The Impressa Z6 employs Jura’s innovative Pulse Extraction Process brewing system. As opposed to a constant flow, water is instead pulsed through the grounds in short intervals that extract greater intensity and aroma while shortening the overall brew time. With P.E.P., espresso and ristretto can be prepared with greater clarity and flavor than ever before.
The Achilles heel of any super automatic, brewing times are, in my opinion, far too short for proper extraction of the good stuff from ground coffee. Part of the problem is the puck diameter - 46ml in the Jura Capresso S9. The other problem (and I blame the Swiss for this and their gosh darn love for caffe suise), is that the grinder can't be dialed fine enough.
If you’re a froth fan, you won’t be disappointed – Jura machines tend to be very good frothers (if that’s a word) and manage to top off drinks to the same standard as you’ll usually find in the high street coffee shops. It’s certainly an impressive result, even if we found it was a novelty the wore off rather quickly. We’re not the biggest advocates of milk foaming though, so you might be more excited that we are!
