If you fancy 3rd wave Italian espresso not dark bulk roasted robusta then it’s worth tracking down Gardelli roasters who sell a lot outside of their home market in Italy but the big cities will have a few cafes that use it.
He was world roasting champion recently and all the coffees I have tried have been great, I was lucky enough to try some Wush-Wush from Columbia which is on par with Gesha from Panama and similar in price (£100/kg) but a much bigger body and mouthfeel, not as delicate as Gesha but I actually prefer it even though Gesha is supposed to be the best coffee available. (This was as a V60)
