Thanks to Jasonian's advice to "throw the instructions away", I've started using the Aeropress at home again, using the inverted method. I found a bunch of recipes online, and some of them say to stop plunging down before you hear the "pffssssst" at the end.
Does anyone know the theory/philosophy behind this approach? What are the benefits, and how does this affect the taste of the coffee?
Perhaps I'll do a side-by-side taste test with "pfffsssstttt" versus "no pfffsssettttt" lol.
