Thank you for the article Daniel. I had one question what is the quantity of water in ml that you use while cupping. Thank you in advance.

Hi Venu!

Theoretically you can use any quantity of water. As long as the ratio of coffee to water is correct, you can use any size cup you have on hand.

That said, the two most popular sizes — and I use both — are 150 ml (about 5.5 ounces), and 250 ml (just over 8 ounces). I like the slightly larger sizes. That size is the typical white porcelain bowl you see in many cupping labs. The smaller ones are often transparent "rocks glasses," like you serve whiskey in. Either size can work.

If you use smaller cups, the only concern is to make sure you have enough liquid for everyone to cup thoroughly. With just two or three cuppers, there's no issue, but in a large group cupping it pays off to use larger cups.

For 150 ml cups, I use 8 - 8.5 grams of coffee. For 250 ml cups, I use about 12 grams of coffee. The more precise the better, obviously, but if you are within half a gram, you'll be fine.


Thank you Daniel
