Normcore Puck Screen

A puck screen disperses water more evenly across the coffee bed, which helps prevent channeling—where water finds the path of least resistance through the grounds. By ensuring the water saturates the coffee uniformly, you get a more balanced, consistent extraction.

Because it is ultra-slim at 0.8mm, it has a negligible impact on your headspace. You likely won't need to adjust your dose significantly, though you should always ensure there is enough room for the screen to sit flush on top of your tamped coffee.

You should measure the internal diameter of your portafilter basket. The Normcore puck screen is available in 58.5mm, 53.3mm, and 51mm sizes; choose the one that fits snugly inside your basket without getting stuck or leaving large gaps around the edges.

Not at all. The screen is designed for easy maintenance; you can simply rinse it with hot water after each shot. For a deeper clean, you can soak it in a solution like Cafiza periodically to remove any built-up coffee oils.

In most cases, no. However, because the screen improves extraction efficiency, some baristas find they can grind slightly finer or use a slightly higher dose. Start with your current recipe and adjust based on the taste of your shot.
