<<Disclaimer: Verify this information before applying it to your situation.>> Hello, Please bare with me I am new to this... gluten in vinegar ? I was under the impression Vinegar was GF , does this mean that mayonaise is not to be used or anything with vinegar may be suspect??? Tahnks, Debi, Alberta [log in to unmask] PS. Summary... Ethanol I received several replies to my question about Ethanol being GF Over all , it seems You MUST find out the Source of the Ethanol , if it is made from corn it is fine , but often it may be made from distilled grains. Ethanol is Ethyl Alcohol .. if it is pure it does not contain Gluten, again you must be guaranteed of "purity" *Without knowing the source it is best to stay away from products with Ethanol.
