If you love tea, you may know that green tea is most famously produced in Japan and China. However, not all green teas are alike. Some have wildly different tastes, and even different health benefits, depending on where they come from.
In this article, I'm going to share:
- What green tea is
- How Japanese green tea is made
- How Chinese green tea is made
- What green tea's health benefits are
- Whether Japanese or Chinese green teas are healthier
- How to brew Chinese and Japanese green teas
- Green tea tips and safety considerations
- Which loose leaf green teas you should check out
Read on to boost your green tea game!
What is Green Tea?
Just like black, white, oolong and pu-erh teas, green tea comes from the Camellia sinensis plant. Unlike black, oolong and pu-erh, though, green tea is unoxidized.
Tea leaves oxidize just like an apple; they turn brown if left exposed to the air. This chemical reaction changes the taste of the tea, and, to state the obvious, reduces the amount of antioxidants in the leaf.
This is why green and white teas have more antioxidants than black, oolong and pu-erh teas.
Green tea is produced everywhere that tea is grown; however, Japan and China are famous for their green teas. They have elevated their production to an art form.
Because green tea is minimally processed and unoxidized, there is little room for error when it comes to the taste profile. Unlike with, say, a roasted oolong where the heavy roasting can obscure a poor quality tea, there is no room to hide when making a green tea!
Japan and China have developed their own styles and methods of making green tea, to such an extent that, with some teas, you'd be surprised that they come from the same plant.
The practice of drinking green tea for medicinal purposes began in China, and the first recorded use was 4,000 years ago! Really, that says about all that needs to be said - if it's been popular that long, it’s gotta be good.
How Is Japanese Green Tea Made?
Japanese green teas are more standardized in flavor than Chinese green teas. There are multitudes of green tea grades, and with Japanese green tea, you can be pretty certain what that cup of tea will taste like based on name and grade.
Japanese green teas are steamed, and many grades are grown in the shade, which yields a higher chlorophyll content. This means that Japanese teas tend to produce a greenish liquor.
I will be writing a future post about the specific types of Japanese green tea, but for now, you can check out Elizabeth and Vientiene's travel blog for their piece on Japanese tea types - from sencha (pictured above) to bancha, tencha, hojicha, genmaicha and gyokuro.
How Is Chinese Green Tea Made?
Because Chinese teas are lower in chlorophyll than Japanese greens, they tend to brew a tea with golden and brown tones (check out the photo above to see what I mean!).
Chinese tea leaves are generally picked every two weeks during their season (depending on the type), and then solar withered in rooms beneath glass ceilings to prevent oxidizing. They go through a second step of withering before being pan-fried.
Far and away the most famous of all Chinese green teas is Dragonwell, also known as Longjing. It is also one of the most ancient, with records of its planting dating back to 618 CE!
Dragonwell can only be harvested two weeks out of the whole year, and is gently hand fried. The leaves are broad and pressed entirely flat, and it brews a rich golden color.
The flavor is smooth and unique, with a creamy mouthfeel. We have Superior Buttery Dragonwell Green Tea if you want to try it for yourself!
Other common Chinese green teas include:
- Gunpowder, so named because the tea leaves are rolled into pellets
- Green Snail Spring (it looks like snails)
- Jasmine Pearls (it looks like pearls)
- Maofeng (Yellow Mountain Fur Peak, whose leaves have delicate yellow hairs).
Chinese tea names are definitely descriptive! These are the main types of Chinese green tea, though bear in mind there are thousands of variations.
The Health Benefits of Green Tea
The health benefits of the many green teas are numerous - not surprising, when you consider that it originated in China as a medicinal drink.
- Green tea contains EGCG (Epigallocatechin gallate), an antioxidant unique to tea which increases metabolism and supports healthy weight loss.
- EGCG plays a role in helping with glucose management, mainly by interfering with the process of breaking starch down into sugar.
- Green tea helps protect the heart, due to its ability to accelerate heart antioxidant defense mechanisms and normalize lipid peroxidation levels. Long story short, the cardioprotective effects are largely due to its antioxidant content! Read the study here.
- Green tea catechins seem to help balance "good" and "bad" cholesterol. Read the study here.
- Green tea can prevent infections, as well as helping to address ongoing infections. This is because it contains catechins, which exhibit antibacterial and antiviral properties.
- Green tea aids relaxation, thanks to its high levels of theanine - an amino acid that induces relaxation, antagonizes caffeine, and can help manage anxiety by reducing excitatory brain chemicals.
- Green tea can help decrease blood pressure! The flavonoids in green tea dilate the blood vessels, allowing blood to flow more freely. Read the study here.
The ORAC level of green tea varies considerably by tea type; however, the general value is 1253.
ORAC is a measure of antioxidant levels that allows comparison between different foods and teas. To learn more about how ORAC is measured and what it reveals about different teas, check out my post on the subject.
Decaf Green Tea Benefits
Incidentally, a 2012 study found that low-caffeine green tea had higher levels of antioxidants than standard green tea.
For this reason, decaf green tea's benefits can be even better than green teas with higher caffeine levels (note: decaf tea still contains a little caffeine, but not much).
If a decaf green tea sounds like the drink for you, hojicha (a green tea from Japan) fits the bill perfectly. Check out our ethically-sourced Sleep Easy Hojicha Roasted Green Tea if you want to try it for yourself!

Are Japanese or Chinese Green Teas Healthier?
The answer to this one is simple. You may remember that Japanese green teas are often grown in the shade, which gives them a higher chlorophyll content. More chlorophyll equals a richer nutrient density.
Japanese green teas are also higher in amino acids, and they act to support the immune system. The green tea health benefits of those hailing from this little island are remarkable!
The verdict is pretty clear - Japanese green teas are healthier.
That said, both Japanese and Chinese green teas have amazing health benefits. No matter which kind you prefer, you can be certain of getting a brew that your body will appreciate.
How to Brew Green Tea
These brewing instructions below are taken from our "Ultimate Guide to Brewing Tea and Tisanes" blog post. There's a lot more information there! But here's what you need to know for green tea specifically.
In general, green tea is delicate and burns easily. When it burns, it becomes bitter and astringent, and probably tastes like the green teas you've had in restaurants and diners.
When it ISN'T burned, you will discover a whole range of personalities. Some are extremely sensitive to heat (gyokuro and sencha are good examples), and others are able to handle near-boiling water without issue (e.g. hojicha, like our Sleep Easy Hojicha Roasted Green Tea).
- Use 1-2 tsp (heaped) of green tea, depending on how densely packed the leaves are. For example, only use 1 tsp for a dense tea like the Japanese Sencha, but use 2 tsp+ for the looser Chinese Flowery Osmanthus Tea.
- Rinse your tea leaves with water that has just started simmering, and discard the rinse water. This 'wakes up' the leaves and removes small particles that can make it astringent. You can also use cold tap water for ease.
- Pour 8 oz (one mug) of ~120-180F (50-82C) water over the leaves. Use cooler water for Japanese green teas and hotter for Chinese greens. Again, don't use boiling water! Boiling water will burn the delicate leaves and reduce their antioxidant and nutrient properties.
- Steep for 1-3 minutes. Because green tea is a "true" tea (from the Camellia sinensis plant), brewing for too long will result in a bitter drink. If you want a stronger flavor, use more leaves and steep for the same or slightly less time.
There are some powerful senchas and gyokuros that will brew perfectly in only 5 seconds, and some Dragonwells that require 3-4 minutes, so play around with your timings. When in doubt, try a sip and then decide if it tastes good or if it needs a bit more time.
Now that you know all about Japanese and Chinese green teas, you need to try them!
Green Tea Tips & Safety
I get questions all the time asking about green tea's health benefits and whether or not it is safe under various circumstances.
Green tea is entirely benign 99.9% of the time. The two main concerns I hear about green tea are these:
Can I drink green tea while I am pregnant?
Green tea is safe to consume appropriately during pregnancy - the main concerns center around caffeine content. So enjoy the tea, but don’t go over a cup or two per day.
Also, caffeine content is directly dependent on the water temperature used when brewing. The cooler the water, the less caffeine will end up in your body. Thus, if you're concerned, why not try cold-brewing your green tea for a refreshing drink?
Green tea can also benefit pregnancy in small amounts!
Is green tea bad for your kidneys?
If you have a kidney disease, you should always talk to your doctor before taking botanicals. That said, the main key lies in the dosage and in your kidney health. Basically, it’s up to the jury.
Green tea contains compounds that can both protect and support kidneys, and others that may be mildly problematic. If you have kidney disease, be sure to enjoy in moderation with your doc’s go-ahead.
If you are prone to kidney stones, good news! A new study found that green tea contains components that prevent the formation of kidney stones.
If you have healthy kidneys and are staying hydrated by drinking plenty of water throughout the day, a few cups of green tea are unlikely to be any cause for concern. So pull up a chair and sip away!
A Note From The Herbalist...
I love sipping green tea. The complex flavor profile, full of surprising notes such as sweet, nutty, mild, tart, astringent, floral, vegetal, and even savory never ceases to amaze me.
I also love the culture that surrounds green tea, with tea first being drunk in China thousands of years ago! As China is enormous, with many different climates, their tea culture has evolved into a varied treasure trove of teas. You have the pu-erhs from Yunnan, the white teas from Fujian, and green and oolong teas from all over (the main areas being in the south of China).
The size of China means that exploring it can take a lifetime, which is no bad thing if that means drinking tea along the way!
Of course, if you don't have a lifetime, you can choose a region at a time, or you can go full adventurer and do an overland driving expedition to see it all at once.
Some friends of Matcha Alternatives have actually done this, spending 40 days driving and camping around China - and having some wild adventures (and teas, I'm sure) along the way. You can read about their experience here if you're curious about what goes in to a China-wide expedition! Their blog is called Overlandsite.com and they drive everywhere.
The founders of Matcha Alternatives are full-time travelers, which is how they got to know Evelin and Ferenc at Overlandsite - these two truly take it to the next level!
Best green teas to get you started...
Now that you're excited to try some Chinese and Japanese green teas, here are some of my favorites:
