Instructions
Turn on the espresso machine so the boiler heats up
Finely grind 7-9 grams of coffee beans to an espresso grind size.
Place the coffee grounds in the filter-basket.
Slightly knock the portafilter on the counter to pack and level them. If you have an espresso leveler, use it to perfectly level your coffee puck.
Tamp the coffee grounds with a considerable amount of pressure. When you are done tamping, there should be about 3-4 mm from the basket's edge to the coffee puck.
Lock the portafilter in the espresso machine, and switch the brew button ON.
Pull your shot for about 20 to 25 seconds.
You should get about 1 fluid ounces of espresso. If you get considerably more than 1 oz. grind your coffee finer. If you get too little coffee, grind your coffee slightly coarser.
