You clean it?! That's where most of the flavor comes from! Like a perpetual stew.

Yes, coffee equipment is best rinsed. Mokka pots even explicitly instruct you not to use soap and let the residues build to mask any potential flavor from the metal.

I think that's specifically for aluminum moka pots. If you've got a stainless steel model, you can wash it properly without fear iirc.

Meanwhile, I'm seeing ads from Nespresso with catchphrases such as “Did you know aluminum makes your coffee even tastier?”.
