Good Question! For the most part, all our yeast is not gluten free. However, we occasionally will run a seasonal yeast strain that IS produced on 100% Gluten Free media. These strains will be differentiated by teal/blue packaging and will be clearly labeled, GLUTEN FREE.
For commercial brewers- we can grow any of our yeast strains on 100% gluten free media, please call us for information on order minimums and lead times.
