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.

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…]

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…]

Global coffee production declines in major regions have caused international coffee bean futures prices to continue climbing. On February 11, 2025, Arabica futures on the New York ICE broke through 430 cents per pound, setting a new 47-year record, with a gain of 118.57% over the past year. Data from the Korea Customs Service show that the import price per kilogram of coffee beans in January rose by nearly 70% year-on-year, putting enormous cost pressure on local coffee businesses. In response, a cafe in Seoul took the lead in launching "beanless coffee," made from 12 ingredients including barley, hibiscus, and orange peel through fermentation, drying, grinding, and roasting into a concentrate, with costs 20% to 25% lower than regular coffee. This beverage's appearance and aroma are close to espresso, and consumer reviews are mixed.
