DH Filter Basket 58mm - Medium-dark Roast Optimized

Engineered for dark roasts. Built to unlock sweetness, not bitterness.

The MHW-3BOMBER DH Filter Basket is the result of extensive research and prototyping specifically targeting medium-dark and dark roasted coffee. Where standard baskets over-extract darker roasts into bitterness, the DH's low extraction rate, triple hole size design, and concentric crisscross arrangement slow and control the flow — drawing out sweetness and texture while leaving harshness behind.

Key Features:

• Dark Roast Optimized | Low Extraction Rate: Specifically engineered for medium-dark and dark roasted beans — the low extraction rate prevents over-extraction of bitter compounds while maximising sweetness and body. The result is a smoother, more balanced cup that honours the character of darker roasts rather than fighting it.
• Triple Hole Size | 0.2mm / 0.25mm / 0.3mm: Three distinct hole diameters work together to adjust flow rate and pressure distribution across the puck — finer holes slow the flow in critical zones, larger holes maintain volume. More even, more controlled brewing than a single-diameter basket can achieve.
• Concentric Equidistant Crisscross Arrangement | 580 Holes: 580 holes arranged in a precise concentric equidistant cross pattern ensure consistent pressure and flow across the entire basket surface — reducing channelling, promoting uniform extraction of coffee oils and flavour compounds from edge to centre.
• Straight Flat Bottom | No-Groove Design: The groove-free, straight flat bottom ensures even water distribution across the grounds from the first moment of extraction. Fully compatible with flat-base tampers and dosing tools — a cleaner, more efficient workflow with no dead zones.
• AISI304 Stainless Steel | Professional Grade: Food-grade AISI304 stainless steel construction — corrosion-resistant, durable, and built for daily professional use. Available in Silver, Black, Gold, and Multicolor.

How the DH Compares:

• DH Filter Basket — 580 holes, crisscross concentric arrangement, 0.2/0.25/0.3mm, low extraction rate → medium-dark & dark roasts, enhances sweetness & texture
• BEP Filter Basket — 745 holes, matrix array, 0.16/0.55mm, high extraction rate → enhances flavor sweetness
• DEX Filter Basket — 872 holes, matrix array, 0.27mm, high extraction rate → medium & medium-dark roasts
