Matcha

Matcha is finely ground green tea powder. Same plant as any other green tea, Camellia sinensis, but the production diverges sharply from leaf form green tea about three weeks before harvest, and the result is a drink with several times the antioxidant load, a unique caffeine plus L theanine effect, and a place in Japanese culture that goes back 800 years. It is the only tea in the world where you consume the whole leaf, not just an infusion.

Matcha has gone from a niche speciality product on the British shelf in the early 2000s to a mainstream supermarket presence by 2026. The growth has been driven by three things: the visible vivid green cup that photographs well, the calm focused energy effect from the L theanine balance, and the matcha latte as a non coffee café default. It's also the most counterfeited tea on the market, so knowing what good matcha looks like matters.

How matcha is made

The production process is what makes matcha matcha. Three details separate it from leaf form green tea:

1. Shade growing the last 3 weeks before harvest the tea bushes are covered with bamboo or shade cloth, blocking 70 to 90 percent of sunlight. The plant responds by producing more chlorophyll (deeper green) and more L theanine (the sweet, savoury, calm focus amino acid).
2. Hand picking only the youngest, most tender leaves of the spring flush. Higher grades hand select bud and two leaves; lower grades take broader plucks.
3. Steaming and stone grinding the leaves are briefly steamed (Japanese green tea convention), then de stemmed, de veined, and slowly stone ground into a powder so fine it flows like talc.

Stone grinding is the slow step. A traditional granite mill produces about 30g of ceremonial matcha per hour. Even with modern equipment, real ceremonial grade matcha is expensive to produce, which is why a 30g tin of high grade matcha costs £20 to £40 while a 100g bag of decent loose leaf green tea costs £8.

Ceremonial vs culinary matcha

Two grades dominate the British shelf, and they're for very different uses:

The simple rule: if you're drinking it neat (with hot water and a whisk), you want ceremonial grade. If you're putting it in a milky latte, smoothie, or cake, culinary grade is fine and considerably cheaper. Don't waste ceremonial matcha in a latte, the milk and sugar mask the flavour you paid for.

How to make matcha properly

Matcha is not steeped, it's whisked. The powder is suspended in hot water rather than infused from a leaf, which is why you consume the whole tea rather than the infusion. The traditional Japanese kit is a chasen (bamboo whisk), a chawan (wide bowl), and a chashaku (bamboo scoop), but a small whisk and any bowl work fine for everyday use.

1. Sift 1 to 2g of matcha (1/2 to 1 teaspoon) into the bowl. Sifting is non optional; matcha lumps if you skip it.
2. Add 60 to 80ml of water at 70 to 80°C NOT boiling. Boiling water cooks the matcha and turns the cup bitter. See the water temperatures guide for the family by family detail.
3. Whisk vigorously in a "M" or "W" pattern for 30 to 60 seconds until a thick foam forms on top. Speed matters more than pattern; the goal is a layer of fine bubbles across the surface.
4. Drink immediately. Within 2 minutes the matcha settles and the foam breaks down. This is a now or never drink.

A common British shelf shortcut is to use a battery milk frother instead of a chasen. It's slightly less aerated than a proper bamboo whisk but for everyday brews it's perfectly fine.

Matcha latte at home

The most popular use of matcha in the UK is the latte. The proper version:

1. Sift 1 to 2g of culinary grade matcha into a glass.
2. Add 30ml of water at 75°C and whisk into a smooth slurry, no lumps.
3. Heat 200ml of milk (oat works particularly well, almond is too thin, dairy is rich and traditional).
4. Pour the milk over the matcha slurry. Stir, top with foam if you've frothed the milk.
5. Sweeten with a teaspoon of honey, maple syrup, or sugar if you want; some people drink it neat.

Iced matcha latte: same recipe but use cold milk and ice cubes. Actually one of the most refreshing drinks on a summer day, and the visual layer of bright green matcha against white milk is half the appeal.

Caffeine in matcha (the L theanine difference)

Source: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Caffeine in matcha (the L theanine difference), Matcha. Canonical: https://teas.co.uk/wiki/matcha/

Matcha caffeine is high for a green tea, around 60 to 70mg per cup, comparable to a black tea or about half a brewed coffee. The reason is simple: you're consuming the whole leaf, not just the infusion. A standard cup of green tea (which only extracts what dissolves) sits at 20 to 35mg.

What makes matcha different from coffee at the same caffeine level is the L theanine content. Shade grown tea is unusually high in L theanine, an amino acid that crosses the blood brain barrier and modulates the caffeine effect. Regular matcha drinkers describe the result as "calm focus" rather than "jittery alertness", and there's reasonable scientific evidence behind that claim, the L theanine plus caffeine combination produces measurably different cognitive effects than caffeine alone in EEG studies.

The practical effect for most drinkers: matcha gives you the morning energy of a coffee without the post coffee crash or anxiety. For more on the caffeine context across all tea families, see the ultimate caffeine guide.

How to spot good matcha

The matcha quality scam is rampant. Lower grade matcha sold at premium prices is everywhere on the British shelf, and visual + sensory checks are the only way to tell.

• Colour real ceremonial matcha is a vivid, almost neon green. Yellow green or olive green matcha is older, lower grade, or both.
• Origin Japan (Uji, Nishio, Kyoto) is the gold standard. Chinese matcha is often acceptable for culinary use but rarely matches Japanese quality at ceremonial grade. Be sceptical of unmarked origin matcha.
• Taste real matcha is slightly sweet with a savoury umami undertone and minimal bitterness. Sharply bitter or fish pond grassy matcha is poor quality.
• Sift test ceremonial matcha sifts cleanly with no clumps; culinary matcha clumps slightly.
• Foaming real ceremonial matcha foams up to a thick top layer with 30 seconds of whisking. Poor matcha barely foams.

A note on health

Matcha has been studied more than most green tea preparations. The most interesting finding is the L theanine plus caffeine combination, which does seem to produce a calmer, steadier alertness than caffeine alone. Beyond that the honest picture is modest: a nutrient dense, low calorie drink with small benefits, not a cure for anything.

The "matcha boosts metabolism by 40 percent" type claims are typical supplement industry exaggeration. Drink matcha because you like it; the traditional uses are real but not magic.
