Looking to take your AeroPress® coffee brewer to the next level? The Prismo coffee brewer attachment is going to get you there. Unlock espresso-style coffee without lugging around a full-blown machine. Countless prototypes were created before Fellow landed on a final iteration that could create enough pressure for an espresso. The no-drip seal allows for full immersion brewing resulting in a syrupy, full-bodied one, two coffee punch. What’s the secret sauce? Pressure Actuated Valve “pulls a shot” with more pressure. The specialized valve seals until you press down, creating built-up intense pressure. No Drip Seal lets you ditch the flip. Brew a full immersion method without inverting your AeroPress®. Reusable Etched Metal Filter filters out the grit. The 70 micron etched fine metal filter stops sludge from creeping into your cup. PRO TIP: The Prismo attachment can also make a mean coffee concentrate.
