Many of the fermented and hydrolysed foods eg cheese, plain yogurt, white wine vinegar, cider vinegar are made from ingredients that do not contain gluten and are suitable for a gluten free diet. It’s always best practice to check that no ingredients containing gluten have been added to these products.

Products made from gluten containing cereals (wheat, barley, rye) which have been fermented or hydrolysed such as beer, soy sauce are only suitable for a gluten free diet if they have been processed to remove gluten, have been tested to be 20 ppm or less of gluten and are labelled gluten free. The products made from gluten containing cereals must also have on their label the statement ‘contains wheat/barley/rye’ as appropriate so they can be distinguished from those made with naturally gluten free ingredients. While we find answers, you can make a choice that is right for you by using the label to see what is in the product and make a choice on whether you want to consume it.
