Recently, a customer at a Sexy Tea store discovered that an employee was actually using a pipette—commonly found in laboratories—to measure milk tea ingredients. The scene was photographed and quickly sparked heated discussion on social media. As precision experimental instruments, pipettes can measure liquids more accurately, but their operating standards are strict, and improper use may pose food safety risks. Many netizens with laboratory experience pointed out that untrained employees operating such equipment risks liquid backflow and contaminated tips, and whether disposable tips meet food-contact standards is also questionable. Opinions continue to clash over whether laboratory instruments can be used in food service settings. [more…]

In the world of pour-over coffee, the V60 dripper is a classic piece of equipment that almost every enthusiast cannot avoid. This article will start from the background of the V60's birth, tracing how Hario drew inspiration from a laboratory funnel and ultimately designed this conical dripper that changed the pour-over landscape. At the same time, it will analyze in detail how the V60's three major extraction characteristics—the 60° cone angle, the large-aperture outlet, and the spiral rib structure—work together to shape the flavor direction of the coffee. In addition, the article will also explore the connection between the third wave of coffee and the V60's rise to popularity, explaining why the delicate floral aromas and fruity acidity of light-roasted beans require fast extraction to be fully expressed, and compare the practical effects of different materials such as resin, ceramic, and glass on brewing, as well as the reason Front Street Coffee has long chosen the resin version of the V60.

The siphon is a classic coffee brewing device that combines visual appeal with extraction stability, operating on the physical changes of steam pressure when heated and vacuum return flow when cooled. Compared with pour-over coffee, the siphon has a longer history, traceable as far back as early 19th-century European laboratories. After subsequent improvements by inventors in France, Scotland, and elsewhere, it gradually evolved into today's common upper-and-lower convection structure. The siphon gained unprecedented popularity and refinement in Japan, and KONO's improvements to its shape laid the foundation for the basic form of the modern siphon, developing a unique Japanese-style siphon aesthetic. Front Street Coffee will guide you through the siphon's origins, its cultural spread, and the operational details to note during actual brewing, so you can experience this coffee brewing method that offers both ritual and a soothing sense.
