This link claims that yeast contains gluten, which is understandable.
Yet today, a lot of people have a reaction to gluten that they are trying to avoid by becoming gluten-free. There are many brands of bread that sell gluten-free bread, made out of gluten-free grain.
When making my own bread, I want to use gluten-free yeast (and ideally, organic). These people sell organic quinoa yeast, which is gluten-free, but do not ship to the USA.
I am wondering what alternative exists that is gluten-free and organic and that one can find here in the USA.
