Jura J8 Twin Automatic Coffee Machine
The Jura J8 Twin delivers a singular capability: dual P.A.G.3+ high-performance conical grinders processing two different coffee blends, combining two coffee machines in one compact device. Regular and decaffeinated simultaneously available, dark espresso roast paired with mild lungo blend, single-origin Ethiopian alongside everyday Colombian - the dual grinder configuration opens entirely new possibilities for coffee pleasure. Whether preferring caffeinated morning coffee and decaf evenings, or sampling multiple roasts throughout the day, the J8 Twin makes it happen without hopper swapping or bean mixing.
Both P.A.G.3+ grinders feature integrated aroma control actively monitoring grind consistency, delivering precise grinding results regardless of bean variety. Between preparations, the grinders remain in intelligent rest mode - gentler on mechanisms, maximising service life whilst ensuring consistently delectable flavour. This represents the third generation of Jura's Professional Aroma Grinder technology, refined through years of development for optimal performance and longevity. Each grinder operates independently with separate adjustment, enabling different coarseness settings for different beans if desired.
The comprehensive feature set includes Sweet Foam function flavouring milk foam during preparation for subtle sweetness, Coffee Eye intelligent sensor ensuring cups are positioned under correct spouts for selected specialities, and the Panorama Coffee Panel providing intuitive gateway to 31 specialities. Easy Mode with sliders enables maximum flexibility adapting drinks to chosen cup sizes. Assistance systems, aroma control recommendations, and One-Touch cleaning make operation straightforward despite the sophisticated dual-grinder engineering. The 1.9-litre water tank and dual 280g hoppers support 20-50 cups daily whilst clean lines, high-quality materials, and superior craftsmanship create elegant sophistication.

What Customers Ask About Jura J8 Twin
How do I choose which grinder the machine uses for each drink?
The Panorama Coffee Panel enables selecting which grinder to use when preparing drinks. You programme preferences - perhaps grinder 1 for espresso using your dark roast, grinder 2 for americano using mild beans. The machine remembers these assignments. For flexibility, you can override defaults and manually select grinders for individual drinks. This intelligent assignment means the machine automatically uses the appropriate beans for each speciality based on your preferences, whilst retaining manual control when desired.
Can both grinders operate simultaneously for faster drinks?
No, the grinders operate sequentially rather than simultaneously. Drinks are prepared individually using one grinder at a time. However, the dual configuration means you can immediately prepare a second drink using different beans without delay - if one person wants regular coffee whilst another wants decaf, both drinks happen quickly in succession using their respective grinders. The advantage isn't simultaneous operation but rather instant access to two bean varieties without hopper management.
What's the practical advantage of P.A.G.3+ versus P.A.G.2+?
The P.A.G.3+ represents third-generation Professional Aroma Grinder technology with refinements in aroma control accuracy, rest mode efficiency, and longevity engineering. Jura's grinder technology evolves through generations - P.A.G.3+ incorporates learnings from P.A.G.2+ deployment with enhanced monitoring capabilities and extended service life characteristics. For users, this translates to more consistent grinding over longer periods and better preservation of bean aromatics through improved rest mode management. The engineering sophistication matters particularly with dual grinders where maintenance of both systems is crucial.
Do I need to maintain two separate grinders?
Yes, both grinders require maintenance following machine prompts. However, Jura's engineering minimises complexity - the machine guides you through maintenance for each grinder using the same procedures and cleaning products. The intelligent rest mode reduces wear on both grinders, whilst aroma control monitoring helps identify when cleaning is needed. Whilst dual grinders technically double maintenance points, the simplified procedures and automated guidance prevent this becoming burdensome. Using quality beans in both hoppers and following prompted maintenance schedules ensures reliable performance from both systems.
How does this compare to the GIGA 10's dual grinders?
The J8 Twin at £2,100 offers dual P.A.G.3+ conical grinders, 31 drinks with Sweet Foam and Coffee Eye, 20-50 cup capacity, and Panorama Panel. The GIGA 10 at £3,795 provides dual ceramic disc grinders, 35 drinks with Cold Extraction and parallel preparation, 50-150 cup capacity, and 6.7-inch Panorama touchscreen. Choose the J8 Twin if you want dual grinders for bean variety with Sweet Foam at £1,695 savings and moderate capacity suits your needs. Choose the GIGA 10 if you need significantly higher capacity, cold brew capability, or parallel milk preparation. Both offer dual grinders but serve different usage intensities.
What We've Learned About Dual Grinder Machines Since 1972
In our 52 years helping customers select coffee equipment, we've observed that dual grinder configurations serve specific usage patterns exceptionally well. The most common scenario: households where some members need decaffeinated coffee whilst others want regular. The J8 Twin eliminates the inconvenience of maintaining separate machines or constantly swapping beans in a single hopper. Having both types instantly available transforms daily usage for these households.
Coffee enthusiasts who explore different bean varieties particularly value dual grinders. Perhaps you've found an exceptional Ethiopian single-origin you want to savour as espresso, whilst maintaining reliable Colombian beans for everyday coffee. The J8 Twin enables experimenting with speciality beans without surrendering your everyday reliability. This flexibility encourages exploration - you're not committed to finishing an entire hopper of experimental beans before returning to familiar favourites.
The P.A.G.3+ grinders' aroma control and intelligent rest mode matter enormously for dual-grinder longevity. When you're maintaining two grinding systems rather than one, the engineering that extends service life and reduces wear becomes proportionally more valuable. Jura's focus on rest mode efficiency and monitoring means both grinders maintain consistent performance over extended periods. This reliability justifies the dual-grinder investment - the systems remain dependable rather than becoming maintenance burdens.
The 20-50 cups daily capacity suits households with 4-6 regular coffee drinkers who value bean variety, or couples who entertain frequently and want to serve diverse preferences. The capacity provides headroom for occasional high-volume days whilst the dual grinders ensure everyone's preferences are accommodated. This combination - substantial capacity with ultimate bean flexibility - makes the J8 Twin particularly relevant for households where coffee appreciation varies across members.
Specifications
Care & Use Instructions
Before first use: Remove all packaging and protective films. Rinse the 1.9-litre water tank and fill with fresh cold water. Fill both 280g bean hoppers with fresh coffee beans - this is your opportunity to establish your dual-bean strategy (regular/decaf, different roasts, everyday/special, etc.). If using Sweet Foam, fill the syrup attachment with compatible syrup. The machine will guide you through initial setup including system priming, both grinder configurations, and Coffee Eye sensor calibration. Follow the Panorama Coffee Panel instructions during first-time setup.
Establishing your dual-grinder strategy: Decide how to use the two grinders: regular and decaffeinated beans, dark roast and light roast, single-origin and blend, or any combination matching your household's preferences. Label the hoppers clearly if helpful. Configure each grinder's coarseness settings independently based on the bean characteristics. The Panorama Panel enables programming which grinder to use for each drink type, or you can manually select for individual drinks. This strategic planning maximises the dual-grinder advantage.
P.A.G.3+ grinder operation: Both third-generation grinders feature aroma control actively monitoring grind consistency. The machine may recommend grind settings for different specialities based on aroma control data. The intelligent rest mode activates automatically between preparations on both grinders, reducing wear and extending service life. This automated management means the sophisticated dual-grinder system operates reliably without constant manual intervention. Simply use quality beans and follow maintenance prompts.
Daily use with Panorama Coffee Panel: Navigate the 31 drink options using the intuitive 3-screen interface. Select your drink, and the system automatically uses the programmed grinder (or manually override if desired). Easy Mode sliders enable adapting drink parameters to your cup size. The Coffee Eye sensor detects cup position and guides correct spout placement. The combination of Panorama Panel, Coffee Eye, and aroma control creates remarkably intuitive operation despite the engineering complexity.
Sweet Foam function: Fill the syrup attachment with compatible syrup (check Jura specifications). Select Sweet versions of drinks for automated syrup incorporation during milk frothing. The Sweet Foam function works identically to single-grinder J-line models - the dual grinders don't affect milk system operation. Clean the syrup attachment regularly to prevent buildup that could affect dosing accuracy.
Coffee Eye sensor with dual grinders: The intelligent cup sensor guides positioning regardless of which grinder you're using. When preparing drinks using either grinder, the Coffee Eye ensures correct spout placement for the selected speciality. This assistance becomes particularly valuable when serving guests who might not understand the dual-grinder configuration - they simply position their cup and the machine guides them correctly.
Maintaining dual grinders: Both P.A.G.3+ grinders require maintenance following machine prompts. The Panorama Panel guides you through cleaning procedures for each grinder separately using the same methods and products. The intelligent rest mode and aroma control help minimise wear on both systems. Use quality beans in both hoppers - oily, caramelised, or flavoured beans should be avoided in either grinder. Regular maintenance of both systems ensures consistent performance and justifies the dual-grinder investment.
One-Touch milk system cleaning: After preparing milk drinks, activate the automated cleaning cycle through the Panorama Panel. The HP3 system flushes automatically, completing maintenance in moments. Remove milk carafe and store in refrigerator between uses. Perform thorough deep cleaning at regular intervals following machine prompts. The milk system maintenance is identical to single-grinder models - the dual grinders add complexity only to coffee preparation, not milk handling.
J.O.E. app features: The J8 Twin includes built-in WiFi connectivity (no separate adapter required). Download the J.O.E. app for smartphone control, programming which grinder to use for each drink, creating personalised profiles, and tracking maintenance schedules for both grinders. The app becomes particularly useful with dual grinders - manage complex grinder assignments and preferences through the intuitive smartphone interface rather than repeatedly configuring through the machine.
Automatic maintenance programmes: The J8 Twin prompts you when cleaning or descaling is required through clear Panorama Panel displays. Follow the on-screen instructions guiding you through each maintenance process including grinder-specific procedures. Use Jura-approved cleaning tablets and descaling solution to protect both sophisticated P.A.G.3+ grinders and other components.
What to avoid: Don't use non-compatible syrups in the Sweet Foam attachment. Don't use oily, caramelised, or flavoured beans in either hopper. Don't ignore maintenance prompts - with dual grinders, proper maintenance becomes proportionally more important. Don't use non-Jura cleaning products. Don't leave milk or syrup in systems between uses. Don't mix beans within a single hopper - keep each hopper dedicated to one bean type for optimal results.

WiFi connectivity is built-in (no separate adapter required). You'll need to purchase coffee beans for both hoppers, compatible syrup for Sweet Foam function, and we recommend Jura cleaning tablets and descaling solution for maintenance. The Claris water filter is typically sold separately. Contact us to confirm what's included with current stock.
What's the most common way customers use the dual grinders?
The most common configuration is regular and decaffeinated beans - enabling caffeinated coffee during the day and decaf in the evening without hopper swapping. The second most common is dark roast for espresso paired with lighter roast for longer drinks. Coffee enthusiasts often use one hopper for reliable everyday beans whilst experimenting with single-origin speciality beans in the other. The beauty of dual grinders is flexibility - use them however matches your household's consumption patterns.
Can I use the same beans in both hoppers for higher capacity?
Yes, though this somewhat defeats the dual-grinder purpose. If you simply want larger bean capacity, filling both hoppers with identical beans provides 560g total capacity versus 280g in single-hopper machines. However, at this usage level, you're paying for dual-grinder engineering without utilizing the bean variety capability. If your primary need is capacity rather than variety, consider whether single-hopper models with larger hoppers or higher daily capacity ratings would better serve your needs at lower cost.
How does this compare to the J10?
The J8 Twin at £2,100 offers dual P.A.G.3+ grinders, 31 drinks with Sweet Foam and Coffee Eye, 20-50 cup capacity, and Panorama Panel. The J10 at £1,795 provides single P.A.G.2+ grinder with Cold Extraction Process, 42 drinks including cold brew, Sweet Foam and Coffee Eye, and 4.3-inch touchscreen. Choose the J8 Twin if dual grinders for bean variety is your priority and you don't need cold brew. Choose the J10 if you want cold brew capability and broader drink selection with single grinder suffices. The £305 premium buys you the second grinder and Panorama Panel.
Do both grinders need the same grind settings?
No, each grinder adjusts independently. This enables setting coarser grind for your light roast beans and finer grind for dark roast if desired, or matching grind settings to each bean variety's optimal extraction. The independent adjustment represents one advantage of dual grinders - optimize each system for its specific beans rather than compromising with universal settings. The aroma control on each grinder helps recommend appropriate settings based on the beans you're using.
Is this suitable for office use?
The J8 Twin's 20-50 cups daily capacity suits small offices (5-10 people) where bean variety matters - perhaps some staff want decaf whilst others prefer regular, or the office wants to offer both everyday coffee and premium single-origin options. The Coffee Eye sensor helps multiple users operate correctly. However, ensure someone is designated for maintaining both grinders, milk system, and Sweet Foam attachment. The dual grinders add value in offices with genuinely diverse preferences, but add maintenance complexity versus single-grinder models.
What if one grinder breaks - can I still use the machine?
If one grinder fails, you can continue using the functional grinder whilst arranging repair for the non-functional one. The machine doesn't require both grinders operational to prepare drinks - it simply becomes a single-grinder machine temporarily. However, grinder failure should prompt immediate contact with Jura service to restore full dual-grinder capability. Proper maintenance of both grinders following machine prompts significantly reduces failure risk - the P.A.G.3+ engineering with intelligent rest mode is designed for extended reliable service.
How does Jura warranty work?
Jura machines come with manufacturer warranty (typically 2 years for home use - confirm details at time of purchase). This covers manufacturing defects and component failures under normal use, including both grinders. Our Half-Price Replacement guarantee provides additional protection beyond manufacturer warranty. Register your machine with Jura after purchase to activate warranty coverage. With dual grinders, maintaining detailed records of maintenance performed on both systems becomes particularly important for warranty purposes.
