The first already clarifies many things: «A glass of water should always be drunk before coffee”says Mauro Illiano, professional taster, founder of “Napoli Coffee Experience”, member of the board of experts of the Slow Food Coffee Coalition and, among other things, editor of the first guide to Italian coffees and roasters.
