The espresso recipe is always determined by the device we use. So if we have an electric coffee maker with a shutter, we have to put so much coffee that when we push it, it reaches the line inside. Typically, this quantity is 8 to 12 grams (depending on whether we have single or double baskets). What we can adjust to these devices depending on the amount of beverage we produce. We estimate a double espresso that is about 50 to 60 grams (or a small cup of coffee). Using the the espresso pot, we put as much as we can in the baskets without pressing the coffee.
