How Much Caffeine Is in Sencha?
Sencha is Japan's everyday steeped green tea. A standard 8 oz cup using 2 g of leaves at 175°F for 1 minute delivers roughly 25-35 mg of caffeine — about a third of a cup of coffee and less than half a bowl of matcha.
About 30 mg per cup — a gentle lift, well below coffee.
How it compares
Sencha gives you enough caffeine to notice, paired with L-theanine, for smooth afternoon focus. It's the daily-drinker of Japanese tea culture precisely because the caffeine profile is modest enough to drink multiple cups without overdoing it.

Frequently asked
Does steeping sencha longer add more caffeine?
Yes, slightly — but past the 1-2 minute mark you mainly extract bitter tannins. The caffeine peaks early. Longer steeps make the tea less pleasant, not significantly more caffeinated.
Does cold brew sencha have less caffeine?
Yes. Cold water extracts roughly half as much caffeine as hot water over a 6-hour steep — one reason cold-brew sencha is popular for hot-weather sipping.
