The Aeropress is dead simple: I haven’t found much of a difference, taste wise, when using 14 to 18.5 grams of beans. I usually stick with 18.5g at a relatively coarse grind size (65 on my DF64 if that means anything to you, it goes from 100 which is really coarse to 1 which is extremely fine, like for Turkish Coffee, well below espresso, which is usually in the 12-15 range), grind my beans fresh, and use boiling water since I largely drink medium or light roasts. I let it brew for 2.5 minutes and it’s damn good every time. I’ve even let it brew for like 7 minutes when I forgot to set a timer, thinking it was going to be disgusting swill and it was only a bit bolder than what I was used to. It’s pretty hard to mess up an Aeropress brew IMO.
