Tencha

History

Tencha (碾茶) is matcha's secret - the shade-grown, de-stemmed leaf that is ground into matcha powder. But tencha brewed whole as a leaf tea is an entirely different experience, and one that very few people outside Japan have encountered. The leaves are shade-grown under tana canopies for 20+ days (like gyokuro), then steamed and dried - but crucially, they are NOT rolled. Instead, the flat, unrolled leaves are dried in a brick oven (tencha-ro) and then de-stemmed and de-veined, leaving only the pure leaf flesh (the mesophyll). This unrolled, de-stemmed leaf is tencha. Historically, tencha existed only as a raw material for matcha production, but in recent years, a small number of producers have begun selling it as a brewing tea, revealing a flavor profile distinct from both matcha and gyokuro.

Processing

After 20+ days of shade-growing, leaves are steamed briefly to halt oxidation - similar to sencha. Here the process diverges radically: instead of rolling, the leaves are dried flat in a specialized brick oven (tencha-ro) using radiant heat. The dried leaves are then passed through machines that remove all stems, stalks, and veins, leaving only the pure leaf flesh. This is tencha - thin, flat, jade-green flakes that look like no other tea. When ground in a stone mill, tencha becomes matcha.

Tasting Notes

Appearance

Thin, flat, irregularly shaped jade-green flakes - they look like delicate green confetti rather than typical tea leaves. No stems or veins are visible. The liquor is a very pale, delicate yellow-green with a subtle golden shimmer.

Aroma

Ethereally sweet and umami-rich - like gyokuro but softer and more delicate. Notes of fresh nori, sweet cream, and a faint floral quality. The aroma is quiet and requires attention to appreciate - it whispers rather than shouts.

Taste

Unlike anything else in the tea world - extremely delicate, intensely umami, and profoundly sweet with virtually no astringency or bitterness. Because the leaves were never rolled (which breaks cell walls and releases bitter compounds), tencha produces an extraordinarily smooth, pure infusion. The mouthfeel is light and silky. The aftertaste is a clean, lingering sweetness. Drinking tencha is like hearing the melody behind matcha's full orchestral sound.

Brewing Guide

Western Style

• Leaf: 3g per 200ml
• Water: 60–70°C (140–158°F)
• Time: 2–3 minutes
• Infusions: 2–3 infusions

Gongfu Style

• Leaf: 4g per 100ml
• Water: 60°C (140°F)
• Time: 40s first, +15s each subsequent
• Infusions: 3–4 infusions

Step-by-step

1. Very cool water. Use 60–70°C water - even cooler than gyokuro. Tencha's delicacy is easily overwhelmed. Tip: Tencha has never been rolled, so there are no broken cell walls to release bitterness - but hot water can still extract it from the surface.
2. No rinse. Never rinse tencha - the first infusion contains the most delicate, precious flavors. Tip: The thin leaf flakes release flavor quickly, so even the initial contact with water is significant.
3. Gentle steep. 2–3 minutes for the first infusion. The unrolled leaves need time to hydrate and release their flavors. Tip: Use a glass vessel if possible - watching the jade-green flakes hydrate and unfurl is beautiful.
4. Taste mindfully. Tencha rewards focused attention. The flavors are subtle but extraordinarily pure - this is tea distilled to its essence. Tip: Try comparing tencha side-by-side with matcha made from the same source - the contrast is fascinating.

Health Benefits

• Exceptionally high L-theanine content from extended shade-growing - among the highest of any tea
• Rich in chlorophyll due to shade-induced overproduction
• Contains catechins and EGCG, though less is extracted than from matcha (where you consume the whole leaf)
• The high theanine-to-caffeine ratio promotes calm alertness without jitteriness
• Contains amino acids not typically found in sun-grown teas

Food Pairings

• The most delicate Japanese sweets - higashi (dry sweets), sugar-dusted yokan
• Plain steamed rice - let the tea be the star
• Fresh, mild tofu with just a pinch of salt
• White fish sashimi - tai, hirame
• Ripe melon or fresh figs - subtle natural sweetness

Buying Guide

What to look for

• Flat, thin jade-green flakes with no stems or veins visible - this is the defining visual characteristic
• Sweet, umami aroma even in dry form - should smell like high-grade shade-grown tea
• Very pale, delicate yellow-green liquor
• Uji origin is the gold standard, though Yame (Fukuoka) also produces excellent tencha

Quality indicators

• Tencha sold as a brewing tea is rare - availability itself often indicates a quality-focused producer
• The color should be vivid jade-green - dull or yellowish flakes indicate oxidation or age
• Competition-grade tencha is grown under complete shade (99%+ blocked) for 25+ days
• The best tencha comes from cultivars bred for shade-growing: Samidori, Okumidori, Asahi

Price range: $25–50 for standard, $50–100 for premium single-origin, $100+ for competition-grade

Storage: Extremely perishable - store in airtight, opaque containers and refrigerate. Consume within 2 weeks of opening. The thin, flat leaf structure oxidizes faster than rolled teas. Buy in small quantities.

Fun Facts

• Tencha is the only Japanese tea that is deliberately NOT rolled - every other Japanese green tea involves rolling as a core processing step.
• Until recently, selling tencha as a brewing tea was virtually unheard of - it existed solely as matcha's raw material. Its emergence as a standalone tea is a 21st-century development.
• The stone mills used to grind tencha into matcha produce only about 40 grams of matcha per hour - one reason matcha is so expensive.
• Tencha's drying oven (tencha-ro) is a specialized piece of equipment found almost nowhere outside Japan's matcha-producing regions.
• Drinking tencha provides a unique perspective on matcha - you taste the same leaf in a completely different form, revealing flavors that grinding and whisking obscure.
