About Sencha
Sencha is Japan's everyday green tea, and about two-thirds of the tea grown there. The leaves are steamed within hours of picking to stop oxidation, then rolled and dried into thin, dark green needles. Steaming, rather than the pan-firing used for most Chinese green tea, is what gives sencha its bright color and grassy, savory character. Shizuoka and Kagoshima are the largest growing regions.
What it tastes like
Fresh and vegetal, with notes of cut grass, steamed greens, and a savory, slightly oceanic edge, balanced by a clean sweetness and a light, pleasant astringency. Deep-steamed (fukamushi) sencha is darker, cloudier, and richer; light-steamed (asamushi) is clearer and more delicate.
Other ways to brew Sencha
In a kyusu
The side-handled kyusu is made for sencha, with a fine built-in strainer that holds back the small needles. Use about 5 g (two teaspoons) of leaf for 6 oz (180 ml) of water at 158–176°F (70–80°C). Steep 60–90 seconds, then pour it all out into the cups, alternating between them so each gets the same strength. Shake out the last drops; they're the strongest and sweetest.
In a mug or teapot
Use about one heaping teaspoon (2–3 g) per 8 oz (240 ml) cup and water at 158–176°F (70–80°C). Steep 60–90 seconds and strain. Sencha needles are fine, so use a fine mesh infuser rather than a coarse basket.
Cooling the water without a thermometer
Boil the water, then pour it into the empty cups you'll drink from, and from there into the pot. Each pour into a room-temperature vessel cools it by roughly 10–20°F (5–10°C), so two pours from the boil lands you close to the right range. It also warms the cups.
Cold brew (mizudashi)
Put about 10 g of sencha in 17 oz (500 ml) of cold water and refrigerate for 3–6 hours. Cold-brewed sencha is sweet, savory, and almost free of bitterness. In Japan it's a summer staple.
Can you re-steep Sencha?
Yes, and the second steep is often the best. The leaves are already open, so the second infusion needs only about 15–30 seconds, with water a few degrees hotter. A third steep at about a minute brings out a more astringent, refreshing cup. Pour every infusion out completely so the leaves don't sit in water between steeps.
Ways to drink Sencha
Fukamushi (deep-steamed) sencha
Steamed two or three times longer than regular sencha. Dark, rich, and less astringent, with a cloudy green liquor. It steeps faster, so try 45–60 seconds.
Shincha
The first harvest of the year, sold fresh in spring. Sweet, bright, and low in bitterness. Brew it slightly cooler and treat it as a seasonal treat.
Kabusecha
Sencha shaded for about a week before harvest, which makes it sweeter and more savory, between sencha and gyokuro. Brew it a little cooler than regular sencha.
