Following a strict gluten-free diet can be both challenging and time-consuming. Whether due to celiac disease or non-celiac gluten sensitivity, mastering the art of label reading is essential. While most food products are required to provide detailed nutritional and ingredient information, the labeling requirements for alcoholic beverages can be less clear.

Beer, known for its cereal grain base, is off-limits for those avoiding gluten. But what about wine? To clarify, we consulted industry experts to determine whether wine is truly gluten-free, offering peace of mind for those with dietary restrictions. According to the FDA, for a product to be labeled gluten-free, it must contain less than 20 parts per million of gluten—equivalent to less than 0.002% gluten. Tricia Thompson, M.S., R.D., founder of Gluten Free Watchdog, which tests products for gluten levels through Bia Diagnostics in Vermont, confirms that wine typically meets these standards. She notes that wine, made from grapes and yeast—both naturally gluten-free ingredients—is generally considered gluten-free, though there are some nuances to be aware of.

The Risk of Cross-Contamination

Determining whether wine is truly gluten-free can be more complicated than it seems. While the primary ingredients in wine—grapes and yeast—are naturally gluten-free, there is always a risk of cross-contamination. This occurs when gluten or other microorganisms are unintentionally transferred during production, potentially affecting the wine’s purity.

One area of concern is the fining process, used to clarify and stabilize wine by removing unwanted particles. Depending on the fining agents used, such as chitosan or pea protein in the U.S., or egg whites and gelatin in other countries, there could be a risk of gluten exposure, though these agents are generally considered gluten-free. Furthermore, wines aged in oak barrels may have historically been sealed with a wheat-based paste, potentially introducing gluten. However, recent industry changes have replaced wheat paste with gluten-free alternatives like buckwheat flour or paraffin. Despite these updates, the risk of contamination is minimal, with studies showing gluten levels in wine are generally below 10 parts per million. For those with celiac disease, enjoying a glass of wine is usually safe, but consulting with a healthcare provider is always advisable.

Choosing Gluten-Free Wine

For those newly diagnosed with gluten sensitivities or celiac disease, selecting wine aged in stainless-steel vats can be a safer choice, as it avoids the potential risks associated with oak barrels. Additionally, be cautious of flavored wine cocktails, which may contain barley malt or other gluten-containing additives. For a guaranteed gluten-free experience, seek out wineries that offer comprehensive gluten-free options, including both their wines and dining experiences.
