About Green Tea
Green tea is made from Camellia sinensis leaves that are heated soon after picking, by pan-firing in China or steaming in Japan, to stop oxidation. That quick heat keeps the leaves green and preserves the fresh character that sets green tea apart from oolong and black tea. China and Japan produce most of the world's green tea, from flat, toasty Dragon Well (Longjing) to bright, grassy sencha.
What it tastes like
Expect fresh, vegetal flavors: cut grass, snap peas, spinach, or a hint of seaweed in Japanese styles, and toasted chestnut or sweet corn in pan-fired Chinese ones. A well-brewed cup is smooth and slightly sweet, with only a light astringency.
Other ways to brew Green Tea
In a mug or teapot
Use one teaspoon (2–3 g) per 8 oz (240 ml) cup. Heat water to 167–185°F (75–85°C), or boil it and let it rest with the lid off for three to five minutes, then steep 1–3 minutes. Japanese steamed greens like sencha want the cooler water and shorter time; pan-fired Chinese greens like Dragon Well can take a little more of both. Take the leaves out as soon as it's done.
In a glass, Chinese style
In China, green tea is often brewed straight in a tall glass. Put a teaspoon of leaf in the glass, add a little water around 175°F (80°C) to wet the leaves, then fill it up. Drink it as the leaves sink, and top it up with hot water when it's a third full. It works best with flat or needle-shaped teas like Dragon Well.
In a kyusu or small pot
For Japanese greens, use about 5 g of leaf in a 6–8 oz (180–240 ml) side-handled pot with water around 160–175°F (70–80°C). Steep about a minute, then pour out every last drop, since that's where much of the flavor is. Re-steep straight away for 15–30 seconds.
Iced green tea
Brew double strength, about 5 g in 8 oz (240 ml) of 175°F (80°C) water for 2 minutes, then pour over ice. Iced green tea goes bitter quickly if over-steeped, so keep the time short.
Cold brew
Green tea may be the best tea of all for cold brewing. Use about 5 g per 8 oz (240 ml) of cold water and refrigerate for 4–8 hours, less time than black tea needs. It comes out sweet, smooth, and savory, with almost no bitterness. Drink it within two days.
Can you re-steep Green Tea?
Yes. Good loose green tea gives two or three steeps. Pour the first infusion off completely, then steep the second for about the same time or a little less; the leaves are already open, so they give up flavor fast. Add 30 seconds or so for the third. Tea bags and broken leaf usually give one good cup.
Ways to drink Green Tea
With honey or lemon
Good green tea rarely needs anything, but a little honey softens it and a squeeze of lemon brightens it. Skip milk, which mutes the fresh, vegetal flavors.
Flavored greens
Jasmine green tea, mint green tea, and genmaicha (green tea with toasted rice) are all brewed like plain green tea. Genmaicha can take slightly hotter water.
Green tea latte
Most green tea lattes are made with matcha, not steeped leaf, because steeped green tea is too light to carry milk.
