Is matcha caffeinated? This is a common question and we’ve seen it advertised as caffeine free at some cafes. That is not true. It’s universal that we know green tea has caffeine. Same goes for matcha. More so for matcha. Matcha is basically, the whole green tea leaf, grounded into a fine powder and consumed. A standard serving of matcha is 2g per drink but we can see people consuming 4 - 5g per drink. A standard espresso is 145mg of caffeine per 50ml cup* according to Food Standards AU and NZ.
