Fogkay 51mm Bottomless Portafilter for Casabrews CM5418 – 3-Ear, Puck Screen, Wood Handle

Overview

The Fogkay 51mm Bottomless Portafilter is designed to pair with CASABREWS machines like CM5418, 3700Essential, and 5418Pro. With a three-ear mount and a precise 51mm fit, this open-bottom filter offers a window into your extraction, helping you observe flow, saturation, and potential channeling as you brew.

What’s Included

• A 51mm stainless steel filter basket with a 2-cup capacity (up to 16 g of coffee).
• A 51mm puck screen to promote even water distribution and keep the group head clean.

Key Build and Materials

• Head: food-grade stainless steel, polished to a bright, durable finish for a secure group head fit.
• Handle: natural solid wood, designed for a comfortable, stable grip during manual extraction.
• Detachable design for quick disassembly, making cleaning and maintenance straightforward.

Why It Matters in Practice

Using a bottomless portafilter can reveal the espresso’s flow pattern and extraction dynamics. While results depend on grind, dose, and tamping, this model provides a practical tool for observation and technique refinement without changing the machine’s core setup.

Tips for Best Results

• Use fresh beans and grind to a finer setting to improve extraction control.
• Employ a WDT tool and a 51mm distributor to break up clumps and achieve even bed distribution.
• Tamp evenly and monitor flow visually to minimize spurts and channeling during release.

Compatibility and Fit

Check that your original portafilter is 51mm in diameter with three ears (approximately 4 mm thick each). This ensures a snug fit and reliable performance with the CM5418, 3700Essential, and 5418Pro lines.

Note: This portafilter is designed to be a replacement option. While it offers clear benefits for skilled home baristas, achieving perfect shots may require practice and adjustment to your grinder and technique.
