To enable the filter and coffee machine to communicate, JURA uses modern RFID technology. Any machine fitted with the intelligent water system (I.W.S.®) recognises when a filter is inserted, automatically switches to filter mode and starts the rinsing process. When the filter capacity is nearly used up the machine prompts the user to change the filter. If the filter is not changed, the machine activates descaling mode. After a certain amount of use, the user is prompted to descale the machine. This can only be done when the filter is removed, so there is no more risk of user error resulting from misunderstandings.
As with all other blade grinders, transferring grinds to a machine or another container is a messy process. Its grind uniformity cannot compete with a burr mill of comparative price. While adequate for finer grinds, the Capresso 503.05 still underperforms for French press and cold brew. Furthermore, as with all other blade grinders on the market, this one suffers from a buildup of coffee dust. With a tiny bit more money, you can get a much more versatile machine like the 559 (#4 in this list) or 560 Capresso burr grinder (#2).
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!
