Aluminum Espresso Tamper · 58 mm

A tilted or loose puck lets water rush through the low spots, so the shot runs unevenly and tastes thin even with good beans.

This aluminum tamper has a flat 58 mm base that presses a firm, level bed of coffee in standard 58 mm baskets. Rest the portafilter on a tamping mat, press straight down, then give a light twist to polish the surface before you lock it in.

It is a core tool for any machine that takes a 58 mm portafilter. Measure your basket first, since some machines use 51 to 54 mm instead.
