Become a Tea Expert with our Japanese Green Tea Crash Course

Green tea is deeply entrenched in Japanese culture, history and tradition. Tea ceremonies were a universal aspect of everyday life in Japan; from feudal lords settling political disputes or forging alliances to its ever-presence in boardrooms and business meetings. The prevailing importance of this caffeinated drink cannot be questioned.

Tea is not just a drink in Japan, tea is life. Green tea is offered free of charge as soon as customers are seated, and refills are normally par for the course. It’s not out of the ordinary, in Japan, to consume tea when you are under the weather (then again this seems like a given!)

Let’s get the facts straight, Japanese green tea only accounts for 7% of global green tea production. In fact, 95% of all Japanese green tea is consumed domestically. ONLY 5% of Japanese green tea is exported! Talk about keeping it local.

For anyone looking to become a hotshot in Japanese green tea and adeptly navigate through the myriad that is the main proponent of Wabi-Sabi. Delve into this crash course in the main gree tea varieties out there.

How Japanese green tea is grown

  • Terroir & Weather:

Soil composition, chemistry, mineral content are directly absorbed by the plant, not to mention the water it drinks! Regional weather patterns, rain, proximity to the ocean, elevation all play a role in shaping the nutritional content, flavour and appearance of Japanese green tea.

  • Time of Harvest:

How does harvesting in Spring, Summer or Autumn affect the tea? Tea leaves are picked early in spring since tea buds straight after their winter hibernation offer the sweetest flavours, due to the slowing of growth in the colder months.

During Summertime, tea plants rapidly grow new leaves as sunlight converts into natural sugars with any excess stored in the roots for the coming winter. Maturing leaves during summer are larger but possess little to no sweetness, displaying bitter and astringent flavours due to the large concentration of tannins.

Autumn tea leaves slow down their growth, enabling tea plants to develop additional complexities in their taste before entering a dormant state during winter.

  • Sunlight & Shade:

Sunlight plays a huge part in how a tea plant ends up tasting. Tea plants exposed to sunlight tend to have higher levels of vitamin C and tannins (which gives the tea its sharp taste but also fights cancer!)

The longer a tea plant is grown in shade, the higher the concentration of chlorophyll and amino acids such as L-Theanine. Teas with a higher content of L-Theanine have a sweeter flavour. Shaded tea plants are brighter green in colour due to the chlorophyll. Increasing the length of shading is directly linked to the increasing levels of caffeine in the tea plant.

Let’s get to know all types of Japanese green tea…

One of the most well known Japanese green tea that is famously grown in the shade. Gyokuro goes through a special process of preparation where the tea leaves are covered from sunlight for at least 20 days. Gyokuro is grown only once a year in specific tea plantations — which makes it one of the most expensive teas on the market.

Flavour: Slightly sweet and mellow with a distinct umami taste (similar to nori seaweed). The high concentration of amino acid L-theanine contributes to the distinct taste.

Appearance: Dark green in colour. After infusion, the tea takes on a cloudy, pale, yellow-green colour, which is where Gyokuro gets its name ‘jade dew’ from.

Health Benefits: Contains catechins which boost metabolism and lowers blood pressure, to maintain a healthy heart.

Trivia: The finest Gyokuro is produced in the Kyoto region. Gyokuro was first discovered and brewed by a member of the same Yamamotoyama Tea Company that made their fortune selling Sencha, in 1835

Matcha is to Japan as champagne is to France. Matcha is a finely milled-form green tea that’s been consumed in Japan for almost a thousand years. Zen Buddhists first used Matcha during their tea ceremonies during the Kamakura period of Japan’s history

Matcha green tea leaves are left under the shade before harvesting. Ceremonial grade matcha only uses leaves picked at the first harvest, usually at the beginning of May. Farmers harvest the first flush leaves for its colour, taste, fragrance and nutritional elements.

Matcha tea powder is produced when the harvested tea leaves are steam dried, to prevent oxidation and stone-ground Matcha.

Flavour: The grade and location of Matcha heavily affect its taste. Low-grade matcha tastes quite bitter and vegetal, high-quality ceremonial grades of matcha is very smooth and even buttery. All Japanese matcha has a strong umami flavour.


Matcha is a talc-like powder that should smell fresh and slightly grassy. The hue of Matcha is an indicator of the quality. High-quality matcha should be bright green, almost electric green. Low-grade Matcha has a dull hue of green that borders on yellow-green.

Health Benefits:

One of the many unique features of Matcha is that it’s the only tea where you can consume the whole tea leaf rather than just steep it. It is extremely high in antioxidants, loaded with catechins; which boosts memory, immune system and concentration. Matcha can also help with weight loss and the burning of calories.

Trivia: Matcha is not to be confused with standard green tea powder — this is usually much lower quality tea that has not undergone the extensive process.

A combination of Bancha tea leaves mixed with roasted brown rice, also known as “pop-corn” tea. Originally a drink for poor farmers who couldn’t afford the more extravagant teas, the rice served as a filler to reduce the price paid for tea. Monks and soldiers who went through long periods without a proper meal sought out Genmaicha as an inexpensive nutritional drink.

Flavour: The nutty flavour of the brown rice balances out the bitterness of the tea leaves, giving the drinker a lovely popcorn-like taste.

Appearance: Light Yellow hue.

Health Benefits: Genmaicha reduces the bad cholesterol in your blood and increases the good cholesterol. The selenium in Genmaicha improves blood flow and lowers the chance of heart disease.

Trivia: Some of the rice kernels actually do pop during the roasting process.

While most Japanese teas are just steamed, Hojicha, also, undergoes a roasting process in a porcelain pot over charcoal. Hojicha tea leaves are typically low-grade leaves since higher grade leaves are too delicate for the high-temperature roasting process.

Flavour: A signature earthy aroma and deep umami smokey taste.

Appearance: light to reddish-brown in colour.

Health Benefits: A great stress reliever. Its low levels of caffeine but high levels of amino acid L-Theanine means that Hojicha is great for those late afternoon tea sessions that help reduce mental and physical stress and lower cortisol levels.

Trivia: Often made from Bancha tea leaves but can also use Sencha (unshaded green tea), or Kukicha (twig tea). Not only is Hojicha a great decaf alternative due to its low levels of caffeine but it can also come in tea powder form for drinking, cooking and confectionery. Try a Hojicha latte!

A type of Gyokuro tea that originates from the Yame region of the Fukuoka Prefecture, with a history spanning 600 years, after being brought over by a Zen priest Eirin Suzui. Yamecha is high in flavour-producing compounds such as theanine, glutamic acid, and arginine.

Yamecha fields are situated on gently-sloping mountain faces, which are often shielded by fog. This environment helps protect the tea leaves from direct sunlight and produce a richer flavour.

Appearance: Dark green

Health Benefits: Like any Gyokuro type teas, Yamecha is high in catechins, which boosts the metabolism and lowers blood pressure, to maintain a healthy heart.

Kabusecha is Sencha tea after it has undergone a specific amount of shading before harvest, Kabusecha translates to “shaded tea”. For reference, regular Sencha leaves are unshaded and Gyokuro leaves go through about 20 days of shading, with Kabusecha receiving 10–14 days of shade.

Kabusecha is considered a low-quality Gyokuro.

Flavour: Refreshing with a potent “umaminess”. Kabusecha tea sits between Sencha and Gyokuro when it comes to flavour.

Appearance: Dark rich green and needle-like leaves. When infused, it produces a green-yellowy colour.

Trivia: The process of shading tea has multiple effects. The more shade, the stronger the umami flavour and the lower the astringency. This is because shading increases the concentration of the L-theanine amino acid in the tea leaf (the chemical component responsible for a green tea’s umami flavour).

RULE OF THUMB: The stronger the umami flavour, the higher the tea quality.
