CASABREWS 51mm Bottomless Portafilter with Puck Screen & 3-Ear Wood Espresso Handle for CM5418 & 3700 Essential

Elevate Your Espresso Craft at Home

Designed for 51mm baskets, the CASABREWS 51mm Bottomless Portafilter delivers a snug, secure fit that supports consistent extraction across shots. This bottomless model is compatible with CASABREWS CM5418 and 3700 Essential machines, offering a seamless upgrade path for your setup without forcing changes to your routine.

The kit includes practical tools to streamline your workflow and sharpen technique:

• Double shot filter basket for typical home espresso dosing
• 51mm puck screen to keep the brew head cleaner and promote even extraction

Built for durability and comfort, the portafilter body is crafted from food-grade stainless steel with a hand-polished finish. The solid wood handle provides an ergonomic grip, giving you control and a premium feel during each pull.

The bottomless design offers direct visibility into the extraction, allowing you to observe stream progression and detect issues like channeling. This setup helps you fine-tune grind size and tamping pressure, turning adjustments into real-time learning opportunities rather than guesses.

Practical tips for best results include starting with freshly ground coffee and considering a finer grind for bottomless shots. A common starting point is a 16 g dose for a double espresso, with even tamping and the puck screen used to maintain a clean brew head.

In real-world use, you might be dialing in a new roast, experimenting with a lighter profile, or simply refining your morning routine. The goal is to support better visualization of extraction and more consistent shots, while recognizing that outcomes depend on multiple variables like grind, dose, and tamping technique.

Care, Fit, and Practical Notes

Rinse after use, avoid harsh abrasives, and store with the puck screen in place to maintain performance. The 51mm diameter is designed to work with standard baskets, and the three-ear design helps distribute pressure evenly for a steady, repeatable pull.
