Matcha vs Green Tea: Caffeine, Antioxidants & Which to Drink

Matcha and green tea both come from Camellia sinensis. The difference is processing: green tea is steeped leaves; matcha is the entire shade-grown leaf, ground to a fine powder and whisked into water. Because you consume the whole leaf, matcha delivers far more of everything — caffeine, catechins, and chlorophyll — per serving.

Caffeine and L-theanine: why matcha feels different

A typical 240 mL brewed green tea: ~30 mg caffeine, 6 mg L-theanine.

A 240 mL matcha (1 tsp powder, ~2 g): ~70 mg caffeine, 25 mg L-theanine.

L-theanine promotes alpha-wave brain activity (calm focus). The high caffeine + L-theanine ratio in matcha is why drinkers report a smoother, less jittery alertness compared to coffee — you get the kick without the crash.

Antioxidants: matcha is concentrated

EGCG (epigallocatechin gallate) is green tea’s star catechin. Brewed green tea: ~70 mg EGCG per cup. Matcha: ~140–200 mg EGCG per tsp serving.

Whether you actually need that much is the question. EGCG is associated in cohort studies with modest reductions in cardiovascular disease, certain cancers, and inflammatory markers, but most studies were done on brewed-tea drinkers consuming 3–5 cups/day. Matcha at 1–2 servings/day delivers similar total EGCG with much less liquid volume.

How to prepare each properly

Green tea: 80–85 °C water (not boiling — bitter), steep 2–3 minutes, remove leaves. Boiling water destroys catechins and creates astringency.

Matcha: 80 °C water (cooler than boiling), 1 tsp powder, whisk vigorously with a chasen (bamboo whisk) or small electric milk frother for 20 seconds until foamy. No filtering — you drink the whole leaf.

Cost and quality

Green tea: $5–30 / 100 g loose leaf. Quality varies but most basic brands are fine.

Matcha: $20–80+ / 30 g. The ceremonial grade ($60+) is for drinking; culinary grade ($20–30) is for lattes, baking. Buy from a Japanese specialist (Ippodo, Marukyu Koyamaen, or local: Genmai Café in Montreal, Tea Bar in Toronto) — the supermarket "matcha" powder is often diluted with sencha and old.

The bottom line

If you want focused energy and can afford the price tag, matcha is the more concentrated option — one cup does the work of three. For everyday drinking, brewed green tea is cheaper, easier, and still excellent. Avoid both within 6 hours of bedtime.
