Just came back from 2 weeks in Italy and Sicily. During my stay, I had 2-3 espresso a day. Rome, Florence, Venice, Assisi, Pompeii, Palermo, Agrigento, Taormina, and Amalfi. All but two coffee bars use Kimbo Bar coffee beans, and all but one coffee bar (in Pompeii) use volumatic machines. The one in Pompeii uses spring lever, and it was the best espresso among all. No weighting, just one or two clicks from a dosing grinder. No tamping either. They use a plastic tamper attached to the grinder. Slightly press the portafilter against it. No portafilter cleaning either. I have seen many very wet pucks. Dump, reload, insert, and serve. Normal cost is €1. In toursty areas is €2-3. Coffee bars are everywhere and most of them sell pastries as well.
To my surprise, I couldn't find any coffee beans for sale in stores, supermarkets, and duty free. Only ground coffee is available. Some of the coffee bars offer Kimbo Bar in 1 kg bag. I came across the only coffee roaster I found in Palermo. They had about 5-7 different types of beans ( I bought 2-250g bags)
All of the espresso taste the same. Just one or two tasted off. Capp and latte sucks. They don't know how to froth milk - too hot with a lot of air.
