Good to Know

Everything you need to know about better espresso extraction with the OpenShot Portafilter.

  1. What is the benefit of a bottomless portafilter?
    A bottomless design lets you see espresso flowing directly from the filter basket, making it easier to spot channeling and uneven extraction. It helps you refine your grinding, distribution, and tamping technique.

  2. Will the OpenShot Portafilter fit my espresso machine?
    The 51mm OpenShot Portafilter is designed for compatible CASABREWS models, including 3700 Gense, Ultra, Ultra Pro, Ultra Max, Marenza. Always check your machine's portafilter size and locking design before purchasing.

  3. Does a bottomless portafilter improve espresso flavor?
    A bottomless portafilter doesn't automatically improve flavor, but it helps you identify uneven extraction. With better puck preparation and grind adjustments, you can achieve more balanced and consistent espresso.

  4. Why does espresso sometimes spray from a bottomless portafilter?
    Spraying is often a sign of channeling, where water flows unevenly through the coffee puck. Try adjusting your grind size, distributing the grounds evenly, and tamping consistently.

  5. What is the included 58mm puck screen used for?
    The puck screen sits on top of the coffee grounds to help distribute water more evenly across the puck. It can also reduce coffee residue on the machine's shower screen, making cleanup easier.

  6. What is included with the OpenShot Portafilter?
    Each set includes one 58mm bottomless portafilter with a solid wood handle, one double-shot filter basket, and one 51mm espresso puck screen.

  7. How do I clean and maintain the OpenShot Portafilter?
    Remove the filter basket and puck screen after brewing. Rinse the metal components with warm water and gently brush away coffee residue. Wipe the wooden handle with a damp cloth and dry thoroughly. Avoid soaking the wooden handle or placing it in the dishwasher.

  8. Does the OpenShot Portafilter come with a warranty?
    Yes. The CASABREWS OpenShot Portafilter comes with a 12-month limited warranty. For warranty details, care instructions, and additional support, visit our Support Center.
