Reminds me of how (many) Italians like their coffee. The local bar proprietors were a bit surprised when I asked for the coffee without sugar .. a small cup of very strong and exquisitely delicious beverage! Quizzical looks changed to more surprised ones as I savoured every drop followed with a couple more for good measure. I think they were expecting me to gastronomically purge it or something ..
I had tried the sickly-sweet version but much prefer it without any sugar (or milk or cream, for that matter, not that I saw that being served in Italy although I think it was on the menus). IMHO why ruin a great coffee? .. but tastes of course vary. Even half-decent instant coffee gets ladled into the mug & the only additive is hot water ..
