Buckwheat tea, also known as sobacha, is a beloved beverage in many parts of Asia. Made from roasted buckwheat groats, this caffeine-free tea has a delightfully nutty, earthy flavor and potential health benefits that are attracting more fans worldwide.
What is Buckwheat Tea?
Buckwheat tea, or sobacha, is made from the roasted groats (hulled seeds) of the buckwheat plant. Despite its name, buckwheat is not related to wheat but is actually an edible fruit seed that is gluten-free.
The origins of buckwheat tea can be traced back to China, where it has been consumed for centuries. However, it became especially popular in Japan during the 16th century before spreading to other parts of Asia.
Buckwheat tea has an earthy, nutty flavor that is often compared to tea made from roasted brown rice or barley. Unlike traditional caffeine-containing teas, buckwheat tea is completely caffeine-free, making it a relaxing nighttime beverage.
Where Does Buckwheat Come From?
The buckwheat plant is native to Southeast Asia and is believed to have originated around 6000 BC in the Balkan region of Europe. It then spread to China and Central Asia, where it became a staple crop, before being introduced to North America by Dutch colonists in the 17th century.
Buckwheat is now grown all over the world, including the United States, Canada, China, Russia, Ukraine, Kazakhstan, and Eastern Europe. The top producers are China, Russia, and Ukraine.
Common buckwheat varieties used to make sobacha tea include Japanese buckwheat and Silverhull buckwheat. Japanese buckwheat is preferred for its flavor while Silverhull is higher yielding.
How is Buckwheat Tea Made?
To make buckwheat tea, the buckwheat groats are first roasted, which gives them their signature nutty flavor and brown color. The traditional Japanese method involves roasting in an iron pot over charcoal, but commercial buckwheat tea is often made in large roasters.
The roasted groats are then steeped in hot water to produce the tea. The steeping time can range from a few minutes to several hours depending on the desired strength. Unlike green or black tea, buckwheat tea does not become bitter with long steeping.
In Japan, buckwheat tea is traditionally served in a kyusu teapot with small, handleless cups called sobachoko. The tea is typically enjoyed unsweetened, allowing its roasted, earthy flavor to shine.
How is Buckwheat Tea Consumed?
In Asia, buckwheat tea is mainly consumed hot, often replacing green tea as a caffeinated alternative. It is frequently served during meals, especially soba noodle dishes, as its flavor complements the dish.
Some people also enjoy buckwheat tea chilled, turning it into a refreshing cold beverage for summer. Adding milk, honey, or lemon can mellow out its strong roasted taste for those new to sobacha.
Buckwheat tea is also often used in cooking to add flavor to soups, stews, broths, and even desserts. In Japan, sobacha is incorporated into sweets like cakes and candy.
What are the Benefits of Buckwheat Tea?
Buckwheat tea has been prized in traditional Chinese medicine for centuries and is associated with numerous potential health benefits:
- Antioxidants: Buckwheat tea contains high levels of polyphenol antioxidants, which may help reduce inflammation and cellular damage.
- Blood circulation: Compounds in buckwheat tea may help improve circulation by strengthening blood vessels and lowering blood pressure.
- Cholesterol: The rutin content in buckwheat has been linked to lower LDL (bad) cholesterol levels, which supports heart health.
- Blood sugar: The polyphenols may help slow carbohydrate digestion and improve insulin sensitivity.
- Digestion: It can act as a prebiotic to feed healthy gut bacteria and may relieve constipation.
- Relaxation: The L-tryptophan amino acid in buckwheat tea promotes serotonin, which has a calming effect.
However, more research is still needed to fully understand the mechanisms behind buckwheat tea’s health benefits.
The History of Buckwheat Tea
Buckwheat has been used for food and medicine in China since around 1000 BC. However, buckwheat tea emerged later in Japan during the Muromachi period (1336 to 1573).
At this time, the Japanese Zen Buddhist monk credited with introducing tea to Japan, Eisai, also began promoting buckwheat tea as a medicinal beverage. The tea quickly spread through Buddhist temples before becoming popular among the upper class of Kyoto.
In the 1600s, buckwheat became a staple crop of poor farmers in Japan. Consuming the leftover roasted buckwheat groats as tea became an affordable alternative to expensive imported teas. Its popularity then spread to the rest of the country.
The health benefits of buckwheat tea were widely touted in medicinal books of the Edo period, cementing its status as a nourishing beverage that still continues today.
The Different Types of Buckwheat Tea
There are a few main ways that buckwheat tea is processed and served:
- Roasted buckwheat tea (soba-cha) – The most common type, made by roasting raw buckwheat groats to bring out the signature flavor.
- Unroasted buckwheat tea (memma-cha) – Made from unroasted green groats, this has a milder, more cereal-like taste.
- Smoked buckwheat tea (kasha tea) – The buckwheat is smoked over oak, maple, or cherry wood before being steeped, adding a rich smoky essence.
- Mulberry smoked buckwheat – Popular in Korea, the buckwheat is smoked with mulberry wood chips for a deliciously fruity aroma.
- Hulled vs unhulled – Hulled groats (with the outer husk removed) produce a milder tea compared to stronger, nuttier unhulled varieties.
- Blended buckwheat tea – Sometimes combined with other ingredients like goji berries, ginseng, or matcha powder for unique flavor profiles.
How to Brew Buckwheat Tea
Brewing the perfect cup of hot buckwheat tea takes just a few easy steps:
- Start with 3-4 tablespoons of roasted buckwheat groats per 8 oz cup of water. Unroasted groats may need more since they absorb water.
- Bring fresh cold water to a boil in a kettle. Spring water is best to prevent interfering tastes.
- Rinse the dry groats briefly in a sieve to remove any dust.
- Place the groats in your teapot or infuser. Brewing loose leaf allows more expansion.
- Pour the boiling water over the groats and let steep for at least 5-15 minutes. You can steep for a few hours.
- Taste frequently and adjust the strength to your liking by changing the amount of groats or steep time.
- Enjoy the earthy, nutty brew hot, or chill overnight in the fridge for refreshing cold buckwheat tea!
How to Drink Buckwheat Tea
Here are some tips for enjoying buckwheat tea:
- Drink it plain to fully savor the natural roasted flavor.
- Sweeten with a bit of honey or maple syrup if the bitterness is too strong.
- Add milk, plant-based milk, or creamer to mellow the flavor.
- Try a squeeze of lemon which complements the earthiness nicely.
- Mix with fruit juice or blend with fruit to make a smoothie.
- Pour it over ice for an invigorating iced tea.
- Simmer the groats in broth for a nutritious, antioxidant-rich stock.
- Use instead of water to cook rice, quinoa or oats for bonus nutrition.
- Include it in marinades, sauces, stews or baked goods for rich flavor.
The Health Benefits of Buckwheat Tea
Modern research is uncovering more about the powerful health benefits long associated with drinking buckwheat tea:
Rich in Antioxidants
Buckwheat tea contains high levels of polyphenol antioxidants, including the flavonoids rutin and quercetin. These helps combat free radicals which damage cells and cause disease. Rutin specifically may strengthen blood vessels.
Improves Heart Health
The antioxidants, along with lignin and other compounds, are tied to better circulation and lower blood pressure. Buckwheat tea also appears to reduce LDL cholesterol while increasing HDL cholesterol. This combination benefits cardiovascular health.
Regulates Blood Sugar
The polyphenols in buckwheat tea inhibit alpha-glucosidase, the enzyme responsible for digesting carbs into glucose. This results in a slower spike and overall lower rise in blood sugar after eating. Buckwheat tea may also increase insulin sensitivity. Both effects are especially helpful for managing diabetes.
Buckwheat tea has prebiotic properties, meaning it feeds the good bacteria in the intestines. A 2015 study found regularly drinking buckwheat tea increased the population of beneficial Bifidobacterium. Better gut flora improves digestion and immunity.
L-tryptophan is an amino acid found in buckwheat that the brain uses to produce mood regulating neurotransmitters like serotonin. Higher serotonin levels promote relaxation and can combat anxiety and sleep issues. This makes buckwheat tea an ideal nightcap.
The Potential Side Effects of Buckwheat Tea
Buckwheat tea is considered very safe for most people when consumed in normal food amounts. However, there are a few things to be aware of:
- Since it is gluten-free, buckwheat tea is safe for people with celiac disease or gluten intolerance. Those with a wheat allergy should still exercise caution.
- Buckwheat does contain oxalates which can cause kidney stones in susceptible individuals prone to absorbing too much oxalate. Avoid overconsumption if you have a history of kidney stones.
- The rutin content may pose a bleeding risk or interact with blood thinning medication. Check with your doctor if taking anticoagulant drugs.
- As with any herbal product, allergic reactions are possible. Discontinue use if any reaction occurs.
- Children or pregnant/nursing women should not consume in excess due to lack of safety research.
Most healthy adults can safely enjoy a few cups of buckwheat tea per day. But check with your doctor if you have any medical conditions or take medications to avoid complications.

The Science Behind Buckwheat Tea
Several compounds and nutrients in buckwheat tea contribute to its health properties:
Rutin – This antioxidant flavonoid strengthens blood vessels. It also helps vitamin C absorption and has anti-inflammatory effects.
Quercetin – Another flavonoid that is a natural antihistamine and anti-inflammatory to reduce allergies, arthritis, and blood pressure.
Catechins – These polyphenols have antioxidant, anti-cancer, blood sugar-lowering, and cholesterol-lowering capabilities.
Fagopyrins – Light-sensitive compounds in buckwheat that act as antioxidants but can also cause photosensitivity.
Minerals – Buckwheat contains high amounts of iron, zinc, manganese, copper, and magnesium. Manganese enhances enzyme function while magnesium relaxes muscles and nerves.
Protein – Buckwheat delivers high-quality complete protein with all essential amino acids to support the immune system.
Prebiotics – Starch and fiber in buckwheat act as prebiotics to feed healthy gut flora, improving digestion.
These compounds give buckwheat tea its therapeutic properties. However, more clinical research is still needed on the mechanisms.
Buckwheat Tea and Weight Loss
Can sipping buckwheat tea help shed those extra pounds? While no food inherently causes weight loss, buckwheat tea does have some slimming advantages:
- It has no calories when brewed without added sweeteners.
- The fiber creates a feeling of fullness and satisfaction.
- It is caffeine-free unlike traditional black and green teas. Caffeine can interfere with weight loss.
- Compounds in buckwheat tea may reduce carb and fat absorption and increase fat cell breakdown.
- Its prebiotics improve gut health, which is tied to better metabolism and weight regulation.
- Manganese balances blood sugar to reduce fat storage and cravings.
- The calming effect helps prevent stress-induced emotional eating.
Drinking buckwheat tea alone won’t lead to significant weight loss. But when combined with a healthy diet and exercise, it can support your efforts as part of an overall healthy lifestyle.
Buckwheat Tea and Mental Health
Traditionally consumed to calm the nerves, modern research confirms the mental health benefits of buckwheat tea:
Reduces anxiety – L-tryptophan increases serotonin levels while apigenin produces a tranquilizing effect to alleviate anxiety without sedation.
Improves mood – Bioactive compounds increase dopamine and serotonin, the “feel good” neurotransmitters that boost mood and feelings of wellbeing.
Aids sleep – In addition to soothing compounds like tryptophan, buckwheat contains melatonin which regulates the sleep-wake cycle.
Protects cognition – Rutin increases blood flow to the brain to support focus and mental clarity. It also prevents cognitive decline.
Combats depression – The amino acid tyrosine in buckwheat is a precursor for mood-regulating hormones like norepinephrine and dopamine.
By supporting mental calmness and enhancing positive neurotransmitters, regularly drinking buckwheat tea may aid in treating anxiety, depression, and sleep disorders.
