Is wine gluten-free?

While many items on the menu might trigger your gluten sensors, you can comfortably enjoy most wines without worry. So, yes, the vast majority of wines are gluten-free. Why is this the case? This is because the primary ingredients used in the fermentation process of wines are grapes, yeast, and sometimes sugar, none of which contain gluten. However, always be sure to check the label if you are particularly sensitive, as some wine producers may use gluten-containing additives or fining agents.
