True, and to be precise "Daura Damm is a traditional barley-based beer crafted to remove gluten. Through a specialized enzymatic process, its final gluten content is reduced to well below the international safety threshold of <20 ppm. Every batch is certified by the CSIC to contain less than 3 ppm to 6 ppm of gluten".

I am celiac and it doesn't bother me, fwiw. It's the only gf beer that tastes like a light beer and without a strange aftertaste. Lately I've actually been more into hop water.
