Is vinegar gluten free? One of our readers recently sent us this exact question, so I think it is likely that there are others out there who are also wondering the same thing.
Is vinegar safe to eat for people with Celiac Disease? The answer is yes…for the most part! Like most ingredients, vinegar is naturally gluten free, as the gluten it is made with is lost in the distillation process (just like alcohol).
While checking for additional information, I found this post by Dr. Stephen Wangen which goes into greater detail:
Other vinegars, such as red wine vinegar, apple cider vinegar, and balsamic vinegar also do not contain gluten. They are not derived from a gluten grain, therefore they never had gluten to begin with.
The primary exception to all of this is malt vinegar. “Malt” can almost always be assumed to mean “barley malt.” Barley is of course a gluten grain, and malt vinegar is generally not a distilled vinegar. Therefore there is gluten in malt vinegar. The other exception is when malt has been added into something after it has been distilled. This is sometimes the case with hard alcohols, but you have to check with the manufacturer.
Hopefully that clears up any potential confusion!
