Loving your AeroPress but wanting to get a little bit more out of it? Introducing Prismo. Brought to you by the innovative folks at Fellow, the Prismo is a pressure actuated valve made specifically for the AeroPress to create espresso-style coffee. This attachment allows a significant amount of pressure to build up, creating a long-lasting crema and a thick, full-bodied shot. No need to worry about grinds in your cup or wasting paper filters -- the Prismo comes with a reusable 70-micron etched filter. 

And while this simple attachment might not replace the fancy machine on your countertop (there is no way to replicate by hand the heat and pressure that a machine uses), it's an inexpensive way to get pretty close. Simply lock, load and press.
