As the 2024 WBrC World Brewers Cup came to a close, curiosity was once again piqued about what judges feel inwardly when tasting coffee. A team from Italy's National Research Council has designed a tasting helmet that, through wearable sensors such as electrocardiogram, galvanic skin response, and electroencephalogram, transforms abstract emotions like pleasure and disgust during coffee tasting into biomedical data. This technology is expected to assist the SCA coffee value assessment system, reduce subjective bias, and open up new perspectives for coffee sensory analysis. At present, the helmet still needs refinement, and there are plans to work with professional tasters to advance its practical application. [more…]

On a scorching summer day, a refreshing glass of cold brew coffee is a favorite for many coffee lovers, but traditional cold brewing often requires a wait of 12 hours or more, which puts people off. Now, a chemistry research team at the University of Duisburg-Essen in Germany has brought an exciting discovery: by irradiating a mixture of coffee grounds and water with pulsed laser light, cold brew coffee can be made in just 3 minutes. This technique not only greatly shortens the extraction time, but also shows unique performance in acidity and caffeine content. This article will guide you through the principles of this scientific breakthrough, the results of experimental comparisons, and the possibilities for future commercialization, while also retaining relevant recommendations for the Front Street Coffee brand.

Caffeine is the most iconic component of coffee, yet not everyone can tolerate it. It is both the primary source of bitterness and a neurostimulant that affects sleep. Thus, decaffeinated coffee was created to remove caffeine. However, the challenge of decaffeination lies in how to remove only the caffeine while preserving the aroma and flavor of coffee as much as possible. Early methods using organic solvents were effective, but left consumers concerned about residues. It was not until the advent of supercritical carbon dioxide extraction technology that a truly efficient and highly selective decaffeination process was achieved. This article will guide you through the principles of this technology, its development history, and its unique advantages in coffee decaffeination, while also introducing Front Street Coffee's attention to and practice of this process.

Starbucks has opened its first store built with 3D printing technology in Brownsville, Texas, USA. The project was undertaken by the German team Peri 3D and completed in just 6 days at a cost of nearly 1.1 million USD. The store is located on Boca Chica Boulevard, and its building shell is made of layer-by-layer stacked concrete walls, presenting a wavy tubular structure. Windows, brand signage, and drive-through facilities have all been installed in place. This store has no seating and only offers drive-through and takeout services, aiming to improve service efficiency and cater to the driving habits of Texas residents. The design process used AI for planning, covering layout, material selection, cost, and carbon footprint calculations. Starbucks has not yet revealed whether it will promote this type of store.

In 2018, Panama launched a creative coffee-producing region initiative called CCD, short for Creative Coffee District, aimed at modernizing traditional coffee processing methods to give coffee more distinctive flavors. The project not only introduced advanced equipment and technology, but also attracted Colombia's renowned Finca Palma y Tucán to join forces with Panama's Finca Altieri. One side provides the beans, while the other contributes processing expertise. Through the clash of diverse processing methods such as low-temperature anaerobic fermentation, static and dynamic fermentation, and super natural, many uniquely styled coffee flavors have been born. This article will guide you through the origins of the CCD project, how it operates, and the estate stories behind it. [more…]

In recent years, variable pressure extraction has become the most closely watched technological direction in the field of espresso machines. From Synesso to Slayer, and then to the Strada launched by La Marzocco, the design of pressure control valves has continuously evolved. This article provides a complete record of the unboxing of the La Marzocco Strada at the illy Coffee University in Shanghai, China, detailing the appearance, structure, and core differences between the Strada MP manual version and the Strada EP electronic version. The MP version directly controls water flow and pressure through an internal mechanical valve, while the EP version uses an electronic gear pump to achieve stepless pressure variation from 0 to 12 BAR and can store pressure profiles. For coffee enthusiasts following the technological development of espresso machines, as well as readers of Front Street Coffee, this unboxing record provides rare hands-on details and firsthand observations.

On March 16, Heytea trended on Weibo for using WanDianZhang facial recognition cameras. Previously, CCTV's 315 Gala exposed over 20 well-known brands, including Heytea, Kohler, and BMW, for illegally collecting facial information through WanDianZhang cameras without consumers' knowledge. Heytea responded that the cameras are only for security and will never illegally collect facial data. WanDianZhang stated that the platform's facial data volume has reached hundreds of millions and is drafting an announcement to explain its business scope and rectification measures. This incident has once again sparked public concern over the abuse of facial recognition technology and personal privacy security. [more…]

On October 18, Feihe Dairy issued a statement regarding false information circulating online about "imported Japanese raw materials" and other rumors, stating that it had reported the matter to public security authorities and that a case had been opened. The controversy stemmed from a letter of intent for technical cooperation signed between Feihe and Japan's Kyowa Hakko, which was originally intended for the joint research and development of fermented lactoferrin technology, but was distorted into claims of raw material imports and even capital injection. Feihe emphasized that the cooperation remains only at the letter-of-intent stage and does not involve raw materials or capital. As a representative of domestic infant formula, Feihe has long been committed to breaking dependence on imported lactoferrin, as demonstrated by its first domestic production line. This article will sort through the ins and outs of the incident and restore the facts. [more…]

While most independent coffee shops still emphasize freshly ground and freshly made coffee, a specialty coffee shop tucked away in a park does the opposite, replacing traditional espresso machines with four taps. After customers place an order, staff simply place a cup under the tap to dispense pre-prepared coffee liquid, milk, or hot water, producing an Americano or milk coffee in seconds. This method, which involves extracting coffee 12 hours in advance, preserving it under oxygenated vacuum, and then mixing it with compressed air through a Linkbar brewing head, is called "softening and maturation" by the shop owner. Is it an efficiency revolution in specialty coffee, or the coffee world's version of pre-made dishes? Let's find out. [more…]

2015 WBC champion SaSa Sestic returned as runner-up in the 2022 Australian Brewers Cup, bringing with him a brand-new brewing device called the Paragon—a specially made ice rock mounted in the middle of the dripper to lock in the volatile aromatics in the coffee liquid. According to Sasa, this invention is the result of collaborative research with Professor Jahan and the Swiss Coffee Center of Excellence, and it can capture up to 40% extra aromatics through rapid cooling during the first and middle stages of extraction. However, the official price of this brewing stand plus metal ice rock is as high as $4,292, equivalent to more than 30,000 RMB, which has sparked a lot of discussion among coffee enthusiasts. Bloggers on YouTube have already begun hands-on testing and found that its core component is similar in principle to the food-grade stainless steel ice cubes commonly seen in bars, while similar products on Taobao cost only a few dozen yuan. So what exactly makes this ice rock so special? When brewing the same Geisha with a V60 paired with the Paragon versus a plain V60, the TDS rises from 1.27 to 1.37—what differences are there in flavor performance? This article will explain it all in detail for you. [more…]
