Hojicha sits around 7 to 20 mg of caffeine per cup. A 2-gram serving of matcha sits around 38 to 89 mg. That gap is the reason most people reach for one over the other. But the popular explanation for it — "roasting burns off the caffeine" — is mostly a myth, and the differences run deeper than one number anyway. Different plant parts, different processing, different compounds in the cup. Here is the honest comparison.
What hojicha actually is
Hojicha starts as ordinary Japanese green tea — most often bancha (mature leaves and stems) or kukicha (stems and twigs) — and is then roasted over high heat, commonly cited somewhere in the 160–220°C range. Roasting changes everything you can see, smell, and taste.
The leaves turn from green to reddish-brown. The flavor shifts from grassy and vegetal to nutty, toasty, and caramel-like, and the bitterness drops away. The aroma ends up closer to roasted barley or coffee than to anything herbaceous. People who try hojicha expecting a sencha-like cup are usually surprised at how little it resembles green tea.
The caffeine gap — and why it really happens
This is the most-searched question, so it is worth getting right.
Matcha: roughly 38–89 mg per serving. Matcha is made from tencha ground into powder, and you drink the whole leaf. The main academic review (PMC7796401) measures matcha at 18.9 to 44.4 mg of caffeine per gram, which works out to about 38 to 89 mg in a standard 2-gram bowl.
Hojicha: roughly 7–20 mg per cup. Hojicha Co. reports about 7.7 mg of caffeine in a 250 ml cup. The reason is not what most blogs say. Caffeine does sublime near 178°C, but there is little solid evidence that the brief roast removes much of it — My Japanese Green Tea notes that no study has shown significant caffeine loss from the roasting itself. The real drivers are simpler:
- The leaf. Hojicha is built from bancha and kukicha. Japan's National Food Research Institute puts bancha at about 2.05% caffeine by dry weight versus sencha's 3.07%, and the stems and twigs in kukicha are lower still. Hojicha starts low before the roaster is even lit.
- The brewing. You steep hojicha and strain the leaves out. With matcha, the leaf goes into your cup. Drinking the whole leaf transfers far more caffeine than infusing it.
So the practical takeaway holds — hojicha is the low-caffeine option, comparable to a cup of decaf coffee — but the mechanism is the leaf and the brew, not the fire.
L-theanine: high in matcha, reduced in hojicha
L-theanine is the amino acid behind matcha's "calm alertness" reputation. It builds up while the plant is shade-grown — the roughly 20 to 30 days of covering before harvest that also give matcha its umami. High-grade matcha can carry up to around 44 mg of L-theanine per gram (PMC7796401, citing Unno et al.).
Hojicha has two strikes against it here. Bancha and kukicha are not shade-grown, so they begin with less L-theanine than tencha. And L-theanine is heat-sensitive, so roasting degrades some of it. The result is meaningfully less L-theanine than matcha — though "reduced," not "absent." Hojicha still contains the amino acid; it simply does not deliver the pronounced calm-focus effect that matcha drinkers describe.
Antioxidants and EGCG
Matcha's antioxidant story centers on EGCG (epigallocatechin gallate), the most abundant catechin in green tea leaves. A 2023 analysis of commercial green teas (PMC10665233) measured roughly 56.6 mg of EGCG per gram in ceremonial matcha and 50.5 mg per gram in culinary matcha — so a 2-gram serving lands in the low hundreds of milligrams.
Roasting reshapes catechins rather than simply destroying them. Work in Food Chemistry (2019) on the oligomerization of tea catechins during roasting found that heat drives free catechins, including EGCG, to bond with sugar-derived compounds and polymerize — which is part of why roasted tea is so much less astringent. The upshot is that hojicha carries far less free EGCG than matcha.
If EGCG research is part of why you drink tea, matcha is the stronger choice by a wide margin. One caveat on that research: EGCG's most dramatic health claims rest largely on in-vitro and animal studies, and human clinical evidence is still developing. See the health benefits guide for an honest breakdown.
Flavor comparison
In the cup, the two are near opposites.
Matcha tastes of umami, fresh grass, and a clean bitterness — most balanced in high-grade ceremonial versions, where consuming the whole leaf gives a real depth and a faintly sweet, frothy finish. Lower grades lean more bitter and less sweet.
Hojicha tastes roasted, nutty, and caramel-like, with almost no bitterness; some drinkers catch a chocolate-like aftertaste. It is easy to like on the first sip, which makes it a common gateway for anyone who finds green tea too grassy or astringent. Cold-brewed, it turns notably smooth and the caramel notes deepen. Both make genuinely good lattes, with very different characters.
When to choose each
Choose matcha if you want the caffeine-plus-L-theanine focus effect, you are drinking for EGCG, you enjoy umami and a little bitterness, or your tea habit lives in the morning and midday.
Choose hojicha if you are cutting back on caffeine, you want something warm in the evening without wrecking your sleep, you are serving children or older guests, or you simply prefer a mellow, roasted, low-bitterness cup.
For most people these are not rivals. Plenty of households keep both — matcha for mornings, hojicha after dinner.
How to prepare each
Matcha rewards a little care. Sift 1 to 2 grams through a fine-mesh strainer into a bowl to break up clumps. Add 70 to 80 ml of water at 70–80°C — not boiling, which scorches matcha and sharpens the bitterness — and whisk in a brisk W or M motion with a bamboo chasen until frothy. Drink it straight away.
Hojicha is forgiving. Steep 1 to 2 teaspoons of roasted leaf in water around 80°C for 30 seconds to a minute, then strain. Hojicha powder also exists, whisked like matcha for a fuller cup, and hojicha-powder lattes have become a café staple that is easy to make at home. Both teas come as loose leaf, in bags, and as powder.
What to look for when buying
For hojicha, the source leaf and roast level tell you most of what you need: bancha-based hojicha is rounder, kukicha-based (stem) hojicha is lighter and lowest in caffeine, and a darker roast pushes the toasty, coffee-like notes further. For matcha, grade and freshness matter more than the label's marketing — the buying guide covers what to read on the tin.
The comparison in one line: matcha gives you more caffeine, more L-theanine, more EGCG, and a more demanding flavor; hojicha gives you very little caffeine, a warm and friendly cup, and a reliable evening option. Both are worth keeping on the shelf.
