For espresso, use 7 grams of illy per shot (about 1oz). For auto-drip brewed coffee, start with 7 grams of illy per 8-ounce cup. You may need to adjust to taste as the parameters (water turbulence and temperature) of each coffee maker differ somewhat. You can take the guesswork out of espresso by using E.S.E. pre-measured, pre-tamped servings (pods).
