What is matcha?
Matcha is a finely ground green tea powder made from the leaves of the Camellia sinensis plant. It has been used for centuries in Japanese tea ceremonies and is gaining popularity around the world for its potential health benefits.
Matcha is made from shade-grown green tea leaves that are harvested by hand. The leaves are then steamed, dried, and ground into a fine powder. Unlike regular brewed green tea, matcha contains the entire leaf, so you end up consuming the whole leaf when you drink matcha. This means you get a more concentrated amount of antioxidants, amino acids, and vitamins compared to steeping green tea leaves in water.
What is gluten?
Gluten is a general name for the proteins found in wheat, barley, and rye. It acts as a glue that helps foods maintain their shape and aids in giving elasticity and chewiness to doughs. For those with celiac disease or non-celiac gluten sensitivity, consuming gluten can trigger an autoimmune response that damages the small intestine. This is why following a strict gluten-free diet is essential for managing these conditions.
There are two main groups of proteins that make up gluten: gliadins and glutenins. Each grain contains its own unique makeup of these proteins. For example, the gluten in wheat is made up of mostly gliadins while the gluten in barley contains more glutenins. This is why wheat is more associated with reactions in those sensitive to gluten.
Does matcha contain gluten?
Matcha is naturally gluten-free. Since it is made from green tea leaves from the Camellia sinensis plant, it does not contain any wheat, barley, or rye – the sources of gluten.
Matcha powder is simply the ground up leaves of the tea plant. No gluten-containing ingredients are added during the production process. Tests have shown matcha powder to be free of any traces of gluten.
Some matcha powder packages may have labels indicating the powder is gluten-free. This provides extra assurance for gluten-sensitive consumers but all pure matcha powder will be gluten-free, even without a label.
Are there any risks of cross-contamination?
For individuals with celiac disease or serious gluten intolerances, there is always a concern about cross-contamination affecting the gluten-free status of products. However, matcha production practices reduce the risks of any gluten cross-contamination.
Here are some reasons why matcha has minimal risks for cross-contamination with gluten:
- The tea plants used for matcha are kept separate from gluten-containing grains. There is no contact between matcha leaves and wheat, barley, or rye during growing and harvesting.
- Matcha is processed on separate, dedicated equipment from any gluten-containing products. Shared equipment increases cross-contamination risks, but matcha production avoids this.
- Many matcha brands are processed in gluten-free facilities to further reduce any change of contamination.
- Reputable matcha companies follow good manufacturing practices that emphasize thorough cleaning protocols between productions runs and use analytical testing to verify the absence of gluten.
While cross-contamination can never be 100% ruled out, matcha powder presents very low risks compared to many other processed foods. When selecting matcha, choose trusted brands that state their matcha is gluten-free and processed in a gluten-free facility for added assurance.
Are there any other ingredients added to matcha powder?
Since matcha powder starts out gluten-free, the biggest consideration is whether any other ingredients containing gluten are added during production.
Pure matcha powder contains 100% ground green tea leaves. No other ingredients are added. This matcha powder will be gluten-free and safe for those avoiding gluten.
However, some matcha powder blends do contain added ingredients:
- Sweeteners – Some matcha powders contain natural sweeteners like cane sugar to improve flavor. Cane sugar does not contain gluten.
- Fillers – Rice flour, soy lecithin or maltodextrin may be added as stabilizers. These do not contain gluten.
- Flavorings – Added flavors, spices, fruits and vegetables are sometimes included in flavored matcha blends. These should be checked for any gluten-containing ingredients.
- Thickening agents – Cornstarch or carrageenan are sometimes used to improve texture. These do not contain gluten.
When selecting flavored matcha blends, check the ingredients list to ensure there are no gluten-containing additives like wheat, barley or rye ingredients. As long as all ingredients are gluten-free, flavored matcha powder will still be safe for a gluten-free diet.
Are there certifications to look for?
When shopping for matcha powder, keep an eye out for these labels and certifications:
- Gluten-free – Products labeled as gluten-free must contain less than 20 parts per million gluten.
- Certified gluten-free – Extra validation from a third party certifier like GFCO (Gluten-Free Certification Organization).
- Processed in a gluten-free facility – Reduces risks of any gluten cross-contamination.
- Non-GMO – Non-genetically modified matcha will be made from pure tea leaves.
- USDA Organic – Ensures matcha is grown without chemical pesticides or fertilizers.
- JAS Organic – Japanese Agricultural Standard organic certification.
These labels provide added assurance that the matcha powder has been properly tested and processed to avoid gluten exposure.
Are there any exceptions?
The vast majority of matcha powder available will be completely gluten-free. However, there are a couple exceptions:
- Wheatgrass matcha – This is made from wheatgrass, not Camellia sinensis tea leaves. It contains gluten and must be avoided.
- Ceremonial matcha – Some ceremonial grades may list wheat as an ingredient. This is included to replicate traditional preparation but contains gluten.
- Kitchen cross-contamination – Matcha powder that comes into contact with gluten-containing foods when used in the kitchen may pick up traces of gluten. Proper precautions should be taken.
As long as you purchase unflavored, pure matcha made from tea leaves, it can be part of a gluten-free diet. Just be cautious of matcha blends with questionable ingredients or matcha powder exposed to gluten-containing foods at home.
Should you consume matcha if you are sensitive to gluten?
For individuals with celiac disease, non-celiac gluten sensitivity, or a serious gluten intolerance, matcha is generally considered safe in a gluten-free diet as long as some basic precautions are taken:
- Purchase only pure matcha powder, not blends with questionable ingredients.
- Look for gluten-free labels and certifications on the packaging.
- Choose matcha processed in dedicated, gluten-free facilities.
- Avoid cross-contaminating matcha powder by improper kitchen practices.
- Watch out for the few matcha powder exceptions that may contain gluten.
- When in doubt, contact the matcha company about their production procedures.
Many gluten-free consumers are able to enjoy matcha without issue. However, individuals that are highly sensitive are advised to take extra precautions and be aware of all ingredients and preparation practices.
Some extra sensitive individuals may want to avoid matcha from shared kitchens or restaurants unless they can be assured proper precautions against cross-contamination have been taken. For maximum safety, dedicated kitchen equipment for matcha is recommended.
Can matcha powder be used as an ingredient in gluten-free cooking and baking?
Yes, matcha powder makes a great addition to all kinds of gluten-free recipes. Its vibrant green color and signature taste can be used to enhance the flavor and appearance of everything from smoothies to desserts.
Here are some great ways to use gluten-free matcha powder:
- Add to muffins, cakes, cookies, brownies
- Use in pancake and waffle batter
- Flavor ice cream, milkshakes, yogurt
- Blend into smoothies, lattes, milk tea

Matcha powder works well in both sweet and savory recipes. Just remember to take precautions against cross-contamination when handling matcha powder during gluten-free cooking at home.
What about matcha tea bags?
Many stores carry convenient tea bags of matcha instead of matcha powder. Can these tea bags be safely consumed on a gluten-free diet?
Pure matcha tea bags that contain 100% ground green tea leaves will be gluten-free. However, it is more common for the matcha in tea bags to be combined with other ingredients.
Potential sources of gluten in matcha tea bags include:
- Fillers like wheat fiber or barley malt
- Flavorings containing glutenous grains
- Stabilizers or thickeners using gluten ingredients
- Cross-contamination during processing
Always thoroughly read the full ingredients list on matcha tea bags before purchasing. Avoid any that list wheat, barley or rye ingredients. Contact the manufacturer if in doubt about the gluten-free status.
For maximum safety, purchase tea bags that specifically state they are gluten-free on the packaging. Loose matcha powder is less likely to have questionable additives.
Are there risks when dining out and ordering matcha drinks?
Enjoying matcha lattes and other matcha drinks from coffee shops and restaurants comes with some extra risks for gluten-sensitive individuals.
Some potential concerns include:
- Cross-contamination from shared blenders, whisks, pots
- Matcha powder containing glutenous ingredients
- Milk options that contain gluten, like malt powder
- Flavored syrups with glutenous grains
- Use of contaminated cup or utensils
To enjoy matcha beverages safely when dining out:
- Inquire about all ingredients and preparation procedures
- Request a fresh blender to avoid cross-contamination
- Ask for dairy-free and gluten-free milk options
- Avoid added syrups and flavorings
- Request a clean, unused cup and fresh utensils
Being aware of risks and asking questions can help make matcha drinks from restaurants and cafes safe to consume as part of a gluten-free lifestyle.
