but about not messing the flavor of the coffee.
This is an important point of coffee. Coffee in the mix is fine, but the coffee flavor of the coffee beans must still be felt. The issue of mixing coffee is about the creativity of the coffee maker, but the real coffee maker will definitely not leave coffee there.
Coffee should taste like coffee, so mixes is good as long as they dont obscure the flavor of the coffee :), glad to see you around hive, thanks for the comment :)
