If you have access to a coffee scale or a kitchen scale to measure your coffee grounds and water, follow the ratio below for optimal enjoyment. Coffee quantity is measured in grams of ground coffee and water is measured in grams or millilitres.

If you don't have a precision scale you can use common kitchen utensils such as tablespoons to measure a coffee to water ratio that will result in a great cup of coffee.
Tablespoons range from 4g to 7g. For simplification, we averaged a tablespoon to 5 grams of ground coffee. We are also using an 8oz (240ml) cup as a standard cup of coffee.
