Jura J10 Twin Automatic Espresso Machine (Diamond Onyx)

The Jura J10 twin answers the question every serious coffee household eventually runs into: whose beans go in the hopper. Two separate 180 g bean containers feed two P.A.G.3+ grinders, so a decaf and a house espresso — or a dark roast and a light single origin — live in the machine at the same time and are ground at their own settings. In Diamond Onyx, with a 6.7" Panorama Coffee Panel spanning the front, it is the most finished-looking machine in the J line.

Two grinders, no compromise setting

On a single-grinder machine every bean shares one grind and one purge. The J10 twin keeps each side independent, with active grind-level monitoring on both and a rest mode between preparations. Going from a flat white on the morning blend to a decaf espresso after dinner is a tap, not a hopper swap.

Cold Brew, properly extracted

The Cold Extraction Process pulses cold water through the freshly ground bed in slow cycles rather than chilling a hot shot. You get the low-acid sweetness of an overnight steep in about a minute — and because the grinders adjust for it, cold specialities are ground coarser than the espresso ones instead of sharing one setting.

Key features

• 46 individually programmed specialities across Hot Brew, Light Brew, Cold Brew and Sweet Foam.
• 2 × P.A.G.3+ grinders with active grind-level monitoring and rest mode between preparations.
• 2 × 180 g bean containers — two coffees loaded at once, each with its own grind.
• 6.7" Panorama Coffee Panel touch display.
• HP3 milk system with interchangeable CX3 spout, height-adjustable from 4.2" to 6" for espresso cups through to tall glasses.
• Sweet Foam function — the syrup attachment is included in the box.
• Pulse Extraction Process (P.E.P.®) with a 5–16 g variable brewing unit and 8 coffee strength levels.
• Wi-Fi Connect included — J.O.E.® app control out of the box rather than as a paid add-on.
• Intelligent Water System (I.W.S.®) with CLARIS Smart+ filter recognition.

Who it’s for

Households where two people want genuinely different coffee, or anyone who keeps a decaf alongside a regular and is tired of swapping hoppers. It's also the J-line machine to choose if cold coffee is a year-round habit rather than a summer one.
