How Much Caffeine Is in Hojicha? (And Why It Makes Such a Good Evening Tea)

There was a stretch of my life when I wanted something warm in the evenings but kept paying for it the next morning. I tried herbal teas, warm lemon water, chamomile blends that tasted like soap. Then someone handed me a cup of hojicha. Roasty, smooth, quietly caramel-sweet. I slept just fine. That was when I learned that hojicha caffeine clocks in at just 7 to 10mg per cup — a number low enough to change the whole conversation about when and how you can drink tea.

What Is Hojicha?

Hojicha is technically a Japanese green tea, but calling it that almost misses the point. The defining step is roasting. Tea leaves or stems are fired at around 200°C, which changes their chemistry, color, aroma, and caffeine content in ways that no other tea processing method quite replicates.

Most hojicha starts as either bancha, a lower-grade green tea harvested later in the growing season when the leaves are coarser and more mature, or kukicha, which uses stems and twigs rather than leaves. In Japan, hojicha has been a household staple since the 1920s, when a Kyoto tea merchant reportedly started roasting unsold leaves to salvage them. The result was so different and so drinkable that it spread quickly. Today it is served at family tables, in restaurants, and as the quiet default for guests who might not want much caffeine.

Unlike Japan’s most widely consumed steamed green tea, which is processed to lock in its grassy freshness, hojicha goes the other direction entirely. The leaves turn reddish-brown. The brew comes out a warm amber. The flavor sits closer to toasted grain than anything you would recognize as a traditional cup of green tea.

Why Roasting Strips Away Caffeine

Here is the part most people do not expect. You might assume hojicha is low in caffeine because it comes from a lower-grade leaf, or because it is steeped differently. The real reason is more direct: high heat breaks caffeine down.

When tea leaves are roasted at around 200°C for a sustained period, caffeine molecules degrade. Not completely, but significantly enough to matter. This is different from how water temperature and steep time change what dissolves into your cup — those are extraction variables that affect the brew. Roasting is a structural change to the leaf itself. By the time hojicha reaches your teapot, the caffeine reduction has already happened in the roaster, long before hot water enters the picture.

The same high heat also sets off a process called the Maillard reaction. This is the same reaction that browns bread in an oven, develops the aroma in roasted coffee, and creates the crust on a cooked steak. In tea, it converts amino acids and natural sugars into new flavor compounds — the ones behind that toasty, slightly caramel smell that makes hojicha so immediately recognizable. It also softens the tannins and catechins that make unroasted green tea sharp and astringent. The roasted leaf is chemically different in almost every meaningful way from what went in.

Sandy’s Science Corner: Heat Does the Decaffeinating

Caffeine is relatively stable under everyday conditions, but prolonged exposure to temperatures around 200°C causes measurable thermal degradation — meaning caffeine molecules break apart under sustained heat. This is not a chemical decaffeination process. No solvents, no CO2 extraction involved. The roaster itself does the work. The same heat that gives hojicha its toasty aroma is what brings its caffeine level down so significantly compared to unroasted teas (Chacko et al., 2010).

How Much Caffeine Does Hojicha Actually Have?

A typical 8 oz cup of hojicha contains roughly 7 to 10mg of caffeine. To put that in context: a standard cup of green tea carries 25 to 50mg, matcha sits at around 70mg, black tea ranges from 40 to 70mg, and drip coffee typically lands somewhere between 95 and 150mg (Unno et al., 2017; Kochman et al., 2021).

Hojicha caffeine, in other words, is somewhere between one-sixth and one-tenth of what a morning coffee delivers. It is also considerably lower than most people expect from green teas as a category, where even the lighter options tend to sit around 25mg or more.

One thing worth being clear about: hojicha is not caffeine-free. If you have a medical reason to avoid all caffeine, it is not a direct substitute for herbal tea or rooibos. But for most people, 7 to 10mg sits well below any threshold that produces stimulation, jitters, or disrupted sleep. It is a number that tends to shift how and when people think about their tea routine.

What That Low Number Means in Practice

The practical payoff of hojicha caffeine being this low is that it opens time windows where almost every other real tea simply does not work. Evening brewing, a late-afternoon break, a warm cup after dinner without the lying-awake consequence — hojicha handles all of these without a trade-off.

Caffeine has a half-life of roughly five to six hours in the average adult, which means a cup of green tea at 6pm could still have half its caffeine circulating at midnight. How long caffeine stays active in your system varies by individual metabolism, body weight, and liver function — but with a starting point of 7 to 10mg, even slower metabolizers are working with a number that clears the sleep threshold long before bedtime. The arithmetic is forgiving no matter where you fall on the sensitivity spectrum.

This also makes hojicha a realistic daily option for people managing their total caffeine intake, those who experience anxiety or a racing heart from caffeinated drinks, older adults whose caffeine tolerance tends to drop with age, and anyone who simply wants a warm evening ritual that does not come with a cost. In Japan, hojicha is commonly offered to children and elderly guests at restaurants and family meals — not because of any formal rule, but because its gentleness is so well understood it has become the social default for those situations.

L-Theanine: Still Present, Still Working

Hojicha still contains L-theanine, an amino acid found in tea that survives the roasting process in reduced but meaningful amounts. L-theanine is the reason tea feels different from coffee even at similar caffeine doses. It does not cause drowsiness, but it takes the hard edge off stimulation and supports a calm, settled mental state without dulling your thinking.

The combination of very low caffeine and residual L-theanine is a big part of why hojicha feels genuinely calming rather than just empty or neutral. It is not the sedative heaviness of a valerian blend. It is the quiet steadiness that a good cup of tea tends to produce — just shifted further toward calm and further from alert than most teas can manage. For anyone who has noticed how L-theanine shapes the energy profile of caffeinated teas, hojicha delivers that same quality at a fraction of the caffeine load (Vuong et al., 2011).

That interaction between low caffeine and L-theanine is also part of why hojicha has been associated with better sleep quality when consumed in the evening. It is not that the tea actively puts you to sleep. It is that it does not work against the process (Unno et al., 2017).

The Rest of What Hojicha Does for Your Body

Hojicha is not widely positioned as a health tea the way matcha or unroasted green teas are, and there is an honest reason for that. The roasting process that reduces caffeine also reduces catechins, the antioxidant compounds behind green tea’s nutritional reputation. That is a real trade-off, and it is worth stating plainly rather than glossing over (Khan & Mukhtar, 2013).

That said, the picture is not empty. The pyrazine compounds produced during roasting have been associated with mild support for healthy circulation. The dramatically reduced tannin content makes hojicha significantly gentler on the stomach than most other teas. People who find green tea or black tea harsh on an empty stomach, or who experience nausea or gut discomfort from other brews, often handle hojicha without any trouble at all. And for anyone counting their daily caffeine, the low hojicha caffeine level is itself a practical health benefit — one built into the leaf by the roasting process rather than engineered out by decaffeination (Graham, 1992).

What Hojicha Tastes Like

If you have never tried it: earthy, toasty, and warm, with a quiet hint of caramel and a clean, dry finish. There is no grassiness, no astringency, none of the oceanic or vegetal notes that sometimes show up in fresh Japanese green teas. It does not taste like green tea. It does not taste like black tea either. It occupies its own lane entirely.

Hojicha made from bancha tends to be bolder and a little woodsy, with a deeper roasted character. Hojicha made from kukicha runs lighter and slightly sweeter. Both versions are approachable. Neither requires an adjustment period or an acquired taste. It is one of those teas that most people like on the very first cup, which is genuinely rare.

How to Make a Hojicha Latte at Home

The hojicha latte is where this tea finds a second gear. Its toasty, caramel-forward character pairs with milk in a way that feels completely natural — rich without being heavy, warming without becoming cloying. It also happens to be one of the easiest homemade drinks to get right on the first try.

For a hot hojicha latte, start by brewing a strong concentrate. Use 3 to 4 teaspoons of loose leaf per 6 oz of water at 95°C, steeped for about 60 seconds. Pour in 4 to 6 oz of steamed or warmed milk. Oat milk is an especially good match because its natural mild sweetness complements the roasted notes rather than competing with them. Whole dairy milk gives a creamier, richer result.

For an iced hojicha latte, brew the same concentrate, let it cool to room temperature, then pour over ice and add cold milk. A light drizzle of honey adds sweetness without masking the tea’s character. That is genuinely all it takes to produce something café-quality at home.

If you want a more concentrated, powder-style result, hojicha powder is worth seeking out. It dissolves directly into warm milk the same way matcha powder does and gives a thicker, more intense cup. Either version of a hojicha latte comes together in under five minutes and holds up well as a daily habit.

Ashley’s Note: My Evening Wind-Down

I make a hot hojicha latte most evenings now — a strong 60-second steep, warmed oat milk, nothing else added. I started doing it when I needed something that felt like a proper drink without the caffeine cost. What surprised me was how quickly it became a signal: the day is done. There is something about that roasted smell that the brain learns to associate with slowing down. If you are looking for an evening ritual that actually holds, this one is worth trying.

How to Brew Hojicha

For a plain cup, the approach is refreshingly uncomplicated. Use water at 90 to 95°C — hotter than you would use for a delicate green tea, since the roasted leaf handles heat without complaining. Steep loose leaf for 30 to 45 seconds and use about 2 teaspoons per 8 oz of water. The cup should come out a warm amber color, somewhere between pale gold and light copper.

One of hojicha’s most practical qualities is how forgiving it is. Steeping a little too long makes it stronger rather than bitter, which is rarely a problem. The temperature mistakes and timing errors that punish more delicate teas tend to go largely unnoticed here. It is a good tea for people who are still learning, and an easy one for experienced drinkers who want something low-maintenance in the rotation.

Conclusion

Hojicha does not arrive with a list of dramatic health claims or a complicated origin story. It is a roasted tea that started as a practical workaround and became, over a century, one of Japan’s most reliable everyday drinks. The low hojicha caffeine content is the reason it works for moments when everything else is off the table — the evening cup, the post-dinner ritual, the warm drink that does not come with a cost the next morning. Whether you drink it plain or turn it into a hojicha latte on a slow weekend, the experience tends to be the same: warm, uncomplicated, and quietly satisfying. That is more than enough.
