- stu2b50 4y agoKinda, it helps that you can do a proper pre-infusion phase, but in the end the bottleneck is human - there's no way you can get anywhere close to espresso pressure (not just 9 bars, anywhere near 9 bars) with your arm. You need mechanical advantage at least. The Prismo doesn't really increase the pressure in the chamber you can have by that much.

Not just human either, the aeropress' plastic isn't built to withstand high pressures and it's going to buckle, to say nothing of whatever you put the press on. Hoffman measured the prismo at 1.3 bars after adding a paper filter to the metal filter.
