Highest Caffeine Teas
20 teas · 30–50mg caffeine/100ml
The teas in this ranking represent the highest naturally occurring caffeine levels in the tea world. Shade-growing (as practiced in gyokuro and matcha production) increases caffeine by forcing the plant to compensate for reduced photosynthesis. Young buds and leaves also contain more caffeine than mature leaves, which is why tippy teas often rank higher.
Understanding caffeine content helps tea drinkers make informed choices — whether seeking a morning energy boost or a gentle afternoon cup without sleep disruption.
