Bean-to-cup with a grinder Jura says is built to last the machine's life

Scores higher on value for money, kitchen fit & noise.

A household that wants hot, cold brew and light brew coffee drinks, 51 of them, from one touchscreen with no barista skill at all

Scores higher on drinks & milk system, grinder & grind control, ease of use.

• +A variable brewing unit that doses 5 to 16g, which is a wider range than most bean-to-cups admit to.
• +The Pulse Extraction Process, JURA's method for short drinks like espresso and ristretto.
• +A CLEARYL Smart+ filter with automatic detection, and an integrated rinsing, cleaning and descaling programme.
• +Wi-Fi to a home network and control from JURA's J.O.E. app.
• +Zero watt standby and a programmable switch-off.

• −No milk system at all, so no cappuccino, latte or flat white without a separate frother.
• −JURA publishes no price on its own site, and retailers list it at $1,399.
• −Warranty is two years or 6,000 brews, whichever comes first, so a busy household reaches the cap first.
• −No grind setting count is published, and the grinder's aroma claim carries a footnote mark with no footnote.

• +51 specialities, including Cold Brew versions of eleven drinks and Light Brew versions of eight, all at one touch.
• +The P.R.G.2+ grinder sets grind and dose for the drink you choose, fine for espresso and coarse for Cold Brew.
• +A 2.4 l water tank, 3 brew temperatures, 10 strength levels and a Caffeine Regulator with 3 levels.
• +A powder chute for ground coffee, One-Touch milk system cleaning and a CLEARYL Smart+ filter the machine detects automatically.
• +Aluminium front panels, a 4.3 inch touchscreen, Wi-Fi for the J.O.E. app and manufacture in Switzerland.

• −At $4,499.00 it is the most expensive bean-to-cup machine on this site, $1,900 more than the Jura E8.
• −Jura's page does not state the grinder's burr material.
• −The bean container holds 280 g, no more than the E8, so a busy household refills it often.
• −Jura still lists the first generation Z10 alongside this one, with 40 specialities, so check the NAB code before buying.
