Caffeine in tea: the honest ladder from herbal to matcha

Ranked honestly, caffeine in tea is a four-rung ladder. Rooibos and most herbal infusions sit at zero. White teas and roasted or twig greens like hojicha sit low. Most everyday teas — sencha, Earl Grey, oolongs, mate — cluster in the middle. And a small top shelf — matcha, shaded gyokuro, Assam-style breakfast blacks — sits highest. The same leaf can land in different places depending on how much you use, how hot your water is and how long you steep, which is exactly why we publish levels instead of milligrams.

Why levels, not milligrams

Milligram charts look scientific and disagree with each other constantly, because a 'cup of green tea' is not one thing: double the leaf or double the steep and you have changed the number. So our catalog rates each of its 140 teas on a relative scale from 0 to 3, as prepared the way that tea is normally prepared. It is a reading you can actually act on — dots, not decimals — and it can never contradict a tea's own page, because it is the same data.

The ladder, rung by rung

Level 0 — nothing at all: rooibos, chamomile, peppermint, hibiscus and most herbal blends. This is the largest group in our catalog — 45 teas — which makes caffeine-free evenings easy to furnish. One honest note: 'decaf' black or green tea is not level 0; trace caffeine always remains.

Level 1 — light: white teas like Pai Mu Tan, and the gentler side of green — roasted hojicha, twig kukicha, rice-cut genmaicha, everyday bancha. Comfortable afternoon territory.

Level 2 — the everyday middle: sencha, Earl Grey, most oolongs, shou pu-erh and yerba mate. This is where most of the catalog lives — 67 of the 140 teas.

Level 3 — the top shelf: matcha (you drink the whole powdered leaf, not an infusion of it), gyokuro (shading the plant concentrates its strength), Assam, English Breakfast and Darjeeling, young sheng pu-erh. Eighteen teas earn this rung.

Two results surprise almost everyone. White tea is not the lowest — our whites sit at level 1, a rung above the herbal zero. And 'green tea' spans three rungs, from kukicha at 1 to sencha at 2 to gyokuro and matcha at 3: processing and growing decide the rung; leaf color barely predicts it.

Working the ladder in practice

Mornings take care of themselves — levels 2 and 3 are natural there. The afternoon is where the ladder earns its keep: stepping down to level 1 keeps the ritual without the buzz, and our guide to low-caffeine teas for the afternoon has specific picks. As a rule of thumb, shorter steeps and cooler water also extract less caffeine from the same leaf. And if caffeine tends to cost you sleep, make everything after mid-afternoon a level 0 and browse the full catalog by goal for evening cups you will actually look forward to.

One last honest note: the ladder is a starting point, not a verdict. Your own sensitivity, your teaspoon and your steep time all tilt it. Read it as a map for the day — the louder rungs while the sun is high, the quiet ones as it sets — and let your evenings tell you where your personal cutoff lives.
