Description

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

MHW DH 18g Filter Basket: 58mm Iridescent is engineered to elevate extractions with dark roasted coffee beans, using a unique triple-aperture crisscross design that improves flow dynamics, balances puck pressure, and enhances sweetness in every shot.

Optimised Filtration for Dark Roast Espresso

The DH Filter Basket is crafted for baristas seeking precision with medium-dark to dark roasted beans. Featuring a flat bottom with 580 laser-perforated holes in three aperture sizes—0.2mm, 0.25mm, and 0.3mm—it allows for better pressure balance across the puck, leading to fewer channeling issues and a richer extraction. The iridescent finish brings a distinct, eye-catching aesthetic to any coffee station.

How the MHW DH Iridescent Filter Basket Works

  • Crisscross Aperture Layout: Designed to increase pressure on the outer puck while easing flow through the centre, improving extraction balance.
  • Three-Layer Hole Arrangement: Approx. 580 holes arranged concentrically in equidistant circles—136 x 0.3mm, 164 x 0.25mm, and 280 x 0.2mm.
  • Flat Bottom Design: Compatible with most tamping tools and ideal for achieving an even distribution and tamp.
  • 18g Dose Reference: Designed for an approx. 18g dose, ideal for dark roast espresso profiles.

Key Features of the MHW-3BOMBER DH Filter Basket

  • 580 laser-perforated holes: Triple aperture layout designed for improved extraction flow.
  • Crisscross pattern alignment: Enhances flow rate balance and pressure stability.
  • Flat-bottomed with no grooves: Maximises compatibility with tamping tools and improves contact with coffee grounds.
  • Ideal for medium-dark and dark roasts: Specifically tuned for enhanced sweetness and reduced bitterness in darker coffee profiles.
  • Iridescent finish: Adds a premium aesthetic with a striking multi-tone surface.
  • Compatible with most 58mm espresso machine portafilters: Fits standard E61-style group heads and others with matching specs.
  • Durable AISI304 stainless steel: Corrosion-resistant and built to withstand high-pressure brewing.

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 thoroughly after each use.
  • Use a soft brush to remove coffee residue from the holes.
  • Avoid abrasive materials that could damage the iridescent finish.

Best Practices for Brewing

  • Grind Size: Start with a slightly finer grind for better pressure control.
  • Tamping: Use even pressure to take full advantage of the flat-bottom design.
  • Dose: 18g is a good reference point but adapt based on roast profile and flavour goal.
  • Flow Monitoring: If you notice uneven flow or splashing, adjust distribution or try a WDT tool.

Questions and Answers

  • What differentiates the DH Filter Basket from standard filter baskets?
    The MHW DH Filter Basket uses three different hole diameters in a crisscross arrangement to better balance puck pressure, slow channeling, and optimise flow for medium-dark to dark roasts.
  • Is the DH Basket compatible with all 58mm portafilters?
    It is compatible with most 58mm espresso machine portafilters, including E61 group heads. However, always check the dimensions before purchasing.
  • What dose should I use with the DH 18g Filter Basket?
    It is optimised for 18g doses, but you can adjust it based on your roast level, grind size, and desired extraction profile.
  • Can I use this filter basket for light roasts?
    While specifically tuned for darker roasts, you can experiment with light roasts, but expect a different flavour balance and flow dynamic.
  • Does the iridescent finish affect flavour or performance?
    No. The finish is cosmetic and does not interfere with extraction or coffee flavour.

Review and Coffee Parts Thoughts

The MHW-3BOMBER DH Filter Basket in Iridescent is not just about style; it’s engineered to improve the extraction profile of darker roasts, with a three-tier aperture design that enhances flow and flavour balance. This model is ideal for baristas wanting more sweetness and less bitterness from their medium-dark espresso shots. If you're dialling in darker blends with precision grinders or pairing with distribution tools, the DH basket gives you control and consistency. For best results, pair with an aligned 58mm tamper and explore how puck dynamics shift across roast levels.
