Coffee and Caffeine FAQ

"Whether good quality robusta improves the flavor of espresso is up for debate but in all likelihood this is a debate that will linger for quite some time."

Yes; as stated elsewhere on this site, robusta beans have qualities that differ from arabica beans. They produce a tighter crema and have more strength and smoke in taste compared to arabica. That is why they are part of many great espresso blends.

In southern Italy, around Naples, you'll see blends that contain up till 40% robusta and still, probably much thanks to the pro baristas, they taste better than the average "100% arabica true-italian-pro-coffee" you find in your average supermarket.

In my opinion, what's most important when it comes to brewing great coffee is using the best brewing technique available today, which is espresso style.
Fast extraction times is a good way to keep bad taste out of your cup. And it's a friend of your stomach too, believe me!
