Caffeine in Matcha

Matcha tea comes from the nutrient-rich leaves of the green tea plant. Green tea and matcha contain caffeine. Since matcha utilizes the entire green tea plant, the caffeine content of matcha may be higher than that of the average cup of green tea.

Does Matcha Have Caffeine?

An 8 oz glass of Matcha green tea will provide you with about 70 mg of caffeine. The caffeine informer determined this caffeine dosage using a 2 gram serving of Matcha green tea powder (1 teaspoon). If you are looking for a big boost of caffeine, start with a tablespoon of organic matcha powder. How much caffeine does your favorite energy drink have? Check this table below to find out!

Caffeine Content of Common Energy Drinks

Drink Type Caffeine Content
Tenzo Organic Matcha
72 mg of Caffeine (1 Tsp Matcha, 12 oz)
Espresso Shot
77 mg of Caffeine (1.5 oz)
Brewed Coffee
95 mg of Caffeine (8 oz) 
Red Bull
114 mg of Caffeine (12 oz)
5 Hour Energy
200 mg of Caffeine (2 oz)


It should be noted that the caffeine content may vary slightly depending on the grade and quality of Matcha green tea you use. Like we mentioned before, Matcha green tea is a powder so the amount of Matcha you use in preparation will change your caffeine intake.

Traditionally in Japan, matcha green tea is prepared in two styles, named “Usucha” and “Koicha”, the difference being the thickness in tea.

Usucha “Thin Tea”: Tsp of matcha green tea (2 grams) + 6-8 oz of hot water. Provides about 70 mg caffeine. Koicha “Thick Tea”: 2 Tsp of matcha green tea (4 grams) + 1-2 oz of water. Provides about 120-140 mg of caffeine! A bowl of Koicha will use about half the amount of water as Usucha and is typically shared among several guests, each taking turns drinking from the same bowl.

So depending on your preference for strength in matcha green tea, a good green glass can contain anywhere from 35 - 140 mg of caffeine. But be careful - 4 grams of matcha green tea whisked with 2 oz of water will come with a bitter bite that is recommended only for an experienced Matcha pallet.

Matcha Green Tea Caffeine Experience

Matcha green tea is amazing if you are looking for a clean, calm and focused energy boost. There are no spikes, jitters or sudden crashes like you might have previously experienced with coffee and energy drinks. The caffeine will gently pick you up, provide you with an extended energy boost and then will let you softly back down to earth. The effect is extremely pleasant for most people because you don’t experience any of the jitteriness or headaches associated with the caffeine from coffee.

Matcha green tea won’t make you “wired”

Caffeine is generally great for improving concentration, attention and focus but it has its downsides like increasing heart rate, blood pressure, and creating an anxious/jittery feeling. That’s where Matcha green tea stands apart from the rest of it’s caffeinated competitors. There’s a special “feel good” amino acid in green tea called L-theanine that works with caffeine to reduce stress and anxiety while promoting a relaxed state that doesn’t make you feel tired. L-theanine takes the edge off of stimulants and provides an extended (4-6 hour) energy boost with improved cognition and attention. L-theanine is a large part of the reason that people feel so good after drinking Matcha green tea!

You don't want the jitters! Feel the power of clean energy with a cup of Tenzo Tea's organic matcha powder.

For the last 1000 years, Matcha green tea has been prepared in Japan and China as part of a mindful and spiritual practice. Zen Buddhist monks drank Matcha green tea to remain calm and alert during long hours of meditation, and during the 13th century, the monks introduced Matcha green tea to samurai warriors as a pre-battle drink for increased energy and endurance for long battles.

If the thought of caffeine makes you wary, you don’t have to worry. The energy boost in Matcha green tea will help you relax! Crazy right?

Check out this awesome description of the Matcha green tea caffeine experience by Dana Velden.

“The caffeine hit of an espresso can be a bit like having an express train screaming through the middle of your body: a deep, powerful, jittery roar. I find the effects of Matcha to be just as stimulating but in a more delicate, refined way, as if a thousand butterflies have descended on my body, beating their wings until I’m lifted, gently but resolutely, a few inches off the ground.” - Dana Velden,

Matcha vs Coffee Caffeine Content

Matcha Green Tea vs Coffee

There is more caffeine in a regular cup of coffee than there is in Matcha green tea. Brewed coffee contains about 95 mg of caffeine, about 25 mg more than Matcha in an 8 fl oz beverage.


The caffeine from coffee starts with a blast and ends with a crash. It causes a spike in adrenaline, glucose and insulin levels, which in turn create jitteriness, nervousness, and, at least for me, lightheadedness and crazy hunger pangs. Like we mentioned before, the combination of L-theanine with caffeine in matcha green tea promotes an extended 4-6 hour focused energy boost without the jitters, anxiety or sudden mood plummets.

Better Breath, Better Teeth

Matcha green tea dominates coffee in the oral hygiene category. Green Tea polyphenols have shown to reduce the production of all compounds that cause bad breath*. Coffee on the other hand is highly acidic, which allows bacteria to reproduce at a disturbing efficiency. When you add milk, creamers and even non-dairy creamers to your coffee, the overgrowth of bacteria in your mouth continues to get worse. Studies have found that Matcha green tea has antimicrobial properties, which means that it helps reduce bacteria that cause cavities, tooth decay, plaque and bad breath.

Better Skin

The natural antioxidants in Matcha green tea prevent many signs of aging by trapping and inactivating free radicals in the skin*. Green Tea is also an amazing anti-inflammatory agent and has been found to effectively treat acne and rosacea*. The best way to experience results with better skin is to apply matcha green tea powder directly with an easy to make, Tenzo Face Mask.


Matcha has the highest antioxidant rating of all major superfoods*. There’s an antioxidant super molecule in the Catechin family called EGCG that is found almost exclusively in green tea that has been found to prevent the risk of cardiovascular disease and neurodegenerative diseases, strengthen the immune system, and boost metabolism*.

Easier to Make

It takes about 30 seconds to combine green tea powder with hot water by whisking or shaking to make matcha green Tea. There’s no complicated machinery, no extensive filter and drip process and no detrimental waste like the current problems associated with K-cups. Creating a perfect rich cup of matcha green tea is as easy as finding the perfect scoop to water ratio. It’s impossible to mess up!

Matcha vs Green Tea Caffeine Content

Matcha vs Regular Green Tea

The dose of caffeine in regular steeped green tea is significantly lower than what is found in a glass of matcha green tea. Steeped green tea contains about 25 mg of caffeine, about 55 mg less than matcha green tea in 8 fl oz of tea.

Difference in Color

When drinking a glass of matcha green tea, you will notice a vibrant green color along with a rich consistency that creates an opaque quality in a clear glass. This comes as a major surprise to regular (steeped) green tea drinkers that are familiar with a murky transparent greenish-brown liquid. The vibrant and rich color in matcha green tea comes from the extremely high levels of chlorophyll that are produced in the unique shade growing process.

Difference in Preparation

Matcha green tea is prepared by directly combining the finest, hand-picked, baby green tea leaves with water. The stems and veins are removed before stone grinding Matcha green tea powder. This allows you to fully ingest the most nutritious part of the plant. Standard green tea is made by steeping a tea bag filled with a bunch of random green tea parts resulting in a greenish-brown tea water. Don’t believe me? Try ripping open a bag of Lipton Matcha Green Tea and comparing it side by side with Tenzo Matcha Green Tea. The piles in front of you will speak for themselves.

Health Benefits of Matcha vs Green Tea

Matcha green tea really stands apart from steeped green tea when comparing the nutritional value. It’s estimated that you need to drink 10-15 cups of green tea to equal the amount of nutrients in one cup of matcha green tea. Nothing can compare to isolating and fully ingesting the most nutritious leaf matter of the green tea plant.

Daily Caffeine Recommendation

How much caffeine is too much?

Up to 400 mg per day appears to be a safe amount of caffeine for most healthy adults*. That’s roughly the amount of caffeine in 8 medium strength Tenzo Matchas, four cups of brewed coffee, 10 cans of coca-cola or two “energy shot” drinks. Some people are more sensitive to caffeine than others and may experience unwanted side effects from just one cup of coffee or tea. How your body reacts to caffeine may be affected by how much caffeine you drink on a regular basis. The human body will develop a tolerance to caffeine after consistent exposure. People who don’t drink caffeine regularly may be more sensitive to its negative side effects.

Caffeine in Matcha Green Tea is beneficial for a healthy lifestyle

Caffeine has been shown to have a positive influence on the body if it is consumed in moderate amounts. Caffeine helps to increase memory formation, detoxes the liver and increases stamina during exercise. The caffeine in matcha green tea has been found to help people achieve their weight loss goals by boosting daily metabolism by up to 30%!

Here’s what former coffee drinkers are saying

“This is the BEST tea EVER! I’ve been drinking it in place of my coffee and I actually prefer it now. It’s very smooth and makes the best latte.” - Melissa - February, 6th 2016

“Deliciousness! I blend it with steamed cashew milk every morning and have completely replaced my morning coffee with it” - Amanda Blodgett - December 17th, 2015

“I used to drink coffee every single morning - sometimes two cups. With matcha green tea, I have replaced coffee completely with one cup and only a tiny little scoop” - A. Burton November 2015

“ It gives me a controlled energy boost when I need it, and I’m sold on its potential long-term health benefits, even though there’s no way for me to measure the effects of antioxidants on my body during a week-long, very unscientific experiment. But most of all, I love the way matcha green tea smells, lightly sweet and grassy, a scent that reminds me that a good cup of tea is always worth lingering over. “ - Rebecca Straus , Rodales Organic Life

“It gave me energy. Unlike a lot of other sleepy office workers, I don’t depend on caffeine to get me going in the morning. I drink coffee because I like the taste, not the side effects. Caffeine makes my thoughts race and my stomach queasy if I have too much, so given my low caffeine tolerance, I was curious how I would fare with matcha green tea, which has about half the caffeine of coffee and twice the caffeine of regular green tea. It turned out to be perfect - I felt alert, but less jittery than I do with coffee.” Rebecca Straus , Rodales Organic Life

Hey Dean, Tenzo’s new Organic matcha has 36mg of caffeine per gram (1/2 Tsp) which equals 72mg of caffeine per Teaspoon. We just had it tested. Sorry for the confusion! We upgraded our matcha quality and the packaging will be updated in the near future :)

Hey Carla, glad to hear you love your Starter Box! At this point we don’t offer whisking bowls on the website but we are developing the perfect matcha bowl right now and hope to offer it online someday soon. For now I would recommend using a small cereal bowl or a mug with a wide top :)

I just received my starter kit and LOVE your matcha. Just wondering, though, if you intend to sell matcha bowls on your website. I don’t really have the right shaped dish for whisking and looked for something on your website, but couldn’t find anything!

I love the matcha premium and I brew some every day! I have a question about the caffeine part in this post. It says that 1 tsp provides about 70mg of caffeine, but on my bag of the Tenzo premium it says 52 mg for each tsp. Are both just approximate?
