Last reviewed by the teas.co.uk team in May 2026.

Sencha is Japan's everyday green tea, the most consumed tea in Japan, accounting for around 80% of Japanese tea production. Steamed, rolled into needle shapes, vegetal marine character with distinctive umami. The benchmark Japanese green tea; the cup that defines the category for most drinkers.

What sencha is

Sencha (煎茶) is the steamed Japanese green tea, distinguished from Chinese pan fired greens by:

Brief intense steaming (10-30 seconds) instead of pan firing
Rolling into thin needle shapes
Vivid neon green colour
Marine vegetal umami flavour profile

How sencha is made

Pluck (varies by harvest period; first flush spring is premium).
Brief withering.
Steam for 10-30 seconds (deactivates oxidation enzymes).
Roll into thin needle shapes.
Dry.

Steaming time varies, fukamushi (deep steamed, 60+ seconds) sencha has darker colour and fuller body; asamushi (lightly steamed) sencha has paler colour and more delicate character.

Sencha grades

Premium first flush sencha (shincha)

April May harvest, the year's youngest, sweetest leaves. £30-60 per 100g. Limited availability outside Japan.

Standard sencha

Year round production. £15-25 per 100g. Daily driver Japanese green tea.

Lower grade sencha (bancha)

Older, more mature leaves; later harvests. £8-15 per 100g. Affordable everyday drinking.

What sencha tastes like

Vivid green cup. Vegetal grassy character with marine umami undertones. Premium grades are sweeter; standard grades are more straightforwardly vegetal. Drunk black; milk would obliterate the character.

How to brew sencha

1 heaped tsp per 200ml.
Water at 70-80°C, NOT boiling. Boiling water bitters sencha.
Steep 1-2 minutes.
Drink black.
Premium sencha yields 2-3 infusions.

The most common British brewing mistake: boiling water + 4-minute steep. Produces bitter, harsh cup. Use cooler water and shorter time.

The temperature trick

For ideal sencha brewing without a variable temperature kettle:

Boil the kettle.
Pour boiled water into the teapot or another vessel (cools 5-10°C).
Wait 2-3 minutes (further cooling to ~80°C).
Pour over the leaves.

Sencha varieties worth knowing

Asamushi (light steamed)

Briefer steaming (10-15 seconds). Pale yellow green cup, delicate flavour, more aromatic top notes.

Chumushi (medium steamed)

Standard steaming (20-30 seconds). The everyday sencha most drinkers know.

Fukamushi (deep steamed)

Extended steaming (60+ seconds). Darker green cup, fuller body, more intense umami. Specialty.

Shincha (new tea)

First flush spring sencha. Fresh, sweet, premium. Limited season availability.

Kabuse cha (covered tea)

Sencha shaded for 1-2 weeks before harvest. Mid tier between standard sencha and gyokuro. More umami; less bitter.

Caffeine

30-50mg per 200ml cup. Standard green tea range; premium grades slightly higher.

Use cases

Daily Japanese green tea drinking.
Mid morning focus work. L theanine + caffeine combination.
Pairing with Japanese cuisine. Traditional accompaniment.
Cold brewed iced tea. Excellent. More on cold brew.
Multiple infusion drinking. Premium sencha rewards 2-3 infusions.

The L theanine + caffeine combination

Sencha is high in L theanine, the amino acid responsible for green tea's "calm alert" cognitive character. Premium sencha (especially shaded variants) has higher L theanine concentrations. More on L theanine.
