A notable percentage of people have some motivation to reduce or completely eliminate gluten intake. Reasons vary from dietary choice to gluten sensitivity to serious medical conditions including auto-immune diseases like Celiac Disease. This may describe you or a friend or family member.
Recently Gluten Free Watchdog tested gluten content of a pitch of White Labs Liquid Yeast. White Labs does not mark their yeast gluten free. However they do say that yeast slurry in the package is below 20 ppm (their analysis is 12 ppm). Under 20 ppm is considered gluten free, although some products (like yeast made with malted, could not legally be labeled gluten free in the US).
Gluten Free Watchdog, found “well above 20 parts per million”
