Frequently Asked Questions

Is the J8 Twin better than the J8? ▼
It depends on your priorities. The Jura J8 Twin excels for users who want dual grinders to switch instantly between caf and decaf, while the Jura J8 is the better choice if you prioritize the Sweet Foam function to infuse milk foam with any syrup flavor.
How do the grinders compare? ▼
The J8 Twin uses a 2x Steel Conical, whereas the J8 features a Steel Conical (P.A.G.2+). While both are high-quality internal systems, they are sealed components. To prevent clogging and avoid expensive repairs, we strongly recommend using non-oily, medium-roast beans in both machines.
Which machine is easier to clean? ▼
Both the Jura J8 Twin and Jura J8 utilize a fixed brew group architecture. You cannot manually remove them to wash them. Instead, you must strictly use automated cleaning tablets when the machine prompts you, and avoid oily beans to prevent internal mold buildup.
Which machine costs more to maintain? ▼
Both machines have highly similar long-term ownership costs. We project an estimated annual maintenance cost of $350 for both the Jura and the Jura, which includes replacing water filters, descaling fluids, and cleaning tablets on the manufacturer's schedule.
Which machine handles oily coffee beans better? ▼
Neither machine handles oily beans well. Both the Jura J8 Twin and Jura J8 have highly sensitive grinders. Using dark, oily roasts in either of these machines will quickly lead to clogged hoppers, seized brew groups, and expensive repairs. Stick to dry, medium roasts.
