Wine is generally considered gluten-free, with most wines containing less than 20 parts per million (ppm) of gluten. However, there are a few exceptions and considerations for those with celiac disease or gluten sensitivity. Red wine, in particular, has been associated with histamine-induced symptoms that may mimic gluten exposure. In Australia, there are several gluten-free wine options available, including organic and vegan wines. South Australia, renowned for its wine production, offers a diverse range of landscapes, soils, and microclimates, contributing to the country's reputation for innovative and prestigious wines.
| Characteristics | Values |

Most wines are gluten-free, but cross-contamination is possible
Wine is predominantly made from grapes, which are naturally gluten-free. The fermentation process also does not include any gluten. Therefore, most wines are gluten-free. However, cross-contamination can occur during the fining process, where substances are added to the wine to help clarify it. If a winemaker uses gluten or a gluten-containing product as a fining agent, gluten can remain in the wine. This can be harmful to those with coeliac disease or gluten sensitivity.
Wheat paste used to seal the wooden wine casks or barrels used to age the wine can also introduce gluten. While not all winemakers use oak casks or barrels, and not all oak barrels are sealed with wheat paste, this can be a source of cross-contamination for some wines. Studies have shown that the amount of gluten in wines aged in barrels sealed with wheat paste is below the limit for gluten-free classification. Nevertheless, it is essential for those with coeliac disease or gluten sensitivity to be aware of this potential source of gluten.
Additionally, pre-made wine beverages, such as bottled wine coolers, wine cocktails, and flavoured wines, may contain gluten. These products often contain barley malt or other gluten-containing ingredients, making them unsuitable for a gluten-free diet. It is always important to read labels and, if necessary, check with the company to ensure a product is gluten-free.
While most wines are gluten-free, there are exceptions. For those with coeliac disease or gluten sensitivity, it is crucial to be vigilant about the potential for cross-contamination and to choose wines that are certified gluten-free or known to be safe for a gluten-free diet.
In Australia, there are several gluten-free wine options available, including organic and biodynamic wines. Nature's Harvest Organic Shiraz, for example, offers a complex flavour profile and is certified organic and gluten-free. McWilliam's Hanwood Estate 10-Year-Old Grand Tawny is another gluten-free red wine option from Australia.

Fining agents used in wine production may contain gluten
Wine is predominantly made from grapes, which are naturally gluten-free. The fermentation process also does not include any gluten. However, gluten may be introduced during the fining process, which occurs after fermentation and involves adding substances to the wine to help clarify it. Fining agents bind with unwanted particles and debris in wine, which can then be filtered out so that the wine appears clearer. If a winemaker uses gluten or a gluten-containing product as a fining agent, gluten can remain in the wine, which could be harmful to those with celiac disease or gluten sensitivity.
While the use of gluten-containing fining agents is rare, it is possible. For example, wine aged in oak barrels may have been sealed with a gluten-rich, wheat-based paste, which could contaminate the wine with gluten. Additionally, some common fining agents, such as egg whites, casein, and gelatin, may be unsuitable for vegetarian or vegan wine drinkers. However, studies suggest that even if there is gluten in the wine after fining, it is much lower than the 20 parts per million (ppm) threshold for a product to be considered gluten-free.
In Australia, allergen labelling for foods was introduced in December 2002, requiring the presence of potential allergens to be declared on food labels. For wine, this includes added sulfites, certain proteinaceous processing aids, and ingredients such as egg white, milk, and evaporated milk. However, isinglass (fish) is exempt from labelling in wine and beer.
Overall, while it is possible for gluten to be introduced during the fining process, it is important to note that most wines are gluten-free and cross-contamination is rare. Wine is widely considered gluten-free and safe, with studies showing that even if gluten is present, it is typically below detectable levels.

Wines aged in oak barrels sealed with wheat paste may contain gluten
Wine is predominantly made from grapes, which are naturally gluten-free. The fermentation process also does not include any gluten. However, the fining process, which occurs after fermentation, could potentially cause gluten to enter the bottle. During fining, substances are added to the wine to help clarify it, and if a winemaker uses gluten or a product containing gluten as a fining agent, the gluten can remain behind in the bottle. For someone with celiac disease or gluten sensitivity, this could be harmful.
The Tobacco Tax and Trade Bureau (TTB) currently does not allow gluten-free labeling of alcoholic beverages if the producer used storage materials that contained gluten. This means that any wine labeled as gluten-free was likely aged using a barrel alternative and does not contain gluten. To test for gluten in wines aged in oak barrels sealed with wheat paste, the sandwich R5 ELISA test is used to detect any non-hydrolyzed gluten, while the competitive R5 ELISA test is used to detect hydrolyzed gluten.
Overall, while wines aged in oak barrels sealed with wheat paste may contain trace amounts of gluten, they are still considered gluten-free and safe for consumption by individuals with celiac disease or gluten sensitivity. However, it is always important to check labels and be aware of potential cross-contamination during the fining process or when drinking other wine-based drinks such as wine coolers, flavoured wine beverages, and cocktails.

Wine coolers, flavoured wines, and wine cocktails may contain gluten
Wine is predominantly made from grapes, which are naturally gluten-free. The fermentation process also does not include any gluten. However, the subsequent fining process, where substances are added to the wine to clarify it, could potentially cause gluten to enter the bottle. If a winemaker uses gluten or a gluten-containing product as a fining agent, the gluten can remain in the wine. For those with celiac disease or gluten sensitivity, this could be harmful.
Some winemakers seal their oak barrels with a flour paste, which can leach small amounts of gluten into the wine as it ages. While studies suggest the amounts are likely to be very small, this can still be a concern for people with celiac disease or gluten sensitivity. Therefore, those with gluten sensitivities should seek out wines fermented in stainless steel tanks rather than oak barrels. Many wineries now use stainless steel for all or part of their fermentation process.
To avoid the risk of gluten contamination from commercial wine coolers, you can make your own wine spritzers at home using gluten-free wine, club soda, and a splash of juice.

Wines aged in oak barrels sealed with wheat paste can also contain gluten, but the amount is generally too low for it to be considered unsafe for gluten-intolerant individuals. Therefore, wine is widely considered gluten-free and safe.
To alleviate symptoms of gluten exposure, drinking plenty of water can help flush out the system, and eating small, non-spicy, non-fatty meals can aid digestion. Ginger and peppermint tea can also soothe an upset stomach. Probiotics may help digest gluten proteins and prevent symptoms, as well as protect the gut from immunogenic peptides that trigger an autoimmune response. Getting enough rest and sleep is crucial, as the body will be in recovery mode. While the symptoms of gluten exposure can be unpleasant, they are temporary, and a gluten-free diet can help prevent future occurrences.
