The short answer. Roughly 40–70 mg for a 2 g serving — between a cup of brewed tea and a single espresso. A double espresso typically has more.

What is actually in matcha

Genuine matcha has one ingredient: ground shade-grown green tea leaves. No sweetener, no colourant, no filler, no anti-caking agent. Because the whole leaf is consumed rather than steeped and discarded, the nutritional profile differs from brewed green tea.

These are typical ranges for shade-grown matcha, not a certificate of analysis for a specific lot. If your market requires exact declared values for packaged retail, tell us and we will discuss what documentation is realistically available for your order.

Caffeine, in context

A 2 g matcha latte lands roughly between a cup of brewed tea and a single espresso. The practical difference customers report is the pace rather than the amount — L-theanine occurs alongside the caffeine in shaded leaf, which is why matcha is often described as a steadier lift. That is a description of the compound profile, not a health claim.

For a bar that serves both, it is useful to know that a double espresso typically carries more caffeine than a standard matcha latte. More on the comparison in matcha vs coffee for cafés.

Allergens and dietary status

Pure matcha contains none of the major declarable allergens — no milk, egg, gluten, soy, nuts, peanuts, fish, shellfish or sesame. It is naturally vegan and, being a single-ingredient plant product processed without alcohol or animal derivatives, it is generally considered halal-suitable by nature.

On a café menu, allergens almost always come from the other components: milk and plant milks, syrups, cream products, biscuit and dessert bases. Matcha itself is usually the simplest line on the allergen matrix. Cross-contact in your own kitchen remains your responsibility to assess.

Menu copy that is accurate and still appealing:

What not to claim

The tempting lines are the risky ones. Unless your business is prepared to substantiate them under your local food-labelling rules, avoid claiming that matcha detoxifies, burns fat, boosts metabolism, prevents illness, or delivers a specific antioxidant benefit. Regulators treat these as health claims regardless of how the sentence is phrased.

MATSU sells producer-direct matcha and describes it by origin, grade, colour and use. We do not supply health claims for menus, and we would rather you did not need them — "shade-grown, stone-ground, milled recently" sells the drink honestly.

Frequently asked questions

How much caffeine is in a matcha latte?

Roughly 40–70 mg for a 2 g serving — between a cup of brewed tea and a single espresso. A double espresso typically has more.

Is matcha an allergen?

Pure matcha contains none of the major declarable allergens. On a café menu the allergens come from milk, syrups, cream and dessert bases rather than the tea.

Yes. Pure matcha is ground green tea leaf with no animal-derived ingredients or processing aids.

Can we say matcha is healthy on our menu?

We would advise against health claims — detox, fat-burning, immunity and similar statements are regulated in most markets. Describe origin, grade and process instead.

Do you provide nutritional certificates?

The figures here are typical ranges rather than lot-specific documentation. If your market requires declared values for packaged retail, contact us and we will discuss what is realistic with our producers.
