The Normcore Spring-Loaded Tamper V4 is a coffee tamper with a spring inside that sets the tamping pressure. The V4 improves the central shaft design. The interchangeable springs now apply pressure directly to the coffee grounds through the central shaft.
A leveling plate rests flat on the rim of the filter basket, so the tamp lands level without judging it by eye. To tamp, press down and turn clockwise at the same time. The plate stops further travel once it contacts the basket, which keeps tamp depth repeatable.
Three springs (15 lb, 25 lb and 30 lb) are included, so you can choose the pressure you prefer. The 25 lb spring comes installed. The tamper is available in several diameters to fit different espresso machines, such as the 53.3 mm size for 54 mm baskets and many Breville/Sage Barista Pro and Barista Espresso models. Patent pending.
