Hojicha Tea: Complete Caffeine Content Guide
A 240 ml cup of hojicha typically contains an estimated 7–20 mg of caffeine per serving (this is an approximate range reported by beverage analyses and producers).
- Estimated hojicha caffeine per 240 ml: 7–20 mg (roasted green-tea stems/leaves reduce caffeine).
- Green tea (240 ml) contains 28 mg; black tea (240 ml) contains 47 mg — hojicha is usually much lower.
- Drip coffee (240 ml) is 96 mg63 mg — coffee delivers several times the caffeine of hojicha.
- FDA recommends up to 400 mg/day for healthy adults; pregnancy guidance is ~200 mg/day.
Caffeine levels in hojicha tea — what drives the low numbers
Hojicha is a Japanese roasted green tea made from stems, twigs, and later-harvest leaves; roasting both lowers perceived astringency and reduces extractable caffeine compared with unroasted green tea. Analytical reports and manufacturer lab values place typical brewed-cup values in the low milligram range. Because hojicha is not listed explicitly in the USDA dataset above, the commonly reported brewed range is approximately 7–20 mg per 240 ml cup; consider this an estimate rather than a single standardized value.
Comparing hojicha to other teas and matcha
Use the table below to compare common brewed-tea and coffee servings using the dataset values. Hojicha here is shown as an estimated range to reflect variability by tea grade and steeping.
| Drink | Serving | Caffeine (mg) |
|---|---|---|
| Hojicha (estimate) | 240 ml | 7–20 mg (estimate) |
| Green tea | 240 ml | 28 mg |
| White tea | 240 ml | 16 mg |
| Oolong tea | 240 ml | 37 mg |
| Black tea | 240 ml | 47 mg |
| Matcha (1 tsp) | 240 ml | 70 mg |
| Drip coffee | 240 ml | 96 mg |
| Cold brew | 240 ml | 200 mg |
| Espresso (single) | 30 ml | 63 mg |
Hojicha versus coffee — practical perspective
A 240 ml cup of hojicha (7–20 mg estimate) contains roughly 1/14th to 1/5th of the caffeine in a standard 240 ml drip coffee (96 mg). That makes hojicha a good choice when you want the warm ritual of tea with minimal stimulant effect. If you need a small, predictable lift, a single espresso (63 mg) or a cup of green tea (28 mg) is a clearer choice by caffeine delivered per serving.
Factors that affect hojicha's caffeine content
Leaf selection and harvest
Stems and later-harvest leaves — commonly used in hojicha — contain less caffeine than young leaf buds. Higher-grade hojicha made from younger leaves will trend toward the upper end of the estimated range.
Roast level
Roasting alters the tea matrix and can reduce extractable caffeine; darker roasts tend to yield lower brew caffeine than lightly roasted or unroasted leaves given identical steeping conditions.
Steeping time and temperature
Longer, hotter steeps extract more caffeine. Short, cooler steeping (e.g., 80–85°C for 30–60 seconds) reduces caffeine compared with a prolonged 3–5 minute infusion.
Leaf-to-water ratio and cup size
Stronger leaf ratios increase milligrams per cup; small concentrated servings will contain more mg per 100 ml.
How long caffeine from hojicha lasts — decay and numbers
Biological half-life for caffeine in the average adult is about 5.7 hours, so roughly half the caffeine remains after one half-life. Below are concrete remaining-mg examples using the population-average decay approximations: after 3 h ≈ 69% remains, 6 h ≈ 48%, 9 h ≈ 33%, 12 h ≈ 23%.
| Original dose (mg) | 0 h | 3 h (~69%) | 6 h (~48%) | 9 h (~33%) | 12 h (~23%) |
|---|---|---|---|---|---|
| Hojicha (low estimate) | 7 mg | 4.8 mg | 3.4 mg | 2.3 mg | 1.6 mg |
| Hojicha (high estimate) | 20 mg | 13.8 mg | 9.6 mg | 6.6 mg | 4.6 mg |
| Green tea | 28 mg | 19 mg | 13 mg | 9 mg | 6 mg |
| Drip coffee | 96 mg | 66 mg | 46 mg | 32 mg | 22 mg |
Health, safety, and timing concerns
For healthy adults, the U.S. Food and Drug Administration advises up to 400 mg/day as a generally safe upper limit; the European Food Safety Authority and Mayo Clinic cite similar guidance. Pregnancy guidance typically limits caffeine to about 200 mg/day; the American Academy of Pediatrics discourages caffeine for young children and recommends caution in adolescents. If you have heart arrhythmia, anxiety disorders, or are taking interacting medications, consult your clinician before adjusting intake.
Practical tips — brewing, cutting caffeine, and tracking
- To minimize caffeine: use stems or larger-leaf blends, steep briefly at lower temperatures, and avoid powdered or young-leaf hojicha variants.
- For a richer flavor without more caffeine, brew a slightly higher leaf-to-water ratio but shorten steep time; roast flavor gives perceived strength independently of caffeine.
- Track cumulative daily caffeine with tools like CoffeeLog to see how a cup of hojicha fits your total; logging helps avoid unintentionally exceeding recommended limits.

Frequently asked questions
Does hojicha have caffeine?
Yes. Hojicha contains caffeine but at low levels: most brewed 240 ml cups are estimated at about 7–20 mg per serving, considerably less than regular green or black tea.
How much caffeine is in a cup of hojicha compared to green tea?
A standard 240 ml green tea contains 28 mg (dataset). Hojicha is typically much lower, roughly an estimated 7–20 mg per 240 ml cup depending on leaf selection and steeping.
Will hojicha keep me awake at night?
Unlikely for most people because a hojicha cup delivers only ~7–20 mg caffeine; after 6 hours about 48% remains. Sensitive individuals should avoid consumption within several hours of bedtime.
Is hojicha safe during pregnancy?
Pregnancy guidance commonly recommends limiting caffeine to about 200 mg/day. A cup of hojicha (~7–20 mg) is low, but cumulative intake should be considered and discussed with your clinician.
Can I reduce caffeine in hojicha when brewing?
Yes. Use stems or larger-leaf blends, lower steep temperature, shorter steep times, and smaller leaf-to-water ratios to lower extracted caffeine per cup.
How can I track caffeine from hojicha and other beverages?
Log servings and amounts in a tracker such as CoffeeLog to total daily mg. Tracking prevents exceeding the FDA 400 mg/day limit for healthy adults and helps manage timing relative to sleep.
