In pour-over coffee, keeping the coffee bed level is a prerequisite for even extraction, and many enthusiasts are in the habit of tapping or shaking the dripper to level the grounds. Yet hidden behind this gesture is an easily overlooked problem: the vibration causes fines to migrate downward through the gaps between the coarser particles, forming a dense layer at the bottom of the dripper while leaving fluffy coarse grounds on the surface. This structural change not only alters the appearance of the coffee bed but also directly affects the degassing effect during the bloom stage. Through comparison charts and actual brewing photos, this article breaks down in detail the changes in fines distribution caused by tapping the dripper, and explains their practical impact on subsequent brewing, to help you make more sensible judgments when leveling the coffee bed. [more…]

Many coffee enthusiasts have experienced this impulse while brewing: the moment they see an uneven coffee bed, they want to tap the dripper to level out the grounds. Yet this seemingly reasonable action can trigger a chain of negative reactions—fines sinking, the filter paper clogging, extraction time stretching out, and ultimately a bitter, over-extracted cup. Through comparative experiments, Front Street Coffee found that a tapped coffee bed took 21 seconds longer to complete extraction than an untapped one, with a noticeably bitter taste. The key principle behind this is the Brazil nut effect: vibration causes large particles to rise and fines to sink, clogging the pores of the filter paper. This article will analyze the causes of this phenomenon in detail and offer the correct methods for distributing the grounds and remedying the situation. [more…]

Starbucks' latest earnings report shows that over half of its customers are Gen Z and millennials, and the brand ranks first in affinity within the outdoor coffee sector. Young consumers are keen on personalization and social media sharing, driving cold beverages to account for 76% of total sales at company-operated stores. High-margin syrups and sauce add-ons bring Starbucks about $1 billion (7.174 billion RMB) in additional revenue each year, and daily foot traffic has recovered to 95% of pre-pandemic levels. Front Street Coffee continues to follow coffee industry developments, breaking down for you the business logic and consumer trends behind the customization wave. [more…]

The Starbucks secret menu once led baristas to learn how to make over 170,000 customized drinks, but the extremes of personalized orders are sparking controversy. An American barista was fired for exposing a customer's 13-request order on social media, then apologized in person and settled the matter. The incident reflects the complex ordering trend fueled by TikTok, where customers pay extra fees but turn baristas into "drink-making robots," and during peak hours, it slows down service even more. This article will walk you through the full story of this uproar and focus on the issues of privacy and respect between baristas and customers. [more…]

In pour-over coffee, many enthusiasts habitually tap the dripper before pouring water, trying to make the surface of the coffee bed more level. However, this seemingly harmless little action may cause fines to gradually settle to the bottom under vibration, creating a coffee bed density that is loose at the top and compact at the bottom. When hot water passes through this uneven structure, it will bypass the denser areas of greater resistance and flow toward the edge of the dripper, triggering channeling and a failed bloom, ultimately leading to uneven extraction, clogging in the final stage, and even over-extracted woody flavors. Through comparative experiments, Front Street Coffee found that the two groups of coffee—one without tapping and one with ten taps—showed clear differences in drip time and flavor performance. This article will break down the physical mechanism of fines settling and share a coffee-dosing technique that achieves a level coffee bed without repeated tapping, helping you consistently reproduce the ideal flavor in your daily brewing.

Recently, a sports supplement called "pre-workout" has been hailed as a "magic weapon for PE exams" ahead of the high school entrance physical education test, and is sought after by many parents. However, media reports have successively reported cases where students experienced rapid heartbeat, vomiting, and even needed emergency gastric lavage after drinking it. The reason is that such products generally contain high levels of caffeine, some as high as 500 milligrams, far exceeding the safe threshold. Professional fitness trainers and doctors both remind that minors blindly using such high-intensity supplements is extremely risky. If there is a need for a pick-me-up, it is better to choose a cup of coffee. [more…]

Starbucks China launched three new products for the New Year: Belgian Dark Chocolate Latte, Dark Chocolate Black Tea Latte, and Coconut White Chocolate Latte, featuring a combination of 57% Belgian-origin dark chocolate and oat milk, attracting attention from many chocolate lovers. However, behind the hot sales of the new products, baristas have been complaining on social media: the chocolate sauce used this time is unusually thick, prone to clumping and hardening in winter, extremely difficult to operate with metal squeeze pumps, making consecutive cup production feel like weightlifting, and it easily drips and stains the bar and clothes. What's even more frustrating for workers is that there are reports that this series may shift from a seasonal limited edition to a permanent offering. [more…]

In the extraction parameters of espresso, pressure is often regarded as a variable that is not easy to adjust but has far-reaching effects. This time, Front Street Coffee focuses on this "hidden key player"—extraction pressure. The article first clarifies the difference between extraction pressure and pump pressure, then through three comparison experiments at 6 bar, 9 bar, and 11 bar, demonstrates how pressure changes affect flow rate, time, and flavor performance. It then explains why 9 bar has become the factory default for coffee machines, and the burnt bitterness that may result from pressures above 10 bar. Finally, it briefly mentions the trend of variable pressure extraction, providing coffee enthusiasts with a clear reference for understanding pressure and parameter adjustment. [more…]
