Champion Instructor Shares Practical Expertise
Breaking Down the Keys to Espresso Extraction and Tasting

At the event, Zhang Zhonglun delivered an engaging two-hour session focused on the core extraction techniques and sensory evaluation system of Italian coffee, sharing professional knowledge and hands-on experience in depth. In the Italian Espresso extraction segment, he precisely explained key technical parameters including coffee dose, equipment hot-water temperature, extraction pressure, extraction time, and final beverage yield. These parameters, validated through practical experience, provided participants with actionable operating guidance.

He also explained sensory analysis through three dimensions - visual evaluation, aroma evaluation, and tasting techniques - and organized an on-site tasting exercise, helping participants deepen their understanding of coffee flavor through both theory and practice.

Flagship Product Showcase: Castle Captures Attention

A highlight of the event was Castle, Dr.coffee's high-performance fully automatic coffee machine developed specifically for specialty coffee businesses. It became one of the main attractions on site. With a neo-classical retro design that breaks away from the stereotypical look of traditional fully automatic machines, its soft, flowing lines blend naturally into specialty coffee shop interiors.

Its core configuration further demonstrates industry-leading strength:

The Super Milk Foam system uses an integrated heating component to produce hot or cold milk, hot or cold milk foam, and hot or cold milk topping at the touch of a button, with a full 0%-80% foaming range. The ultra-precision grinding system combines Swiss Ditting metal flat burrs with a BLDC brushless motor, using a minimum adjustment increment of 1/13 of a turn to achieve extremely high grinding precision and greatly improve extraction consistency. Brewing System 4.0 uses heat-conduction technology to maintain stable extraction water temperature, while its large 30 g coffee-powder capacity enhances both body and peak-hour output. In addition, the three-bean-hopper design supports flexible blending of multiple bean types and triple grinding efficiency, while the intelligent steam wand paired with a 3 L steam boiler ensures consistent customized milk foam - comprehensively meeting both quality and operational requirements in specialty coffee.

Interactive Experience Heats Up: Experiencing Real Product Strength Hands-On

During the interactive experience session, participants enthusiastically tried the Castle fully automatic coffee machine themselves. From bean grinding and milk foaming to precise extraction and flavor tasting, they directly experienced the machine's ability to reproduce the output quality of an experienced barista, while also recognizing its advantage in significantly reducing store labor and management costs. Many coffee shop owners commented on site that Castle's performance configuration and exterior design are highly suited to specialty coffee operations, offering a new way to improve both quality and efficiency in store management.

The Beijing stop of the Dr.coffee National Coffee Masterclass Series has now concluded successfully. Through professional guidance from a world-champion instructor and a strong showcase of the Castle coffee machine, the event injected new momentum into the specialty coffee industry. Looking ahead, Dr.coffee will continue to invest in product R&D and industry services, launch more high-quality coffee equipment and professional exchange activities, and work with industry partners to build a stronger future for specialty coffee.
