Insights from a World Championship Medalist
Decoding the Core Logic of Cross-Category Creation

In the sharing session, world championship bronze medalist Lin Dongyuan delivered a two-hour professional class themed 'Integrating Espresso Dial-In into Coffee-Spirit Creation.' As the global specialty coffee market continues to deepen, coffee cocktails have become an important bridge between coffee culture and the art of spirits. They are not merely beverages, but a threefold integration of experience design, technical expression, and flavor storytelling. Lin systematically explained a 'three-dimensional value framework' for coffee-spirit creation: the experience dimension should build distinctive sensory memories; the technical dimension should achieve precise control over extraction and mixing; and the storytelling dimension should incorporate origin culture and process narratives, giving each beverage both flavor and meaning.

During the hands-on segment, Lin focused on the key parameters of Espresso dial-in and the logic of flavor transformation, breaking down Espresso's flavor structure into acidity, sweetness, bitterness, and body. Through live demonstrations, he also explained extraction approaches for beans at different roast levels. Participants tasted in groups and directly experienced how parameter adjustments influence flavor, gaining practical insights from the exercise.

Castle Takes Center Stage
A Powerful Platform for Cross-Category Creativity

The Dr.coffee Castle fully automatic coffee machine became a focal point thanks to its strong performance in cross-category beverage creation. Designed specifically for specialty coffee settings, the machine breaks with conventional perceptions of fully automatic equipment through a refined neo-classical retro look. Its smooth, clean lines integrate easily into coffee shops, cocktail bars, and other diverse interiors. More importantly, its core configuration is precisely matched to the needs of coffee creation:

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 micron-level grinding precision and stable flavor from batch to batch. A large 30 g brewing capacity paired with a 3 L steam boiler enhances coffee body while efficiently handling peak demand. The Super Milk Foam system supports a 0%-80% foaming ratio and can produce hot or cold milk foam and milk topping at the touch of a button, adding rich layers to signature drinks.

Using Castle's three-bean-hopper design, Lin quickly switched between two coffee beans to extract different flavor bases. The machine's stable performance and ease of operation earned applause from the audience. Many participants noted that its precise temperature control and high efficiency address the common problems of inconsistent flavor and slow output in traditional manual workflows, providing reliable support for stores expanding into cross-category beverages.
