Are Some Beers Actually Gluten-Free? This Research Says Otherwise
The breakdown of gluten isn't reliable
Colgrave says in her experiment that the enzymes used to get rid of gluten don’t seem to be working reliably. Across different brands of beers that have been made using an enzyme, the application seems inconsistent. Some beers have low amounts of gluten and are hardly detectable while other beers have as much gluten as an untreated beer.
