Italy develops a wearable tasting helmet to objectively quantify the sensory emotions of coffee through physiological signals.

As the 2024 WBrC World Brewers Cup came to a close, curiosity was once again piqued about what judges feel inwardly when tasting coffee.

Comparison of Ice Addition Timing for Iced Hand-Brewed Coffee: An Analysis of Front Street's Japanese-Style Iced Hand-Brew Parameters and Sensory Differences

Should ice be added before or after brewing when making iced pour-over coffee? This question puzzles many coffee lovers. Front Street Coffee conducted a controlled experiment using 15 grams of Kaffa Forest coffee beans, a 1:10 coffee-to-water ratio, a water temperature of 90-91°C, and a grind setting of 9 on an EK43s grinder, testing two brewing sequences: ice added first and ice added last.

The root of the difference lies in how much ice melts. This article will present the complete experimental parameters, step-by-step procedure, and sensory comparison results to help readers understand how the timing of ice addition affects the flavor of iced pour-over coffee.

What Are the Internationally Recognized Barista Certifications? A Full Analysis of SCA Certification Levels and Their Practical Value

For those looking to enter the coffee industry, the first question many ask is: what exactly is an internationally recognized barista certification?

The Design Logic of the Coffee Flavor Wheel and Single-Origin Coffee Tasting Methods: Flavor Analysis from the Inner Ring to the Outer Ring

The coffee flavor wheel is an important tool in the specialty coffee tasting system. Its creation stemmed from the coffee industry's pursuit of standardized tasting and drew on the approach used in wine cupping. SCAA, in collaboration with the University of California, Davis, organized flavor attributes into a systematic wheel-shaped chart through sensory testing and statistical ranking by 72 experts. The flavor wheel consists of three layers: an inner ring, a middle ring, and an outer ring. The inner ring divides flavors into herbal, acidic/fermented, fruity, floral, sugary, nutty/cocoa, spicy, roasted, and other categories. Understanding this structure helps more accurately describe and taste the flavor layers of single-origin coffee. Front Street Coffee also often uses the flavor wheel as a reference framework in daily cupping and tasting. [more…]
