Is Wine Gluten Free?

is wine gluten free

Is wine gluten-free?  This is a question many people need to ask, whether due to gluten sensitivity, celiac disease, or simple dietary choice.  And like with any other food or drink, many people need to ask these questions when shopping for wines.  As far as wine goes, the answer is that most wines do not have gluten.  This is because wine is produced from grapes, whereas gluten is a protein which comes from wheat and other cereal grains.  However, certain wines could contain trace amounts of gluten due to certain wine-making processes, although these situations are not very common. For most practical purposes, wine can be considered gluten-free.

What is Gluten?

Gluten is a protein found in many different cereal grains.  Cereals grains are the edible seeds of various grass species, and includes wheat, rice, corn, buckwheat, millet, barley, oats, sorghum, and rye, among other grains.  Not all cereal grains have gluten.  For example, rice, buckwheat, and corn do not have gluten and are safe to eat for people who are on a no-gluten diet.  However, many of the more common grains are chock-full of gluten.  This includes wheat, rye, and barley.  Many products are made from these grains.  Grains can be ground into flour and used to make baked good (bread, pizza, pastries, cookies, and pasta).  Barley and wheat can also be fermented to make beer.  Other food products such as cereal, crackers, and certain sauces also contain gluten, and should be avoided by people with certain conditions.

Who Should Avoid Gluten?

For most people, gluten is a harmless protein.  However, many people have various levels of gluten sensitivity which can cause issues with consuming it, even in small quantities.  More seriously, people with Celiac Disease have an autoimmune response to gluten.  With this condition, the immune system of the body overreacts to the presence of gluten, which can cause serious symptoms such as stomach pain, skin problems, seizures, and digestive issues.  If proper care is not taken to avoid consuming gluten, Celiac disease can even lead to cancer or death.  For people with Celiac Disease, avoiding gluten is an everyday battle.  There are also people with less serious gluten sensitivities, which can still cause discomfort and other difficulties.  Finally, many health-conscious people decide to avoid gluten rich foods as part of a specialized diet or lifestyle philosophy.

Does Wine Have Gluten?

Generally speaking, wine does not have gluten.  Wine is made from grapes, which are then fermented with yeast to produce an alcoholic beverage.  Grapes do not contain any gluten whatsoever.  However, there are a few vectors through which gluten could be added to wine.

First, it’s possible (but unlikely) for gluten to be used in the fining process.  Fining is the process used to remove larger particles from wine during the winemaking process.  A fining agent is added to the wine, which binds with the suspended particles and precipitates the unwanted particles from the wine.  The precipitated matter is then gathered and separated from the wine.  Various fining agents are used in the wine making process, to include agents made from egg yolks, fish, or milk.  Very rarely, gluten is used as a fining agent.  However, this is a relatively uncommon fining agent.  Furthermore, the fining agent and associated precipitate is removed from the wine, causing the gluten content to be extremely low, even for wines that do use gluten in the fining process.

A second possible vector for gluten in wine is the wheat paste used to seal oak barrels.  Although more modern wine methods often use steel vats for storage and fermentation purposes, some old fashioned wine production methods rely on wooden barrels.  Some of these wooden barrels are sealed using a wheat-based paste.  Although this is a possible way for gluten to be added to wine, it is becoming rarer for modern barrels to contain wheat paste.  In addition, the actual amount of gluten added using this method is very low, even for barrels which contain wheat paste.  Furthermore, any wine which is certified as gluten free must have a gluten content which is below mandated minimum concentrations.

A third possible vector for gluten in wine is through various sweeteners and flavors added to non – traditional wines, such as cooking wines or wine coolers.  Although wine coolers are not wine per se, as much as they are a mixed drink containing wine, it is important to realize that such drinks could potentially contain ingredients with gluten.  The same applies to cooking wine, which again is not what most people have in mind when discussing the nutrition content of wine.  Cooking wine and wine coolers could contain sugar extracted from grain, which is a potential vector for gluten contamination.  With this in mind, people who are trying to avoid gluten may be wise in avoiding wine coolers and cooking wine as a precaution.

Is my Wine Gluten Free?

Generally speaking, it is safe to assume that a wine (except for cooking wine or wine cooler) does not contain gluten.  There are regulatory requirements specifying the allowable gluten concentration for any product labelled as gluten free, meaning any wine labeled as gluten-free should be safe to consume.  Most of the possible vectors for introducing gluten to wine are very rare in the modern wine-making process and add very minute quantities of gluten.  For people with extremely serious cases of Celiac Disease, it may be a good precaution to call the wine manufacturer and ask if any gluten is introduced to the wine during the wine-making process.


For the most part, wine is a gluten free product.  Gluten is a protein found in certain cereal grains, such as barley, rye, and wheat.  This means that various grain-based foods such as baked goods and beer can contain high levels of gluten.  People with Celiac Disease and gluten sensitivities need to find gluten-free items for their diets.  Although in very rare cases, small amounts of gluten can be added to wine through either the use of gluten as a fining agent or from the use of wheat paste in wine barrels, the vast majority of store bought wines do not contain appreciable levels of gluten.
