Overview
If you own a Breville Bambino Plus or Barista Express, you've probably met the small heartbreak of a lovely tamper that doesn't fit. This one does. Normcore sized its 53.3 mm base for Breville's 54 mm portafilters, and lists the Barista Express, Barista Pro, Barista Touch, Bambino Plus, Infuser and Duo-Temp Pro among the machines it fits.
Calm, consistent tamping. Like its 58 mm sibling, it's self-levelling and spring-loaded. The outer guide rests on the basket so your tamp is always flat, and the spring means you simply press until it stops, with the same force every time. Three springs (15, 25 and 30 lb) let you choose how firm.
It's a big upgrade over the plastic tamper some machines ship with, and it pairs beautifully with a 54 mm dosing funnel and a WDT tool for a tidy, sweet-tasting routine.
Gentle reminder: tamping is about levelness, not muscle. Let the spring do the work, and save your energy for enjoying the shot.
