The flavours of an espresso Want an espresso? But what does it taste like? Here I am to explain the mystery: the flavours of coffee are acidity and bitterness; the first flavour is characteristic of Arabica coffee, which has a quasi-acidity caused by
the richness of the coffee’s aromas. In contrast, bitterness is
characteristic of Robusta coffee, which has a high caffeine content
that gives it a chocolatey flavour that lingers on after each sip. In order to get
the maximum “good” acidity out of an espresso, I recommend Slow Food’s Harenna Forest Wild
Coffee, prepared using a De’Longhi Autentica, on the double espresso setting
and with grade 4 grinding.
