Laser Pulse Technology Boosts Cold Brew Coffee: A New Scientific Breakthrough Achieving Extraction in Three Minutes
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.

Kangshifu Iced Black Tea Fan Meetup Sparks Discrimination Controversy: Fans Outraged Over Discriminatory Security Screening
A star's offline fan meet-and-greet that should have been full of joy sparked a wave of complaints due to discriminatory treatment during security checks. After the Qingdao fan meeting of Wang Yibo, spokesperson for Master Kong Iced Tea, many consumers reported through the Black Cat complaint platform that on-site security guards only confiscated support items from a specific fan group, forced body searches, and even shone laser pointers into their eyes, while fans with green support items, who were also consumers, enjoyed different treatment. The brand has not yet responded, and the incident continues to ferment on social media, with various accounts differing. [more…]
Nestlé and Master Kong enter the fray one after another—can label-free bottled beverages become a new trend in low-carbon packaging?
In recent years, as environmental awareness has risen, label-free bottled beverages have moved from once being considered "alternative" to becoming legalized. Brands such as Nestlé Japan Coffee, Asahi, Suntory, and Evian have successively tested the waters, and domestically, Master Kong has also launched label-free iced tea. Such products are mostly sold by the case, with only the shelf life and product name laser-printed on the bottle, while legal information is printed on the outer box. About 60% of Japanese consumers are willing to pay for them, mainly because it reduces PVC waste and the hassle of sorting. Domestic reactions are mixed: supporters believe it responds to carbon reduction, while those concerned see it as a promotional gimmick. This article sorts out the origins and development of this packaging change and explores whether it can be implemented over the long term. For friends who love drinking coffee, Front Street Coffee also continuously pays attention to such environmental trends. [more…]

Meteor Pour-Over Method Explained: Hand-Brew Techniques and Parameters for Dark-Roasted, Intense, Bitter Coffee Beans
Deep-roasted coffee beans, due to their fluffy texture and strong water absorption, release a large amount of gas when they come into contact with water in their fresh state, which provides the conditions for a unique brewing method—meteor pour. This article provides a detailed introduction to the principles and operational steps of this pour-over technique, including key parameters such as grind size, water temperature, and coffee-to-water ratio, as well as the pouring details of the three stages: blooming, point pouring, and outward spiral. Front Street Coffee has pointed out that in a conical dripper, the coffee bed is thicker in the center, and pouring water in the center can extract a richer coffee liquid, so this method is especially suitable for medium-dark roasted beans and can highlight a rich, full-bodied taste. If you want to try a different pour-over experience, you might as well give it a try by following the steps. [more…]
A Practical Guide to Pour-Over Coffee: Analyzing the Blooming Principle and Comparing Continuous vs. Pulsed Pouring Techniques
The charm of pour-over coffee lies in extracting rich flavors from coffee grounds with a simple pouring action. This article starts with the function of the dripper, first explaining why blooming is important—too much water will dissolve off-flavors and astringency along with it, while too little water will lead to insufficient extraction. Then, using Kenya Asali beans as an example, with a grind size of BG 5M, water temperature of 91°C, a coffee-to-water ratio of 1:13, and pre-infusion of 40-45ml/30-35 seconds, it compares in detail two common techniques: the continuous-pour method, which uses a steady thin stream to draw circles from the inside outward and finishes in about two minutes, yielding balanced acidity and sweetness with a long caramel finish, but a slightly flat body and flavor; and the pulse-pour method, which pours in stages, using large and small streams for the first two pours to agitate the coffee grounds and increase acidity and sweetness extraction, then switching to a submerged, non-agitating final pour to avoid pronounced bitterness, bringing the flavor up from raisin to blackcurrant juice, though with a shorter and weaker aftertaste. The article also includes relevant recommendations from Front Street Coffee, suitable for coffee enthusiasts to refer to. [more…]
What to Do If You Don't Have a Digital Scale for Pour-Over Coffee? Visual Estimation Tips and Pulsed Pouring Plans for 15g of Grounds
The consistent output of pour-over coffee is inseparable from the precise measurement of an electronic scale, but if you run into the predicament of a broken scale, a dead battery, or simply no alternative tool to be found, does that mean you have to give up on a good cup of coffee? Starting from the two core variables of coffee dose and water volume, this article shares Front Street Coffee's hands-on experience: how to judge 15g or 20g of ground coffee by visually estimating the height of the coffee bed, how to use the dripper's markings as a reference under different roast levels, how to choose a coffee-to-water ratio between 1:14 and 1:16, and a three-stage blind brewing process that requires no scale. Even without equipment, mastering these techniques can still brew a qualified pour-over of about 210ml. [more…]
Analysis of the Differences Between Pulsed Pour-Over and One-Pour Method in Hand-Brewed Coffee: Extraction Time, Flushing Efficiency, and Suitable Bean Types
In pour-over coffee, the pouring method after blooming directly affects the final flavor. Is it the "one-pour" method, where all the water is poured at once, or is it divided into two or more stages? These two approaches differ significantly in extraction time, flushing efficiency, and controllability. Staged pouring extends the extraction window, making the release rhythm of sweet, sour, and bitter compounds more controllable, thereby enhancing the coffee's complexity. But more stages isn't necessarily better; in everyday brewing, two to three stages are most common, as they allow flexible adjustment and make it easier to hit the ideal extraction time. This article will compare in detail the differences between the one-pour method and staged pouring, and explain what kind of coffee beans are better suited to staged extraction. [more…]
