What Is Matcha? The Complete UK Guide for Beginners

What is matcha?

Matcha is a finely stone-ground powder made from specially shade-grown green tea leaves. Unlike regular green tea, where you steep the leaves and discard them, matcha means you're consuming the entire leaf, every nutrient, every bit of flavour, everything. It originated in China during the Song Dynasty but was refined into the drink we know today by Japanese Buddhist monks in the 12th century.

The word itself is simple: "ma" means ground, "cha" means tea. Ground tea. That's exactly what it is, though the process behind it is far more involved than the name suggests. Matcha has been central to Japanese tea ceremony (chanoyu) for centuries, and over the past decade it's become one of the most popular drinks in the UK, turning up in everything from lattes to croissants.

How is matcha made?

The process starts roughly six weeks before harvest, when tea plants (Camellia sinensis) are covered with shade structures that block around 90% of sunlight. This forces the leaves to overproduce chlorophyll and L-theanine, the amino acid responsible for matcha's signature umami flavour and calm-focus effect.

After hand-picking in spring, the leaves are briefly steamed to halt oxidation, then dried and stripped of stems and veins. What remains is called tencha, the raw material unique to matcha. This tencha is slowly ground between granite stone mills, producing just 30–40g per hour per mill, according to the Nihon Tea Association. That painstaking pace is what keeps the powder so fine (5–10 microns) without generating heat that would damage the flavour.

It's an extraordinary amount of effort for a small tin of powder, which is partly why quality matcha costs what it does.

Why is matcha different from regular green tea?

You're drinking the whole leaf, not just a brew. With standard green tea, sencha, gunpowder, jasmine, you pour hot water over leaves, extract a fraction of their compounds, then bin the leaves. With matcha, you whisk the stone-ground powder directly into water, so you ingest 100% of the leaf's nutrients.

According to a study published in the Journal of Chromatography A, matcha contains up to 137 times more epigallocatechin gallate (EGCG), a potent antioxidant, than standard brewed green tea. That's a staggering difference from a single change in preparation.

The shade-growing process also sets matcha apart. Regular green tea is grown in full sun, which makes leaves higher in catechins but lower in L-theanine. Matcha's extended shading flips that ratio, giving it a richer, sweeter, more umami-forward flavour profile. They come from the same plant, but the experience is completely different. For a deeper comparison, see our matcha vs coffee breakdown.

What does matcha taste like?

Good matcha tastes umami-rich, gently sweet, and vegetal, think fresh grass, steamed spinach, and a savoury depth that lingers on the tongue. There shouldn't be any harsh bitterness. If your matcha tastes aggressively bitter or dusty, it's either low quality or you've used water that was too hot.

Ceremonial grade matcha from the first spring harvest (ichiban-cha) tends to be the smoothest and sweetest, with a creamy mouthfeel. Culinary grades lean more astringent and robust, which is exactly what you want when the flavour needs to punch through milk or sugar in a matcha latte.

Temperature matters enormously. Brewing at 70–80°C rather than boiling water reduces bitterness significantly. The colour is your first clue to quality: vibrant, electric green signals freshness and proper shade-growing. Dull, yellowish-green suggests oxidation or a lower grade. Trust your eyes before you even taste it.

What are the three main grades of matcha?

Matcha is broadly divided into three grades: ceremonial, latte (sometimes called premium), and culinary. The difference comes down to leaf quality, harvest timing, and intended use.

Ceremonial grade uses the youngest leaves from the first spring harvest. It's the finest, brightest, and most expensive, typically £25–£50 for 30g at retailers like Amazon UK or specialist shops. Drink it straight with water.

Latte grade sits in the middle. It's slightly more astringent, holds its flavour beautifully in milk-based drinks, and usually costs £15–£30 for 30g. You'll find decent options at Holland & Barrett and Waitrose.

Culinary grade is the most robust, designed for baking, smoothies, and cooking. It's the most affordable at around £8–£20 for 50–100g, widely available at Tesco and Sainsbury's.

None of these grades is officially regulated by a single governing body, they're industry conventions. Our ceremonial vs culinary guide breaks down these terms in more detail.

How do you get started making matcha at home?

You need four things: matcha powder, a bowl (or mug), a bamboo whisk (chasen), and water at around 75°C. That's genuinely it. A basic chasen costs £8–£12 on Amazon UK and makes a noticeable difference compared to a fork or regular whisk, it creates the frothy, lump-free consistency that makes matcha enjoyable.

Here's the simplest method:

1. Sift 1–2g of matcha (roughly half a teaspoon) into your bowl to remove clumps.
2. Add a splash of 75°C water (about 30ml) and whisk briskly in a W-shaped motion for 15–20 seconds until a fine foam forms.
3. Top up with another 60–80ml of hot water, or switch to steamed milk for a matcha latte.

If you don't have a thermometer, boil your kettle and let it sit for 3–4 minutes, that gets you close to 75°C. Start with a latte-grade matcha if you're new to the taste; it's forgiving and not too expensive while you find your feet.

Which matcha should beginners buy in the UK?

Start with a latte grade from a reputable brand, it's versatile enough to drink straight or mix into lattes, and it won't sting your wallet if you decide matcha isn't for you. Expect to spend around £15–£25 for your first 30g tin.

Look for matcha that states its origin (Uji, Nishio, and Kagoshima are well-regarded Japanese regions), has a vibrant green colour in product photos, and comes in an opaque, airtight tin. Avoid anything in clear packaging, light degrades matcha rapidly.

Good starting points are available at Holland & Barrett, Waitrose, and Amazon UK. For a more detailed rundown with specific product picks and taste notes, head to our best matcha powder UK guide. Once you've found a latte grade you enjoy, it's worth trying a ceremonial grade to experience how smooth and sweet matcha can be at its best.

How should you store matcha to keep it fresh?

Matcha has three enemies: light, heat, and air. Once opened, keep your tin sealed tightly and store it in the fridge, not the cupboard. An opened tin of matcha is best used within four to six weeks, as the powder oxidises quickly once exposed to air, losing both its vibrant colour and delicate flavour.

Unopened tins last considerably longer. Most quality brands suggest consuming within six to twelve months of the production date, though flavour peaks in the first few months. If your matcha has turned from bright green to olive or yellowish-green, it's past its prime, still safe to drink, but better suited for baking or smoothies than drinking straight.

Never freeze matcha. Condensation from temperature changes introduces moisture, which clumps the powder and accelerates degradation. A sealed tin at the back of your fridge is the sweet spot.

Frequently asked questions

What does matcha taste like?

Quality matcha tastes umami-rich, naturally sweet, and gently vegetal, like fresh grass with a creamy, savoury depth. It shouldn't be harshly bitter. Bitterness usually means the water was too hot (stay around 75°C) or the matcha is low grade. Ceremonial grade is the smoothest; culinary grade is more robust and astringent.

Is matcha the same as green tea?

No. Both come from the same plant (Camellia sinensis), but matcha is shade-grown, stone-ground into a fine powder, and whisked into water, meaning you consume the entire leaf. Standard green tea is steeped and the leaves are discarded. According to research in the Journal of Chromatography A, matcha delivers up to 137 times more EGCG antioxidants than regular brewed green tea.

Does matcha have caffeine?

Yes. A typical 2g serving of matcha contains roughly 60–70mg of caffeine, similar to a small cup of coffee, according to the European Food Safety Authority. However, matcha also contains L-theanine, which promotes calm alertness rather than the jittery spike many people experience from coffee. See our full matcha vs coffee comparison.

What do I need to make matcha at home?

At minimum: matcha powder, a bowl or mug, a bamboo whisk (chasen), and hot water at around 75°C. A chasen costs £8–£12 on Amazon UK and is well worth it for a smooth, frothy result. A fine-mesh sieve for sifting is also helpful. You don't need expensive equipment to make great matcha, just good technique and decent powder.

What is the difference between ceremonial and culinary matcha?

Ceremonial grade is made from the youngest, first-harvest leaves, producing a smooth, sweet powder meant for drinking straight with water. It typically costs £25–£50 for 30g. Culinary grade uses later-harvest leaves, tastes more robust and astringent, and is designed for baking, smoothies, and cooking, usually £8–£20 for 50–100g. Latte grade sits between the two. See our ceremonial vs culinary guide for a full breakdown.

Can you drink matcha every day?

Most people can, yes. At one to two servings a day (2–4g of powder), matcha is widely considered safe for healthy adults, according to the European Food Safety Authority's guidelines on caffeine intake. It provides a steady source of antioxidants, L-theanine, and gentle energy. If you're pregnant, breastfeeding, or sensitive to caffeine, check with your GP before making it a daily habit.
