- Picking - For the finest results, the delicate bud and top two leaves are picked
- Withering -The leaves are laid out on racks to dry for up to three hours.
- Heating - Steaming or firing fixes the leaves, to stop oxidation in its tracks.
- Rolling - Most green teas are then rolled, to coax out their aromatic oils.

What is green tea?
Like black tea, green tea comes from the Camellia sinensis, but the difference lies in their exposure to air. While black tea is oxidised for several hours, green is heated before any oxidation can take place, preserving that characteristic light and grassy flavour.
Today, China is the green tea capital of the world - but Japan also exports many fine blends, like Sencha and Matcha, achieved with a unique style of production.
Mythical origins and an Emperor's discovery
Legend has it that in 2737BC, Emperor Shennong - a mythical ruler and father of Chinese agriculture - was enjoying a cup of hot water one day, when a scattering of Camellia sinensis leaves fell into his cup.
And so the phenomenon of green tea was born...
How is green tea made?
Our top tip? Don't stop at one...
If it wasn't love at first sip, be sure to try a few different blends before making your mind up. Sencha, Gyokuro and Dragon Well may all be pure green teas, but each offers a vastly different taste experience, thanks to how they're grown, processed and brewed.
Green tea and caffeine
The biggest green tea misconception? That it's a low-caffeine alternative. At 31mg caffeine per 100ml, it only contains a little less than black tea - but the exact figure varies by blend and length of brew.
How do you brew green tea?
Getting the best out of green tea is easy. Just remember the golden (or green) rule: never brew with boiling water. High heat pulls out the tannins, and a bitter, astringent flavour, so leave the kettle for five minutes before pouring and infusing for two or three.
Personal taste notwithstanding, green tea and milk aren't the best partners, so we recommend letting your leaves be the main character.
Chinese green tea vs. Japanese green tea
The real divide between Chinese and Japanese green tea is heat. The Chinese approach is all fire; leaves are hand-tossed in a hot wok, or tumbled through a vat until that nutty, smoky flavour is released. While the Japanese steam their leaves, then shape them into elegant needles, resulting in a wonderfully fresh taste like that of our Gyokuro.
