Espresso Hand Tamper, Premium Barista Coffee Tamper with Calibrated Spring, Stainless Steel Base Tamper Compatible with Espresso Machine (51mm, black)

51 mm Tamp Base: Espresso tamper base diameter is 51 mm What Is A Spring Loaded Tamper: It uses a spring to limit the tamper pressure and bottoms out on the lip spring before the tamper spring is fully compressed. So even if you put all your weight on it you still get the same tamp force since that excess weight is diverted to the portafilter. The Difference Between Standard And Spring-Loaded Styles: When used correctly, standard and spring-loaded tampers perform the same job. Delicious coffee can be brewed with either a standard or a spring-loaded tamper. That being said, a spring-loaded tamper is often much easier to use and removes one of the many variables in the espresso puck prep process. Help Get A Espresso Puck: If you want to make the best espresso, you'll need to pack the perfect puck. A good tamp creates resistance (with evenly compacted coffee) that makes the brewing water work hard to saturate the grounds and extract all of that great coffee flavor.
