Gluten Free Oat Milk Brands UK

Is oat milk typically gluten free?

Oats do not naturally contain gluten, HOWEVER, they are commonly grown and processed alongside gluten containing cereals and as such cannot always be classified as gluten free. If the oats used to make an oat milk have not been processed in isolation, then the oat milk will contain gluten. The list below explores which UK brands of oat milk are gluten free and which are not. You may be surprised how few are gluten free! Check out our complete guide on gluten in oat milk, or skip ahead in this article to see which brands are gluten free.

Gluten free vs. low gluten

An oat milk is deemed "gluten free" if it contains less than 20PPM (parts per million) of gluten. An oat milk is deemed "low gluten" if it contains between 20 and 100 PPM of gluten. Those wanting to minimise gluten should opt for certified gluten free oat milks.
