Does Mint Tea Have Caffeine? The Complete Guide

A 240 ml cup of pure peppermint or spearmint (an herbal mint infusion) contains 0 mg of caffeine.

• Peppermint and spearmint herbal tea: 0 mg per 240 ml (caffeine-free).
• Moroccan mint brewed with green tea: roughly 28 mg per 240 ml (green tea base).
• Black tea comparison: 47 mg per 240 ml; drip coffee: 96 mg per 240 ml.
• FDA recommends a daily caffeine limit of 400 mg for healthy adults; pregnancy guidance ~200 mg.

Caffeine in different types of mint tea

“Mint tea” is a category, not a single ingredient. Pure mint infusions (peppermint, spearmint) are herbal teas and contain no caffeine: the dataset entry “Herbal tea (caffeine-free)” is 0 mg per 240 ml. When mint is blended with a true tea leaf (Camellia sinensis), the cup inherits that tea’s caffeine.

Common pairings and what they mean for caffeine

• Pure peppermint/spearmint: 0 mg (herbal).
• Mint blended with green tea (e.g., Moroccan mint): green tea level — 28 mg per 240 ml.
• Mint with black tea: black tea level — 47–50 mg per 240 ml depending on blend (dataset lists black tea 47 mg, English Breakfast 50 mg).

Quick comparison table: mint teas versus other drinks

Peppermint tea: why it’s caffeine-free

Peppermint and spearmint are not Camellia sinensis; they’re aromatic herbs. USDA FoodData Central and common tea databases classify these as herbal tisanes and list them as caffeine‑free (dataset: herbal tea 0 mg/240 ml). That makes them a reliable choice if you want mint flavor without stimulant effects.

Spearmint and specialty mint blends

Spearmint behaves like peppermint: pure spearmint infusions are 0 mg. Specialty commercial blends sometimes add black or green tea for body and color—always check the label. If the ingredient list names green tea, use 28 mg per 240 ml as a practical baseline (USDA / FoodData Central numbers).

Moroccan mint tea: the caffeine caveat

Traditional Moroccan mint is typically gunpowder green tea steeped with fresh mint. Because the base is green tea, assume the caffeine is the same as green tea: 28 mg per 240 ml. If a café makes a stronger concentrate or uses multiple teabags, caffeine will rise accordingly.

What affects caffeine in mint blends

Key variables: tea base (herbal vs. Camellia sinensis), number of tea bags, steep time, water volume, and serving size. Longer steeping and more leaf mass pull more caffeine from Camellia sinensis leaves — labels with plain “mint tea” can mean either 0 mg (herbal) or a nonzero value if blended with real tea.

Caffeine decay: how long mint‑tea caffeine stays active

Use a population-average half‑life of 5.7 hours: caffeine roughly halves every 5.7 h. Below are concrete remaining amounts at 3, 6, 9 and 12 hours for typical initial doses (percentages: ~69% at 3 h, ~48% at 6 h, ~33% at 9 h, ~23% at 12 h).

Health, safety, and timing

FDA guidance cites 400 mg/day as a general upper limit for healthy adults; during pregnancy many authorities (including some guidance summarized by Mayo Clinic and EFSA) recommend limiting caffeine to about 200 mg/day. The American Academy of Pediatrics advises caution for adolescents. Pure mint herbal teas let you enjoy hot or iced mint without contributing toward those limits.

Sleep considerations

Even modest caffeine from a green‑tea mint blend (28 mg) can remain measurable overnight — our decay table shows ~13 mg after 6 hours and ~6 mg after 12 hours. If you’re sensitive, avoid green/black tea–based mint in the late afternoon.

Special situations

Children, pregnant people, and those with arrhythmias or anxiety should ask a clinician about limits. If medication interactions are possible, consult a professional. This page is informational, not medical advice.

How to be sure: read labels and track intake

When in doubt, check the ingredient list: “peppermint” or “spearmint” alone = caffeine‑free; “green tea,” “black tea,” “mate,” or “matcha” = contains caffeine and use dataset benchmarks (green tea 28 mg /240 ml, black tea 47–50 mg /240 ml, matcha 70 mg). For accurate daily totals, track drinks in an app like CoffeeLog to sum milligrams across beverages and snacks.

If you want a mint flavor with zero caffeine, choose certified herbal mint or rooibos‑mint blends. If you enjoy a caffeine lift, opt for Moroccan mint or mint black tea and be mindful of steep and serving size.

How do I estimate caffeine when mint is mixed with matcha, yerba mate, or other caffeinated bases?

If mint is added to a caffeinated base, the cup’s caffeine equals the base’s caffeine; mint itself contributes 0 mg. For example, a 240 ml mint-matcha made with 1 tsp matcha will contain the matcha amount — 70 mg per 240 ml — and no extra caffeine from the mint, according to USDA FoodData Central.

A mixed mint brew is a beverage that combines mint (flavoring) with a separate caffeinated tea or powder.

Use the dataset numbers for each caffeinated base and add them; matcha (1 tsp) is 70 mg per 240 ml and yerba mate is 85 mg per 240 ml, both listed in USDA FoodData Central. If you make a 240 ml mint matcha and a 240 ml mint yerba mate, the two cups together are 70 mg + 85 mg = 155 mg total caffeine; write those milligrams into a tracker so you can compare to your daily limit.

If a recipe mixes two bases (for example, matcha plus brewed green tea) sum both base values from the dataset — green tea is 28 mg per 240 ml, per USDA FoodData Central — and scale by serving size. For a 360 ml blended drink made from 240 ml matcha (70 mg) diluted to 360 ml, scale proportionally: 70 mg × (360/240) = 105 mg of caffeine in the serving.

See the site’s matcha and yerba mate guides for common serving templates: Matcha: Does Matcha Have Caffeine? and Yerba Mate: Complete Caffeine Guide provide practical recipes and their typical mg counts.

How should I log mint tea so I stay under my safe daily limit?

Log mint beverages by milligrams: add the mg for each caffeinated base and treat pure peppermint or spearmint as 0 mg. Use the FDA 400 mg/day benchmark for healthy adults and the EFSA 200 mg/day pregnancy guidance when relevant.

A caffeine log is a running tally of caffeine in mg from all beverages and foods.

Step 1: pick a source of truth and record mg each time you drink; the dataset numbers on this site (USDA FoodData Central values) are convenient benchmarks. Step 2: add mg across the day — for example, two 240 ml Moroccan mint cups (28 mg each per USDA FoodData Central) are 28 + 28 = 56 mg; add a 240 ml drip coffee (96 mg per USDA FoodData Central) to reach 56 + 96 = 152 mg. Step 3: compare that total to the FDA’s 400 mg/day recommendation (U.S. Food and Drug Administration) or to EFSA’s 200 mg/day pregnancy limit (EFSA 2015 opinion).

Use the site’s calculator tools to speed this up: the caffeine half-life calculator can estimate mg left over at a given time, and the safe daily limit tool adjusts recommendations by body weight. Logging in mg rather than “cups” prevents surprises when blends or sizes change.

If I switch from caffeinated mint to herbal peppermint, how quickly can withdrawal symptoms start?

Withdrawal can begin within about 12–24 hours after you stop consuming a typical daily caffeine amount and often peaks within the first 24–48 hours, according to the site’s withdrawal guide. Replacing a morning 240 ml drip coffee (96 mg per USDA FoodData Central) with pure peppermint (0 mg) can therefore trigger withdrawal in that timeframe for a regular consumer.

Caffeine withdrawal is a syndrome of headache, fatigue, and mood changes that follows abrupt reduction in habitual caffeine intake.

The site’s Caffeine Withdrawal Guide summarizes onset and typical duration; consult that page for symptom timelines and stepwise tapering strategies. If you aim to avoid withdrawal, taper by reducing daily mg gradually — for example, replace one 240 ml caffeinated mint (28 mg) with herbal peppermint, then reduce other sources over several days while tracking mg.

Can I get a similar energy boost from mint tea — how many cups equal one cup of drip coffee?

To match one 240 ml cup of drip coffee (96 mg per USDA FoodData Central) with Moroccan mint (green tea base, 28 mg per 240 ml, USDA FoodData Central) you would need roughly 3.4 cups of Moroccan mint. To match drip coffee with black-tea-based mint (47 mg per 240 ml, USDA FoodData Central) you need about 2 cups.

A caffeine-equivalent is the number of standard cups of one beverage needed to equal the caffeine in a reference drink.

Arithmetic examples: drip coffee 96 mg ÷ Moroccan mint 28 mg = 3.43, so about three to four 240 ml Moroccan mint cups equal one 240 ml drip coffee. For black-tea mint: 96 mg ÷ 47 mg = 2.04, so roughly two cups. If you prefer matcha-mint, 96 mg ÷ 70 mg = 1.37, so one large matcha-mint will deliver most of the coffee’s caffeine. Use the site’s caffeine half-life calculator or caffeine comparison pages to compare servings and plan consumption.

How late can I drink a 240 ml Moroccan mint and still expect to fall asleep by 11:00 PM?

If you drink a 240 ml Moroccan mint (28 mg per USDA FoodData Central) at 5:00 PM (six hours before an 11:00 PM bedtime), about 13 mg will remain in your system at 11:00 PM using a 5.7-hour half-life model. For many people that residual is small, but individuals vary in sensitivity.

First-order elimination is a decay process where the remaining amount halves with time according to a half-life.

We use a population-average half-life of 5.7 hours (342 minutes) for first-order elimination; Mayo Clinic notes caffeine’s half-life typically ranges about 3–7 hours (Mayo Clinic). The math: remaining mg = initial mg × 0.5^(hours/5.7). For 28 mg at 6 hours: 28 × 0.5^(6/5.7) = 28 × 0.463 ≈ 13 mg remaining. If you want near-zero remaining (<6 mg) at bedtime, avoid a 28 mg cup less than ~12 hours before bed, because 28 × 0.5^(12/5.7) ≈ 6 mg. Use the last cup before bed tool to tailor timing to your schedule and sensitivity.

Bottom line

Pure peppermint and spearmint herbal infusions contain 0 mg of caffeine per 240 ml (USDA FoodData Central), so they provide mint flavor without stimulant effects. When mint is blended with a true tea leaf, the cup inherits that tea’s caffeine: Moroccan mint (green tea base) is 28 mg per 240 ml and black-tea mint generally tracks the black tea value (~47 mg per 240 ml), both per USDA FoodData Central. The U.S. Food and Drug Administration recommends 400 mg/day as a general upper limit for healthy adults (FDA) and the European Food Safety Authority advised a 200 mg/day pregnancy limit in 2015 (EFSA).

Caffeine leaves the body by first-order elimination with a population-average half-life of 5.7 hours (342 minutes); Mayo Clinic reports typical half-life ranges of about 3–7 hours (Mayo Clinic). Use the decay formula remaining = initial × 0.5^(hours/5.7) to estimate mg left at bedtime: for one 240 ml Moroccan mint (28 mg), expect ~19 mg after 3 hours, ~13 mg after 6 hours, ~9 mg after 9 hours, and ~6 mg after 12 hours. If you want the stimulant effect, choose a caffeinated base (matcha 70 mg, yerba mate 85 mg per 240 ml, USDA FoodData Central); if you want no stimulant, choose pure peppermint/spearmint (0 mg per 240 ml, USDA FoodData Central).
