The Jura S8 and Jura Z10 are both premium machines with the same HP3 fine-foam system and outstanding build quality. The Z10 costs roughly $1,000 more. Here is what that money actually buys - and whether it is worth it.
The Grinder: The Most Important Difference
The single most meaningful difference between the S8 and Z10 is the grinder.
The S8 uses the Aroma G3 - Jura’s standard steel conical burr grinder, shared with the E8 and ENA 8. It is an excellent grinder that produces consistent, well-extracted espresso.
The Z10 uses the P.R.G. (Professional Rotary Grinder) - a different design that runs at lower RPM, generates less heat, and offers finer grind adjustment. In practice, the P.R.G. produces noticeably more aromatic espresso, better crema development, and greater sensitivity to adjustments. It is the same class of grinder found in commercial super-automatics.
For buyers with a developed espresso palate who will notice the difference in the cup, the P.R.G. alone justifies meaningful consideration. For buyers who primarily taste “strong or mild,” it will not matter.
Winner: Z10
Cold Brew
The Z10 includes a dedicated cold brew function. It produces coffee concentrate at low temperature without heat - a genuinely different drink from chilled hot espresso. You can make iced lattes, cold brew concentrate for mixing, and nitro-style cold coffee.
The S8 has no cold brew function at all. If cold coffee drinks are part of your routine, this is a hard Z10 advantage.
Winner: Z10 (clear advantage if cold brew matters to you)
Specialty Drink Count
| Machine | Specialties |
|---|---|
| S8 | 15 |
| Z10 | 32 |
The Z10’s 32 specialties include everything the S8 makes plus cold brew variations, cold foam options, and additional hot specialty drinks. The S8’s 15 is more than most households use regularly. For the average buyer, the extra drink count is a nice-to-have, not a deciding factor.
Winner: Z10 on variety, though it rarely matters in practice.
WiFi and App Control
The Z10 supports the J.O.E. (Jura Operating Experience) app over WiFi. You can program drink recipes, adjust settings, and monitor maintenance remotely. For tech-oriented buyers who want to control their machine from a phone, this is genuinely useful.
The S8 has Bluetooth connectivity via the J.O.E. app but relies on short-range Bluetooth rather than WiFi. WiFi-based control on the Z10 works reliably from anywhere on your home network.
Winner: Z10 for connectivity, though many buyers never use the app consistently.
Touchscreen and Interface
The S8 has a 4.3” touchscreen - the largest in the Jura lineup (except the GIGA series). Navigation is fast and responsive. The Z10’s display is similar in quality. For daily use, both machines are easy to operate. There is no meaningful difference in the daily experience of selecting and adjusting drinks.
Winner: Tie
Water Tank and Capacity
| Machine | Water Tank |
|---|---|
| S8 | 2.3L |
| Z10 | 2.4L |
Near-identical. The Z10’s 0.1L advantage is irrelevant in practice.
Winner: Tie
Price and Value
The S8 typically runs $2,000-$2,500. The Z10 runs $3,000-$3,500. The $1,000 premium buys the P.R.G. grinder, cold brew, 17 additional specialties, and WiFi connectivity.
For buyers who will use cold brew regularly and who have a palate that appreciates the P.R.G. grinder’s output, the Z10 is worth every dollar. For buyers who primarily make cappuccinos and lattes and will never use the cold brew function, the S8 delivers almost identical daily value.
Winner: S8 on value for most buyers. Winner: Z10 if cold brew and the P.R.G. grinder are important to you.

Which Should You Buy?
Choose the S8 if:
- Cold brew is not something you will use
- You cannot justify the $1,000 premium
- A 4.3” touchscreen and 15 specialties covers your household’s needs
- Espresso quality from the Aroma G3 satisfies your palate
Choose the Z10 if:
- Cold brew drinks are part of your regular routine
- You have a developed espresso palate and will notice the P.R.G. grinder’s output
- You want the complete flagship Jura experience
- WiFi app control is something you will actually use
For most buyers considering this comparison: the S8 is the more practical choice. The Z10 is the right machine for buyers who genuinely want cold brew and care about the P.R.G. grinder. If you are buying the Z10 primarily for the prestige of “the best Jura,” the S8 will satisfy you at $1,000 less.
