What is matcha, and does it really carry more caffeine than coffee? In short, it’s a finely milled powder made from shade-grown Japanese green tea leaves, whisked whole into water or milk rather than steeped and strained like ordinary tea. A single serving typically delivers 25mg to 70mg of caffeine, which sits below the 75mg to 200mg found in a standard coffee, not above it. That one fact alone clears up one of the most common mix-ups among coffee shop owners, office managers, and home baristas sizing up matcha as a new menu item.
Confusion tends to creep in because matcha gets lumped together with standard green tea, despite different growing methods, grades, and preparation needs. Ceremonial and culinary grades behave quite differently behind a bar, and picking the wrong one leads to bitter, chalky drinks that put customers off rather than winning them over.
This guide walks through what matcha actually is, how it’s grown and processed, what it tastes like, and how its caffeine content compares with coffee in practical terms. We’ll also cover whether matcha is good for you, how ceremonial and culinary grades differ, and how to build a matcha latte that holds up during a busy service. We stock matcha powder along with the bamboo whisks, sieves and electric whisks needed to prepare it properly, so the practical side is covered too.
Key Takeaways
- Matcha is whole, shade-grown tea leaf ground into powder, not an infusion you steep and discard, so drinkers get the full leaf’s nutrients in every cup.
- A serving carries roughly 25mg to 70mg of caffeine, less than coffee’s 75mg to 200mg, though L-theanine spreads that energy out more evenly over time.
- Expect a sweet, umami, grassy flavour with a creamy texture once whisked properly, and treat bright green colour as a reliable quality marker.
- Ceremonial grade suits traditional whisked bowls, while culinary grade copes better with milk, ice, and baking where other flavours are also in play.

What Is Matcha?
Matcha is a finely ground powder made from shade-grown green tea leaves, grown in Japan and processed specifically so the whole leaf can be consumed rather than steeped and thrown away. The plant itself is Camellia sinensis, the exact same species used for standard green tea, black tea, and oolong, so the difference comes entirely from cultivation and processing rather than a separate crop. Roughly three to four weeks before harvest, growers cover the tea bushes with shade cloth or bamboo screens, cutting direct sunlight and forcing the plant to work harder for energy. That stress response raises chlorophyll levels, which is why matcha carries such a deep green colour compared with sun-grown teas, and it also boosts amino acids, particularly L-theanine, while increasing caffeine concentration within the leaves themselves.
After harvest, the leaves are steamed to stop oxidation, dried, and stripped of stems and veins, leaving only the tender leaf material known as tencha. Tencha is then stone-ground into an extremely fine powder, a slow process that can take an hour or more per 30 grams to avoid heat damage from friction. The result is a product where drinking a bowl of matcha means consuming the entire leaf, not just the compounds that dissolve out during a few minutes of steeping, which is the reason matcha delivers a more concentrated dose of nutrients, caffeine, and flavour than a brewed cup made from the same amount of leaf. Japan has refined this process for centuries, with matcha forming the centrepiece of the traditional tea ceremony long before it reached coffee shop menus or office kitchens in the UK, and understanding that lineage helps explain both its pricing and its position as a premium beverage category rather than a simple green tea variant.
How Is Matcha Different From Regular Green Tea?
The core difference comes down to consumption method and cultivation. Regular green tea is steeped as loose leaves or bags and then removed, so you only extract what dissolves into the water during brewing. With matcha, the whole leaf is ground and drunk, and it also goes through a shading period that standard green tea rarely receives, which concentrates caffeine and amino acids further. Because you swallow the leaf itself, researchers study matcha more like a food than an infusion, including what it releases during simulated digestion.
How Is Matcha Made?
Matcha production starts with shade-growing, where tea plants destined for matcha are covered for 20 to 30 days before the first spring harvest, blocking most direct sunlight. This triggers the plant to increase chlorophyll production to capture whatever light remains, deepening the leaf’s green colour, while simultaneously raising L-theanine and caffeine levels as the plant adjusts its chemistry under stress. Growers harvest only the youngest leaves and buds during this first flush, since older, tougher leaves produce a coarser, less refined powder.
Once picked, the leaves move through a defined sequence before they become the powder you see on a shelf:
- Steaming, which halts oxidation and locks in the bright green colour before any fermentation can begin, unlike black tea, which is deliberately oxidised.
- Drying and sorting, with stems and larger veins removed to leave only the tender leaf material known in the trade as tencha.
- Stone-grinding, where traditional granite mills grind slowly and deliberately, since the friction of faster grinding generates heat that can damage the delicate compounds built up during shading.
Producing just 30 grams of high-grade matcha can take an hour or more on a traditional stone mill, which is one reason premium matcha costs more than loose green tea of similar origin. Japan’s matcha output has grown sharply over the past decade, rising from roughly 1,430 tonnes in 2012 to around 4,176 tonnes in 2023, with more than half now exported to markets including Europe. For buyers, understanding this production chain, shading, harvesting, steaming, de-stemming, and stone-grinding, explains why genuine matcha carries a price premium over bagged green tea and why sourcing from reputable Japanese regions matters for consistent quality.
Why Does Grinding Method Affect Quality?
Grinding speed and temperature directly shape the final texture. Fast mechanical grinding builds up heat through friction, which can scorch delicate amino acids and flatten flavour before the powder ever reaches a bowl. Stone-ground matcha, by contrast, stays cool throughout, preserving the fine, almost silky particle size that whisks into a stable foam rather than settling as grit at the bottom of the cup.
What Does Matcha Taste Like?
What does matcha taste like? Good quality matcha delivers a naturally sweet, umami-rich flavour with grassy, almost spinach-like notes and a faint hint of seaweed. That savoury depth comes from the high concentration of L-theanine built up during shade-growing, which softens the bitterness that sun-grown green teas can carry. Properly whisked, matcha also develops a creamy, almost frothy mouthfeel rather than tasting thin or watery.
Colour tells you a lot before you even taste it. Bright, almost luminous green signals careful shading, fresh stock, and correct storage, while a dull, yellowish, or brownish tint usually points to older leaves, poor processing, or powder that has sat too long in a hot kitchen. Staff pouring matcha for customers can use colour as a quick, visual quality check during service.
Lower grades taste noticeably more bitter and grassy on their own, which is fine once milk, ice, or sugar enter the mix but less forgiving in a straight bowl. Higher grades taste rounder and sweeter without additions, which is why cafés often stock one powder for traditional service and a separate, hardier blend for lattes and iced drinks.
Does Matcha Have Caffeine? Matcha vs Coffee Caffeine
Yes, matcha does have caffeine, though less of it than a typical cup of coffee despite what some marketing suggests. A standard serving of prepared matcha carries between 25mg and 70mg of caffeine, depending on the grade and how much powder goes into the bowl, compared with roughly 75mg to 200mg in an average cup of coffee. That puts matcha above a standard brewed green tea, which usually sits around 25mg to 50mg per cup, but clearly below coffee on a like-for-like basis.
The headline number only tells half the story, though, since matcha also carries a high concentration of L-theanine, an amino acid that slows how quickly the body absorbs caffeine and tempers the sharp spike in alertness that coffee can produce. In practice, that means matcha tends to deliver a steadier lift that builds gradually and fades more gently, rather than the quick jolt and later dip some coffee drinkers experience. This combination is one reason office managers running wellness-focused refreshment programmes often add matcha alongside coffee rather than instead of it, giving staff a gentler afternoon option without cutting caffeine entirely.
For coffee shop owners, it is worth being upfront with customers about this difference, since some assume matcha matches or beats espresso for caffeine strength when the opposite is usually true. Preparation strength matters too, since a thicker, more traditional koicha-style bowl uses roughly double the powder of an everyday usucha serving, pushing caffeine toward the higher end of that 25mg to 70mg range.
Matcha vs Coffee: A Quick Comparison
The table below sets out the practical differences side by side for quick reference.
| Factor | Matcha | Coffee |
|---|---|---|
| Caffeine per serving | 25mg to 70mg | 75mg to 200mg |
| Energy pattern | Gradual, sustained release thanks to L-theanine | Faster onset, can crash |
| Flavour | Sweet, umami, grassy | Bitter, roasted |
Is Matcha Good For You?
Is matcha good for you? Matcha packs a dense nutritional profile because drinking the whole leaf means consuming compounds that would otherwise stay behind in discarded tea leaves. It contains high levels of catechins, particularly epigallocatechin gallate or EGCG, an antioxidant that researchers continue to study; one recent paper measured the antioxidant activity of matcha extracts at different brewing temperatures.
Beyond catechins, matcha delivers chlorophyll, the compound responsible for its colour, along with measurable amounts of potassium, iron, and calcium. L-theanine, already discussed for its effect on caffeine absorption, is also linked to calmer, more sustained focus, which is part of why matcha has built a following among people managing long workdays.
None of this makes matcha a cure for anything, and it should sit alongside a varied diet rather than replace one. For operators, the honest line is that matcha offers a nutrient-dense, lower-caffeine alternative to coffee with genuine antioxidant content, which is a fair and defensible claim without straying into medical territory.
Ceremonial vs Culinary Matcha: Which Grade Do You Need?
Ceremonial grade and culinary grade matcha are not strict legal categories, but the distinction is useful shorthand for matching a product to its job. Ceremonial grade comes from the youngest first-flush leaves, ground to the finest texture, and is intended to be whisked with hot water alone in a traditional bowl with nothing added to mask its flavour. It carries a brighter green colour, a smoother, sweeter taste, and a higher price, often £15 to £30 for a small 30-gram tin, reflecting the limited leaf selection and slower processing involved.
Culinary grade, sometimes called premium grade, comes from slightly more mature leaves and carries a more assertive, grassier flavour that holds its own once milk, ice, sugar, or other ingredients enter the drink. This makes culinary grade the more practical choice for matcha lattes, iced matcha, smoothies, and baking, where the powder is one ingredient among several rather than the entire point of the drink. Choosing the wrong grade in either direction creates problems, since ceremonial grade in a sugary iced latte is an expensive way to mask a delicate flavour, while culinary grade whisked alone in a traditional bowl can taste harsh and overly bitter.
For independent coffee shops and office kitchens stocking more than one matcha product, a sensible approach is keeping one ceremonial-style powder for straight drinks or premium menu items and one hardier culinary blend for everyday milk-based service. Grade labels vary between brands, so our Japanese matcha powder guide explains what to look for on the packet. Given the matcha shortages affecting producing regions such as Uji and Nishio in recent years, having a reliable supplier who can source consistent batches also reduces the risk of running out mid-season.
How Is a Matcha Latte Made, and Which Grade Works Best?
A matcha latte starts the same way as a traditional bowl: sift one to two grams of matcha into a bowl or jug, add a small splash of water around 80°C, and whisk briskly until smooth and lump-free before the milk goes in. Steamed dairy milk or a plant-based alternative such as oat or almond is then poured over the whisked matcha, or combined cold with ice for an iced version.
Culinary-grade powders and latte blends generally hold up better across hot, iced, and busy-bar service than ceremonial grade, since they are formulated to carry flavour through milk rather than stand alone. Our matcha latte powder guide compares the main options for higher-volume service.
A useful rule behind the bar: save ceremonial grade for drinks where matcha is the whole point, and let culinary grade do the heavy lifting wherever milk, ice, or sugar join the cup.
The Takeaway
Matcha is whole, shade-grown Japanese tea leaf ground into a fine powder, not a flavoured extract or a stronger relative of green tea. It carries less caffeine than coffee, typically 25mg to 70mg per serving against coffee’s 75mg to 200mg, though L-theanine spreads that energy out more evenly than a straight espresso shot. Expect a sweet, umami, grassy taste that leans more bitter in lower grades, with colour acting as a quick quality check behind the bar.
Ceremonial grade suits traditional bowls and premium straight drinks, while culinary grade is the practical choice for lattes, iced drinks, and baking.

Frequently Asked Questions
How much matcha powder should I use per serving?
A standard usucha-style serving uses around 1g to 2g of matcha powder, roughly half to one teaspoon, whisked with 60ml to 80ml of hot water. Thicker koicha preparations use closer to double that amount for a more concentrated, slower-sipped drink. For lattes, many operators start around 2g and adjust to taste once milk is added.
Can I use a regular whisk instead of a chasen?
A metal whisk can work in a pinch, but the fine bamboo prongs of a chasen break up clumps far more effectively than wider wire loops, giving a smoother result with less grit. For higher-volume café service, a small electric milk frother often handles the job faster and more consistently than manual whisking of any kind.
Why does my matcha taste bitter or chalky?
Bitterness usually comes from water that’s too hot, above roughly 80°C, which scorches the powder’s delicate compounds during whisking. A chalky texture often means the matcha wasn’t sifted before whisking, or that lower-grade or stale powder was used. Checking water temperature and sifting every time solves most of these issues.
How long does matcha powder stay fresh once opened?
Once opened, matcha generally stays at its best for a few weeks to a couple of months, depending on how it’s stored. Keeping it sealed, away from heat and direct light, and labelling the opening date helps kitchens rotate stock before quality drops noticeably.
Is matcha safe to drink every day?
For most healthy adults, daily matcha consumption sits well within normal caffeine intake guidelines, given its moderate 25mg to 70mg per serving. Because the whole leaf is consumed, sourcing from reputable suppliers who batch-test for contaminants such as heavy metals is a sensible precaution for regular drinkers.
