|Dosage, Bean to Water ratio - For coffee brewing use 0.25 to 0.3 Oz. (roughly a heaping tablespoon) of bean for every 6 Oz. of water, and for espresso use 8 to 9 grams of bean for every 35 ml of water. Adjust slightly to suit your taste.
Brew Temperature - The subject of brew temperature can be very involved, especially when extracting espresso. There are a lot of things to consider; roast degree and age, the varietal, bean origin or blend of beans, water quality, accuracy of temperature measurement, altitude, differences in tastes, etc. For the sake of simplicity, a brew temperature range between 198 and 202 degrees Fahrenheit is recommended. As a general guide for temperature adjustment, if the brew tastes on the sour side then your temperature is too low and if your brew tastes burnt or harsh then your brew temperature is too high.
