Hojicha Caffeine: How Much Is in Each Cup (and Why It Varies)

How much caffeine is in hojicha?

Hojicha contains approximately 7 to 30mg of caffeine per 8oz (240ml) brewed cup. This wide range reflects genuine variation across products and brewing methods.

For context: - Hojicha (8oz brewed): 7 to 30mg - Sencha (8oz brewed): 30 to 50mg - Matcha (2g serving): 60 to 80mg - Black tea (8oz brewed): 40 to 70mg - Coffee (8oz drip): 95 to 200mg - Decaf coffee (8oz): 2 to 15mg

Hojicha is one of the lowest-caffeine teas available, comparable to some herbal teas and significantly lower than any caffeinated coffee. It is not caffeine-free, but the amount is low enough that most people can drink it in the evening without sleep disruption.

Why hojicha is low in caffeine

Two factors explain hojicha's low caffeine content:

1. Roasting degrades caffeine The roasting process exposes tea leaves to temperatures around 200 degrees Celsius. Caffeine is relatively heat-stable, but prolonged high-heat roasting does degrade some caffeine. Research by Goto et al. (1996) found that roasting reduces caffeine content in green tea, with darker roasts producing greater reductions.

2. Stems and twigs contain less caffeine than leaves Hojicha is often made from bancha (later-harvest leaves) or kukicha (stems and twigs). Caffeine is synthesized primarily in young leaves and is present in lower concentrations in stems and twigs. A hojicha made predominantly from stems (kukicha-style) will have less caffeine than one made from leaves.

The combination of these two factors -- roasting plus stem-heavy material -- produces a tea with very low caffeine content.

What affects hojicha caffeine content

The 7 to 30mg range is wide because several variables affect the final caffeine content:

Roasting degree: - Lighter roasts retain more caffeine - Darker roasts degrade more caffeine - Most commercial hojicha is medium to dark roast

Leaf vs stem ratio: - Leaf-based hojicha (bancha): higher caffeine - Stem-based hojicha (kukicha): lower caffeine - Blended products: intermediate

Brewing parameters: - Water temperature: hotter water extracts more caffeine - Steep time: longer steeping extracts more caffeine - Leaf-to-water ratio: more leaves per cup increases caffeine

Typical hojicha brewing: 90 to 95 degrees Celsius water, 30 to 60 second steep, 3 to 5g per 8oz. Adjusting these parameters can shift caffeine content within the range.

If you are specifically trying to minimize caffeine, choose a stem-based (kukicha) hojicha, use a shorter steep time, and use cooler water.

Hojicha caffeine vs matcha caffeine

The caffeine difference between hojicha and matcha is substantial:

Matcha (2g serving): - Caffeine: 60 to 80mg - L-theanine: 25 to 46mg - Effect: calm, focused alertness from the caffeine plus L-theanine combination

Hojicha (8oz brewed): - Caffeine: 7 to 30mg - L-theanine: low (roasting degrades L-theanine; no shade-growing) - Effect: minimal stimulation

Matcha contains roughly 3 to 10 times more caffeine than hojicha. More importantly, matcha's L-theanine content modulates the caffeine effect, producing the calm-focus experience. Hojicha lacks both the caffeine and the L-theanine to produce this effect.

For people switching from coffee who want to reduce caffeine intake gradually, hojicha is a useful intermediate step -- lower caffeine than matcha, but still a warm, comforting beverage with some caffeine.

Hojicha caffeine vs coffee caffeine

Compared to coffee, hojicha has dramatically less caffeine:

- Drip coffee (8oz): 95 to 200mg - Espresso (1oz shot): 63mg - Hojicha (8oz brewed): 7 to 30mg

Even a weak cup of drip coffee contains 3 to 10 times more caffeine than hojicha. This makes hojicha a genuinely low-caffeine alternative for people who want to reduce their caffeine intake significantly.

However, hojicha does not replicate the coffee experience. It has a toasty, nutty flavor rather than coffee's roasted bitterness, and it provides minimal stimulation. People who switch from coffee to hojicha for caffeine reduction should expect a significant change in both flavor and energy effect.

Is hojicha safe during pregnancy?

Hojicha's low caffeine content makes it one of the more pregnancy-compatible teas, but it is not caffeine-free.

The American College of Obstetricians and Gynecologists (ACOG) recommends limiting caffeine to less than 200mg per day during pregnancy. A single cup of hojicha (7 to 30mg) is well within this limit.

However, caffeine half-life increases significantly during pregnancy -- up to 15 hours in the third trimester, compared to approximately 5 hours in non-pregnant adults. This means caffeine accumulates more readily during pregnancy.

For pregnant individuals who want to minimize caffeine, hojicha is a reasonable choice compared to coffee or matcha. Consulting a healthcare provider about specific caffeine limits during pregnancy is always appropriate.

Note: this is general information, not medical advice. Individual circumstances vary.

Hojicha caffeine and sleep

Hojicha's low caffeine content makes it suitable for evening consumption for most people. With 7 to 30mg of caffeine and a 5-hour average half-life, a cup of hojicha at 8pm would leave approximately 3.5 to 15mg of caffeine at midnight -- a negligible amount for most adults.

For comparison, a cup of matcha at 8pm would leave 30 to 40mg at midnight, which can meaningfully disrupt sleep architecture even if you do not feel subjectively awake.

People who are highly caffeine-sensitive (slow CYP1A2 metabolizers) may still notice effects from hojicha's caffeine, but for most people, hojicha is a practical evening beverage.

If you are trying to completely eliminate caffeine before bed, herbal teas (chamomile, rooibos, peppermint) are caffeine-free alternatives.
