As someone who has a passion for wine and follows a gluten-free diet, I’ve frequently wondered if wine has gluten. When managing gluten sensitivity or celiac disease, it’s crucial to be mindful of what we consume, since even a tiny trace of gluten can lead to discomfort and possibly long-term health issues.

Let’s dive deep into the topic and explore whether wine is safe for those who are gluten-sensitive.

Understanding Gluten

Gluten is a protein found in wheat, barley, and rye. It is responsible for the elastic texture of dough and gives bread its chewy texture. For those with celiac disease or gluten intolerance, consuming gluten can trigger an immune response that damages the small intestine.

The Wine-Making Process

During the wine-making process, grapes are fermented, and the juice is extracted. Unlike beer, which is made from gluten-containing grains, wine is primarily made from grapes. Grapes are naturally gluten-free, so in theory, wine should be safe for those avoiding gluten.

However, there are a few factors to consider:

1. Potential Cross-Contamination

While grapes are gluten-free, wineries may use certain additives or process their wines in facilities that also handle gluten-containing products. Cross-contamination can occur during these processes, potentially introducing small amounts of gluten into the wine. However, the level of cross-contamination is generally minimal, and most winemakers take precautions to avoid it.

2. Barrel Aging

Some wines are aged in oak barrels, which may have been sealed with wheat paste or flour-based products. Although the amount of gluten transferred to wine through this method is likely to be negligible, it is worth noting.

3. Flavored Wines

Flavored wines, such as those with added spices or fruit infusions, may contain ingredients that could potentially include gluten. It’s always a good idea to check the ingredients list or contact the winery directly to ensure the wine is gluten-free.

Labeling and Certifications

In many countries, wine manufacturers are not legally required to disclose allergen information, including whether their wine contains gluten. However, some wineries voluntarily label their products as “gluten-free” if they meet certain standards and have undergone testing to ensure minimal gluten presence.

If you are unsure whether a particular wine is gluten-free, several organizations, such as the Gluten Intolerance Group and the Celiac Support Association, offer certifications for gluten-free products. These certifications can provide peace of mind for those with gluten sensitivity.


So, does wine contain gluten? While the risk of gluten contamination in wine is generally low, it’s essential to remain cautious, especially if you have severe gluten intolerance or celiac disease. Checking labels, contacting wineries for more information, and seeking out certified gluten-free wines can help ensure a safe and enjoyable wine-drinking experience.

As a wine enthusiast who follows a gluten-free lifestyle, I have found that being informed and proactive is key. So, next time you raise a glass of wine, you can do so with confidence, knowing that you have made an educated choice.
