Wendougee Data-S – High-End Dual boiler Espresso Machine with Pressure profiling

The brew boiler is a saturated group head (integrated with the group), meaning water and metal sit at the same temperature. This design virtually eliminates heat loss and ensures rock-solid brew temperature stability , yielding consistent flavor clarity shot after shot – especial noticeable with light roast beans.

From cold start to brew-ready in under 10 minutes. You can pull your first espresso shot before you’ve finished grinding, thanks to high-efficiency heating elements and the dual-boiler design. No more lengthy warm-ups on busy mornings.

Two independent stainless steel (304L Stainless steel) boilers (1.8 L steam boiler + 0.8 L brew boiler) Built to professional standards, the Wendougee Data-S features uncompromising construction quality. Beneath its sleek exterior, every critical component is metal. The saturated brew boiler merges directly with the group head, keeping the brewing temperature incredibly stable from the boiler to the coffee bed . Unlike many home machines with traditional group heads, this saturated group design means the brew water temperature stays within a tiny variance, so your first shot and last shot of the day are identical in taste.

Meanwhile, a dedicated steam boiler provides ample dry steam for creating silky microfoam, without ever robbing heat from the brew circuit. Thanks to the dual 2200 W heating elements and efficient design, the entire system reaches operating temperature in under five minutes – turning your weekday morning routine into a quick café-like experience. You can pull espresso and froth milk simultaneously, with no performance lag. As coffee industry experts note, a dual-boiler with saturated groups offers “independent thermal stability” for each function and allows brewing and steaming with zero compromise . In short, the Data-S’s engineering ensures temperature precision and speed that rival commercial espresso machines.

All-metal internal plumbing, an Italian-made flow meter, and commercial-grade solenoid valves ensure reliability and shot-to-shot consistency. The robust build quality mirrors commercial machines, translating to a longer lifespan and more consistent performance. Every pipe and connector is metal – no plastic to crack or impart off-tastes – for ultimate durability.

Fine-tune flavor like never before. The Data-S empowers you to sketch custom pressure or flow profiles for your espresso shots. Using the front-panel gauge or the app’s live readout, you can watch the pressure/flow line in real time as the machine follows your programmed curve. This level of control lets you experiment with extraction like a veteran barista: for example, start with a gentle low-pressure pre-infusion to bloom a light roast, then gradually ramp up to full pressure; or set a flat 3 mL/s flow rate for a “lever-style” steady extraction. The responsive gear pump and sensors ensure your programmed profile is hit accurately for every shot. The result is the ability to highlight different flavor notes and textures in your coffee by simply adjusting the pressure/flow recipe – an unthinkable capability on ordinary home machines. By mastering pressure profiling, you can unlock sweeter flavors, better balance, or more body from the same beans, all at the push of a button

The Commercial Grade Gear Pump in the Wendougee DATA S espresso machine is engineered for precision and durability, delivering café-quality performance in a home setting. Key attributes include:

• Precision Pressure Control: Utilizes real-time feedback to maintain consistent pressure during extraction, enabling accurate adherence to programmed profiles (e.g., pre-infusion, pressure ramps, or flow control).

• Commercial-Grade Build: Features all-metal construction and commercial components, ensuring longevity and resistance to wear under frequent use.

• Variable Pressure Support: Capable of up to 12 bars of pressure, exceeding standard 9-bar systems, and allowing nuanced customization for diverse coffee profiles.

• Quiet Operation: Designed for low noise, enhancing the user experience without noise.

• Smart Integration: Works with the Wendougee E-Bar app, enabling automated pressure adjustments

This pump bridges professional espresso standards with home usability, offering barista-level control over extractions 

Join a worldwide community of coffee enthusiasts with the Wendougee Data-S’s smart features. Using the Wendougee E-Bar App, you can control every variable of your espresso making from your smartphone or tablet.

This connected creativity means your machine is not limited to out-of-the-box settings; it continuously evolves. Over-the-air updates delivered via the app can add new brewing modes or improvements, keeping the Data-S up-to-date with the latest in coffee science. Essentially, the app integration turns your kitchen into a smart coffee lab (minus any technical hassle), where pushing the boundaries of espresso is as simple as tapping “brew” on your screen. Embrace modern espresso brewing with features usually found only on cutting-edge commercial machines.

Intuitive One-Press Controls – After dialing in the perfect shot parameters, save them as a recipe profile. Thereafter, brew with a single button press. The interface is beginner-friendly on the surface (one-touch simplicity), but offers pro-level control underneath for those who want to experiment. It’s confidence-inspiring for new users and empowering for experienced baristas who like to tinker.
