An automatic espresso machine typically uses about 2 grams of coffee per shot, so a single shot will require about 14 grams of coffee. A double shot will require about 28 grams of coffee. A quadruple shot will require about 56 grams of coffee. A typical cup of coffee is around 120 ml, so a single shot will fill a little more than half a cup and a double shot will fill a full cup. A quadruple shot will fill just over two cups. If you want to make a large pot of coffee, an automatic espresso machine can use up to 500 grams of coffee at once.
