The Complete Sencha Guide

Introduction

Sencha accounts for approximately 75% of all tea produced in Japan, making it the nation's signature everyday beverage. Despite this ubiquity, sencha quality spans an enormous range — from simple bancha-grade leaves to competition-winning lots that rival gyokuro in complexity.

Steaming Depth

The steaming duration fundamentally shapes sencha's character. Asamushi (light steaming, 15-30 seconds) preserves the leaf's needle shape and produces a clear, bright liquor with a clean, refreshing taste. Chumushi (medium steaming, 30-60 seconds) balances clarity with body. Fukamushi (deep steaming, 60-120 seconds) breaks down cell structure, creating a cloudy, deep green liquor with a thick, rich body and reduced astringency. The fine leaf particles in fukamushi extract quickly — just 30-45 seconds — and produce a more viscous mouthfeel.

Regional Character

Shizuoka (40% of production): The heartland of Japanese tea. Middle elevation, moderate climate. Produces balanced, approachable sencha with grassy sweetness. Kagoshima (30% of production): Volcanic soil in southern Kyushu produces bold, robust sencha with higher caffeine content. Earlier harvest season due to warmer climate. Uji (Kyoto): The prestige region, producing the most refined sencha with exceptional umami and floral complexity. Small volume, premium pricing.

Cultivars

Yabukita dominates at 75% of planted area, valued for its balance of flavor, yield, and frost resistance. Saemidori produces sweeter, more amino-acid-rich tea. Okumidori develops later, extending the harvest season. Asatsuyu creates intensely umami-rich, almost gyokuro-like sencha.

Brewing Method

Warm your kyusu with hot water and discard. Add 5g of sencha, pour 150ml of water at 70-75 C, and steep for 60-90 seconds. Pour every drop from the pot — the last few drops are the most concentrated and flavorful. Second infusion: same temperature, 30 seconds. Third infusion: 80 C, 45 seconds.
