MHW-3BOMBER DH 18g Filter Basket: 58mm Silver

The MHW DH 18g Filter Basket in Silver is engineered for medium-dark and dark-roasted beans. Its multi-aperture design ensures smoother extractions and richer flavours, enhancing every shot with greater clarity and balance.

How the MHW DH 18g Filter Basket Works

This filter basket features a three-tier aperture pattern (0.2mm, 0.25mm, 0.3mm) arranged in equidistant concentric circles. The smaller outer holes increase puck resistance to slow flow, while the larger inner apertures improve centre flow. This pressure balance reduces channeling and improves flavour consistency in darker roast extractions.

Specifications

  • Capacity: Approx. 18g (based on internal testing)
  • Material: AISI304 stainless steel
  • Total Holes: Approx. 580
  • Hole Sizes: 0.2mm, 0.25mm, 0.3mm
  • Inner Diameter: Approx. 58.5mm
  • Outer Diameter (Top): Approx. 70mm
  • Height: Approx. 24mm
  • Colour: Silver
  • Compatibility: Most 58mm commercial espresso machines

Key Features of the MHW DH 18g Filter Basket

  • ✅ Three Aperture Sizes: 580 holes total with 0.2mm, 0.25mm, and 0.3mm diameters for optimised flow.
  • ✅ Crisscross Pattern: Uniformly spaced for stable puck resistance and even extraction.
  • ✅ Flat, Groove-Free Base: Enhances compatibility with tampers and dosing tools.
  • ✅ Tailored for Dark Roasts: Reduces bitterness and enhances sweetness with dark roast beans.
  • ✅ Pressure-Zone Balance: Inner and outer zones regulate flow differently to prevent channelling.
  • ✅ AISI304 Stainless Steel: Anti-corrosion, oxidation-resistant, and built to last.
  • ✅ Fits Most 58mm Portafilters: Compatible with standard commercial espresso machine handles.

Comparison & Performance Insights

When tested against a standard basket using the same dark roast coffee, the DH Filter Basket produced:

  • Higher sweetness with reduced bitterness.
  • More balanced mouthfeel with improved textural clarity.
  • Lower extraction rate (19.02% vs 19.64%) but better flavour yield.
  • Lower TDS (9.78% vs 10.1%), reflecting a cleaner cup.

The result? A more nuanced and syrupy espresso—especially when dealing with darker roast profiles.

Maintenance & Cleaning

  • Rinse after each use and backflush weekly to maintain optimal performance.
  • Slight polish marks from production are normal and do not impact function.
  • Safe for both café and home environments.

Best Practices for Brewing

  • Pair with medium-dark to dark roasts for best results.
  • Use even distribution tools for maximum extraction efficiency.
  • Ideal for baristas using 58mm commercial machines.

Questions & Answers

  • Is the MHW DH Filter Basket compatible with all 58mm portafilters?
    Yes, it fits most standard 58mm espresso machines and portafilter handles. Always check basket depth clearance for precision fit.
  • Does the 18g marking refer to exact capacity?
    No. The 18g refers to a specification standard. The actual dose may vary slightly depending on grind size and bean density.
  • What makes it ideal for dark roasts?
    The multi-aperture design moderates flow and reduces pressure inconsistencies, helping bring out more sweetness and less bitterness from darker beans.
  • Is it suitable for light roast extractions?
    While it can be used for lighter roasts, it's optimised for medium-dark and dark roast profiles due to its flow control dynamics.
  • Can it improve flavour and texture?
    Yes. Tests show increased sweetness, reduced bitterness, and a smoother mouthfeel versus standard filter baskets.

Review and Coffee Parts Thoughts

The DH 18g Filter Basket in Silver provides a tangible difference for baristas looking to optimise extraction from medium-dark and dark roast beans. Its crisscross flow structure is intelligently designed for pressure balance and flavour enhancement. We’ve tested it with machines like the Rocket and Rancilio Silvia and found improved sweetness and smoother finishes. Explore our full filter basket collection for other compatible options.
