I'm not stupid, if you want to drink stewed coffee from a cafetiere that's your choice. Just don't pretend that you're some kind of coffee aficionado.
This statement is ignorant, snobbish idiocy
Cafetieres can - absolutely - be used to make great coffee. Putting
some beans through an espresso machine absolutely kills them, whilst others are absolute shite in a cafetiere.
Drip / filter machines - like cafetieres - bring out different qualities in beans. One is a slower diffusion of flavour, the other is - essentially - torturing beans to living buggery by wringing every last morsel of goodness out in a matter of seconds. Beans respond differently to each means of extraction.
Likewise, different means of extraction respond better to different levels of roast. Someone who puts a French / Viennese roast into a filter / cafetiere is asking for a cup of sewage-flavoured over-wrought carbonated bitter crap. Anyone who puts a light (or -

- cinnamon) roast into an espresso machine will get a crap shot with bugger all crema, if they get owt. There is - of course - a continuum of roasts in between, many of which'll work as a level of compromise in either. I'd rarely go as far as Viennese even for espresso.
I have beans (like an Ethiopian decaf Sidamo) that I would not touch in an espresso machine. Likewise a Columbian Huila Antioc. I mean - hey, go for it. But you'll get a gash, ashy, messed-up cup.
Similarly, there're others that I reallyreally wouldn't put in a cafetiere. Like Brazilian daterra decaf. Again - it produces a hollow, wrought, undrinkable cup. But is
excellent in espresso.
One of the key factors - IME -
tends to be the level of roast that the bean responds best to. But, then again, beans also seem to respond very differently to various extraction processes
per se n all.
In brief - your snobbishness towards Herby is unqualified balls. Likewise your attitude towards cafetieres. Which -
if used properly (I've always used 'em for 4 mins with water 4 seconds off the boil) can produce an excellent cup. Well, yes. Leave them to stew and you'll get a bitter mess. So don't leave them to stew. Duh.
