Question: how much caffeine in coffee bean matcha latte?
Answer: 2 tsp to 1 tablespoon serving (for the equivalent of a 12 to 16 oz mug) will give you 38-54mg of caffeine. If you have a smaller portion, (8 to 12oz) cup of Matcha Chai, then you will use probably 1 1 /2 tsp, which would give you around 28mg of caffeine.
