Blue Star Coffee Lower Shower Puck Screen   €9.99

I bought this without expecting too much, and hoping it would make my pucks less susceptible to channelling. Having tried it I am amazed at the difference it made:

1) Less channelling 2) More uniform shots 3) Better tasting shots 4) Easier clean-up

The screen definitely improves pre-infusion and puck stability if the portafilter is inserted before raising the lever. I get less channelling and better tasting shots. These screens are definitely now a standard part of my work flow. Highly recommended!

I use this as a contact shower screen which not only helps stop any coffee particles getting stuck on the main shower screen but it also allows for a much more evenly soaked puck with less channelling so you get a more even extraction.
Expertly made piece of kit!

Very thin so it allows use of a shallow basket but still very effective. I have a Bezzera machine with a BZ group, so the baskets are actually shallower then with an E-61 group. This screen makes it possible.

This thing is excellent for people who prefer a cleaner shower screen.
I've used cotton discs but they don't fit perfectly. This metal is dense and fits like a glove inside my basket.

, very quick turnaround of orders and a really great selection of stock

This has made a massive improvement to my espresso extraction on my beko cep5152b. Cheap machine which I've switched to unpressurised basket and naked portafilter. Was getting a pretty deep centre channel in my puck due to the 15bar pressure and only 1 hole behind the shower screen. This has almost completely eliminated that and my espresso tastes a LOT better.

Dislike: every time you should get it or will lose if didn't remember..in the knock box

The espresso always flows beautifully out of the bottomless portafilter. No channeling. Also, the the top shower screen stays super clean. Winner.
