Description

MHW Espresso Puck Screen 58.5mm: Hollow Centre

MHW Espresso Puck Screen – 58.5mm Stainless Steel, 0.8mm Thick (Hollow Centre) is precision engineered to enhance extraction, preserve the brew head, and maintain coffee puck integrity for machines with groupheads featuring a protruding centre screw.

Designed for Clean, Even Extraction with Protruding Screws

This 0.8mm thick stainless steel espresso puck screen features a hollow centre to accommodate groupheads with exposed central screws. A dense mesh and smart water dispersion design delivers balanced extraction, improved flavour clarity, and effortless cleanup by preventing grounds from reaching the brew head.

How the MHW Puck Screen Works

  • Pre-Extraction Protection: Positioned over tamped grounds to act as a barrier between the puck and the group head.
  • Balanced Flow: 0.8mm thick SUS304 filter plate disperses water evenly across the bed of coffee.
  • Post-Extraction Integrity: Reduces water channeling and retains puck shape for cleaner knockouts and easier maintenance.

Questions and Answers

  • What’s the purpose of the hollow centre on this espresso puck screen?
    The hollow centre is designed for compatibility with group heads that have a central protruding screw, ensuring a flat fit across the puck without obstruction.
  • Will this puck screen help reduce channeling?
    Yes. By dispersing water evenly across the puck, it improves flow consistency and reduces channeling, especially when paired with proper distribution tools.
  • Is the 58.5mm size compatible with all 58mm portafilters?
    This puck screen is sized at 58.5mm to ensure a snug fit in most precision 58mm baskets. Always measure your basket's inner diameter for best compatibility.
  • Does it affect shot timing or flavour?
    It can slightly extend shot time while promoting a more even extraction. Many users report improved flavour clarity and less bitterness in the cup.
  • How do I clean the puck screen properly?
    Rinse under warm water after use, and use a soft brush to remove fine grounds. Avoid abrasive cleaners or dishwasher use to preserve integrity.
