Questions

About these tools

What can the Matcha Almanac calculators do?

Three things: scale any bowl to your own dose, with water, temperature and milk for usucha, koicha and lattes; estimate the caffeine and L-theanine in what you have logged today; and work out what a bowl costs at home against your cafe price.

Do the calculators need an account?

No. They run in your browser, they are free, and nothing you type is sent anywhere. Your brew journal and calculator settings are stored on this device only.

How much caffeine is in a bowl of matcha?

About 68 mg for a standard 2 g bowl, at roughly 34 mg per gram of matcha. These are estimates, not medical advice.
