Matcha Lemon Mint Shot
Reader ratingsA small, frothy, vivid-green shot of whisked matcha chilled over ice with lemon and fresh mint — a calm-focus pick-me-up in three sips.
Whisked powdered green tea is the heart of the Japanese tea ceremony, where Zen monks have drunk it to stay calm and alert during long meditation since the 12th century.
Safety
- A teaspoon (2 g) of matcha holds roughly 40–90 mg of caffeine, up to about as much as a cup of coffee. Limit it if you are sensitive, pregnant or breastfeeding (most guidance caps caffeine at about 200 mg a day in pregnancy), have anxiety, palpitations or trouble sleeping, or take stimulant medicines, and avoid it within 6–8 hours of bed. Not for young children.
- Caffeine can change how your body handles some medicines, including lithium, theophylline, clozapine and antibiotics such as ciprofloxacin, so ask your pharmacist if you take any of them. Take levothyroxine on its own and wait 30–60 minutes before drinking matcha.
- You drink the whole leaf, so any lead or other metals it took up from the soil come with it. Choose a brand that publishes contaminant testing. Matcha is also one of the most concentrated sources of EGCG: one analysis found at least three times the highest values reported for other green teas. Concentrated green-tea extract supplements have caused liver injury, mostly as large doses taken fasting, while brewed tea has not, so keep to one or two shots a day, with a snack, and stop and call your doctor if you notice dark urine or yellow skin or eyes.
- Tea polyphenols cut iron absorption from a meal by half or more in a trial of polyphenol-rich drinks, so if you are iron-deficient, drink matcha between meals rather than with iron-rich food or supplements. Green tea leaf also contains vitamin K, so keep your intake steady and tell your prescriber if you take warfarin.
- Contains honey if you add it, so not for infants under 12 months. A shot is a small extra, not a substitute for a meal.
Why it’s good for you
Matcha is shade-grown green tea ground whole, so you get its L-theanine and EGCG catechins along with caffeine; mint and lemon keep it fresh and light without any added sugar.
Evidence
Limited evidence
Mostly small, early, or laboratory studies.
A 2014 meta-analysis of 11 placebo-controlled trials found theanine plus caffeine, the pair that tea supplies, improved alertness and attention-switching accuracy in the first two hours after a dose, and a 2025 systematic review of 50 trials (15 pooled) found small-to-moderate differences in reaction time and attention accuracy in the first two hours, though with wide uncertainty. A 30-person crossover trial found 200 mg of purified theanine a day for four weeks lowered anxiety, depression and sleep-problem scores in healthy adults, an amount several times what one teaspoon of matcha supplies. The trials used theanine tablets, caffeine and tea constituents, not matcha, and none tested a matcha shot.

Ingredients
Instructions
- Bring some water to a boil, then let it sit for 3–4 minutes so it falls to about 175°F (80°C). Boiling water makes matcha taste harsh and bitter.
- Sift the matcha through a small fine sieve into a small bowl or glass, pressing out any lumps with the back of a spoon.
- Add 2 oz (1/4 cup) of the hot water and whisk briskly in a zigzag, or froth with a small milk frother, for 20 seconds until a fine foam forms with no dry clumps.
- Stir in the lemon juice and the honey, if using, then add the torn mint and ice cubes and stir for 10 seconds to chill it.
- Strain into a small glass, leaving the ice behind, and drink straight away; matcha settles within a few minutes.
Tips
- No whisk? Make the paste with a splash of hot water in a jar, add the rest of the water, lemon and ice, and shake hard with the lid on for 15 seconds.
- Ceremonial or premium grade tastes smooth when drunk plain; culinary grade is cheaper but tastes bitter in a shot, so keep it for smoothies and baking.
- Add the lemon last, because acid dulls matcha’s bright green color over time. Make it fresh: it does not keep.
- Have it with a snack rather than alone on an empty stomach, and earlier in the day since it carries caffeine.
