Wine grapes are gluten free, however, other ingredients and processes used during the winemaking process have the potential to contribute trace amounts of gluten to wine. These items may include yeast, fining agents, filters, barrel sealing materials and some packaging. Cooperages (barrel manufacturers) sometimes use a flour paste to seal the heads (ends) of the barrels used to age wine. While unlikely, it is possible that a minute amount of gluten may find its way into the wine from this source. There is also the slight possibility that gluten could be present in the packaging materials in which wines are shipped. We feel confident that our wines are safe for those with gluten intolerances, however our official recommendation is that individuals must decide for themselves if a product is right for them based on their own personal circumstances and advice from their doctor.
