains such as teff, sorghum, rice, millet, corn and buckwheat to produce better-tasting gluten-free beers. By showing that gluten-free grains can produce quality beers, the researchers hope that brewers will use their process to craft higher-quality gluten-free products.
Could a simple adjustment to the malting process and temperature lead to major improvements in gluten-free beer quality? It's an exciting prospect. Stay tuned for more on this and related stories.
