When it comes to making espresso, there are so many variables you can tinker with, and any one of them can make your shots taste wildly different from one time to the next, so nailing down consistency wherever you can is key.

Normcore's V4 tamper is one way you can at least make your puck prep more consistent.

Rather than relying on the varying degrees of strength you might employ each time you tamp — you're only human, after all — it uses a calibrated spring-loaded mechanism to ensure that the pressure applied is always the same. It also has a leveling plate that rests on the portafilter basket edge as you press down, so your pucks are consistently level.

Watch this quick demonstration video to see it in action:

The V4 comes with three interchangeable springs that allow you to adjust the pressure: 15lb, 25lb (installed by default), and 30lb.

You can get the Normcore V4 tamper for $44 on Amazon in a variety of sizes, including the most common ones:

• 51mm — Suitable for the Delonghi Dedica.
• 53.3mm — Suitable for 54mm portafilters used in the Breville Barista Express, Breville Bambino Plus, and Profitec GO.
• 58mm — Suitable for E61 machines such as the Rocket Appartamento and the Slayer Single-Group, as well as prosumer models like the Gaggia Classic Pro and Rancilio Silvia.

There are also various styles of titanium PVD coated models that run for $50–$57 each, including ones with walnut, colorful wood, and anodized bronze handles.
