Materials & Craftsmanship

At the heart of the MHW-3BOMBER Bottomless Portafilter is a commitment to quality and purposeful design. The portafilter head is made from high-grade SUS304 stainless steel, renowned for its strength, food safety, and resistance to rust or corrosion. The handle is sculpted from solid walnut, hand-finished to preserve its natural beauty and ensure a smooth, tactile grip. Each piece is unique, with subtle variations in wood grain and color that add character—these are not defects, but hallmarks of genuine craftsmanship.

How to Use for Optimal Espresso

• Preparation: Insert your preferred filter basket into the portafilter head. Dose and distribute your coffee grounds evenly using a WDT tool or distribution tool.
• Tamping: Use a precision tamper to apply even pressure, ensuring a level coffee bed for optimal extraction.
• Extraction: Lock the portafilter into your espresso machine’s group head. Start the shot and observe the espresso flow from the open base—look for even, consistent streams with minimal channeling.
• Adjustment: If you notice spurting or uneven flow, adjust your grind size, distribution, or tamping technique. The bottomless design makes these adjustments intuitive and immediate.
• Cleaning: After use, disassemble the portafilter and rinse all components thoroughly. Dry the walnut handle immediately to preserve its finish.
