A ristretto is a short shot of espresso that can be made in two ways: by restricting the extraction time, or by restricting the extraction flow. The result is a sweeter drink with a more intense flavor.

Instructions
Finely grind 7-9 grams of coffee beans to an espresso grind size. The grind size should be slightly finer than what you would use for your normal espresso.
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 15 to 18 seconds.
You should get about 0.5 to 0.8 fluid ounces of espresso. If you get considerably more than that, grind your coffee finer. If you get too little coffee, grind your coffee slightly coarser.
