Bottomless Portafilter + Walnut Handle - E61 / La Marzocco / ECM

See every shot. Fix every flaw. Pull better espresso.

The MHW-3BOMBER Bottomless Portafilter is the single most effective diagnostic tool in espresso preparation. Without a spout to hide the extraction, every channelling issue, uneven tamp, and distribution flaw becomes immediately visible — giving you the feedback to fix it. SUS304 food-grade stainless steel head, 100% natural walnut wood handle, and machine-specific sizing for Breville/Sage, DeLonghi La Specialista, La Marzocco, and E61 grouphead machines.

Key Features:

• Bottomless Design | Real-Time Extraction Feedback: The open basket base exposes the full extraction as it happens — uneven flow, channelling, and off-centre drips are instantly visible. An essential diagnostic tool for dialling in distribution, tamping pressure, and grind size. Indispensable for beginners learning technique and experienced baristas chasing consistency.
• SUS304 Food-Grade Stainless Steel Head: Precision-machined from food-grade SUS304 stainless steel — corrosion-resistant, hygienic, and built for daily professional use. Maintains dimensional accuracy for a consistent, leak-free seal with your grouphead.
• 100% Natural Walnut Wood Handle: Solid walnut wood handle provides a warm, premium grip with natural texture for confident handling during extraction. Elegant, durable, and a step above standard plastic or composite handles.
• Machine-Specific Sizing | Precise Fit: Available in four machine-specific variants — each engineered for the exact ear configuration and basket diameter of your machine. No adapters, no compromises, no leaks.
