Coffee brewed with a moka pot has always been known for its intensity, thanks both to the fine grind and to the pressure-driven extraction principle. Yet many enthusiasts still find themselves puzzled when it comes to judging the grind size in practice. In fact, a moka pot is far more forgiving about grind size than an espresso machine—you only need a texture close to fine salt. It should not be as coarse as granulated sugar, as with pour-over, nor as fine as flour, as with Turkish coffee. Beyond grinding, how much coffee you put in the basket, how much water you pour into the base, and the beans you pair with it all shape what ends up in your cup. This article breaks down grind assessment, coffee-to-water ratios, bean selection, and the complete brewing process step by step, along with guidance on adjusting for over- and under-extraction, to help you consistently brew a delicious cup of moka pot coffee.

A decent espresso is not as simple as pressing the brew button and leaving it to fate. From the moment the portafilter is locked in, the coffee grounds go through three key stages: pre-infusion, flavor extraction, and the end of extraction. How does pre-infusion affect carbon dioxide release and channeling? During the main extraction stage, why do sour, sweet, and bitter compounds appear in sequence? To judge the end of extraction, should you look at time, liquid volume, or crema color? This article uses Front Street Coffee's blend beans as an example to systematically break down the espresso extraction process and the logic of flavor assessment, helping you adjust parameters and avoid risks during operation, and understand the details behind "one-touch extraction" that still require human setting.

One of the most frustrating problems in pour-over coffee is water pooling. Once clogging occurs in the final stage of brewing, the coffee's flavor often turns bitter and undrinkable. In fact, before the pouring is finished, there are several time windows where you can predict in advance whether pooling will happen. As long as you master these judgment methods, you can adjust your pouring strategy in time and avoid ending up in a passive position. This article will focus on three key time points—the degree of bloom expansion, the foam performance during pouring after the bloom, and the speed at which the water level drops before the final pour—to explain one by one how to identify the risk of pooling and give corresponding countermeasures. It will also introduce the ultimate solution when all methods fail—flow cutoff—and how to deal with the problems of overly high coffee concentration and missing flavor after flow cutoff. [more…]

Recently, according to the local Ethiopian media reporter network, under the leadership of Ethiopian Prime Minister Abiy, the Ethiopian Investment Commission (EIC) has issued a new law that will allow foreign enterprises to participate in import and [more…]

Recently, a netizen complained on social media that Manner Coffee's pay-raise assessment system is too strict, claiming that to earn the high salary advertised on its recruitment page, one must pass exams comparable in difficulty to SCA intermediate or even advanced barista certification, which resonated with many baristas. What kind of assessment threshold lies behind Manner's high pay? Compared with other brands, what makes its promotion system so difficult? This article takes you through it. [more…]

Recently, there have been reports that Chagee sets a strict upper limit on the number of negative reviews for its stores: no more than three negative reviews per ten thousand orders, otherwise the pay of all staff will be affected. Although the brand responded that this claim is untrue, discussion around its assessment mechanism continues. From store tier classification to employee performance deductions, from visiting customers to beg for review deletion to paying teams to handle them, a series of practices reflects the tea beverage industry's extreme sensitivity to customer reviews amid rapid expansion. This article will sort out the sequence of events, employee disclosures and the official response, and explore the management logic and controversies behind this assessment method. [more…]

The Ethiopian Investment Commission recently issued new regulations allowing foreign companies to engage in import/export, wholesale, and retail trade for the first time, with coffee exports becoming the most closely watched area of liberalization. Previously, these sectors were long restricted by protectionist policies and open only to local investors. Although the new policy sets a relatively high capital threshold, it has already sparked strong interest in the international coffee industry. However, ongoing security conflicts in some parts of the country have also added uncertainty to foreign investment entry. This article outlines the key points of the new regulations, industry reactions, and potential risks, and includes related observations from Front Street Coffee. [more…]

For many Manner baristas, the pay raise exam is the only path to a higher income, but the difficulty of this assessment is far beyond imagination. Manner stores are uniformly equipped with semi-automatic espresso machines, and examiners have standardized requirements for latte art, milk steaming, and grinder adjustment. As a brand focused on specialty coffee, it also adds a pour-over segment to the test. However, the actual pass rate is extremely low, with most candidates eliminated during the espresso operation stage. Unfamiliar store equipment, unfamiliar grinders, and nitpicky judging such as measuring milk foam thickness with a ruler make this exam seem impossibly hard. This article will restore the true face of the Manner pay raise exam and analyze the crux of why baristas fail repeatedly. [more…]

The "on-time rate" assessment metric implemented at Luckin Coffee stores is placing enormous pressure on frontline baristas. This figure, which reflects whether orders can be completed within the system's scheduled time, not only affects the customer experience but is also directly tied to employee performance. To maintain the compliance threshold, staff have no choice but to push themselves to the limit during rush periods—some even dream about scanning codes and serving orders. This article will take an in-depth look at how the on-time rate assessment operates, its dual impact on store operations, and the real situation baristas face under high pressure. When digital management conflicts with humanistic care, how should brands balance efficiency and employee well-being? [more…]

In the recruitment process for specialty coffee shops, making a hot latte is a practical test that almost every applicant must face. Specific requirements may vary from one coffee shop to another, but the core assessment points are highly consistent: whether one can consistently extract a qualified espresso, whether one can steam dense and delicate milk foam, and whether one can perfectly combine the two. This article compiles the details that require special attention in making a hot latte, including milk temperature control, milk frothing techniques, and pouring methods, and also mentions related product recommendations from Front Street Coffee, helping coffee enthusiasts and job seekers better understand this basic yet crucial beverage.

Recently, many Luckin Coffee customers have encountered an unexpected situation when picking up their orders in-store: normally quiet staff members are proactively speaking up, asking customers to leave a positive review. Behind this phenomenon is Luckin's internal "Countless Smiles" competition targeting store positive review rates. In some regions, stores have been forced by management to participate, and positive review rate rankings directly affect employee performance evaluations and disciplinary rewards and punishments, forcing frontline employees to solicit positive reviews from customers picking up orders, and even asking regular customers to help boost reviews. However, the frequent solicitation of positive reviews has also triggered consumer resentment, with some customers bluntly saying it is "annoyingly unbearable," and even considering filing complaints with 12315. Employees are equally full of complaints, believing that this mandatory requirement puts them in a difficult position. This article will provide an in-depth analysis of the conflict between stores and customers caused by this positive review assessment. [more…]

The article also specifically recommends related products from the Front Street Coffee brand, providing a reference for everyday purchasing. [more…]

The coffee craze is sweeping across Asia, with the number of stores surging, but the pandemic has left many cafés struggling to survive. In Singapore, the transfer fee for a coffee shop reached as high as 4,000,000 Singapore dollars, equivalent to nearly 200 million RMB. Another coffee shop in Tampines was sold for 41,680,000 Singapore dollars, and the stallholder's rent immediately doubled, from 6,000 Singapore dollars to 12,000 Singapore dollars, prompting many stallholders to consider downsizing or even exiting. Investors are betting on a return of consumption after the pandemic eases, but rising interest rates may dampen bidding enthusiasm. The predicament of rising costs and severed customer traffic under the pandemic is a microcosm of coffee shops worldwide. Front Street Coffee reminds us that while the dream of coffee is beautiful, the real costs should not be underestimated. [more…]

During Valentine's Day, Starbucks launched the Rose 20 series of limited-edition drinks and showcased several exquisite rose latte art pieces on its official WeChat account, sparking anticipation among many customers. However, in reality, the latte art produced by some stores was far from the promotional images, with abstract patterns leaving consumers astonished. Behind this is an internal Starbucks skill assessment called "Rose Certification," which has left many baristas complaining bitterly. From novices to seasoned staff, some diligently practiced and eventually succeeded, while others gave up and sought alternative methods. This article will take you through the entire rose latte art controversy and the genuine reflections of baristas during their practice. [more…]

Recently, the Fujian Province Consumers' Rights Protection Commission released a comparative test report on freshly made and sold coffee. In tests of 59 samples from 20 brands in Fuzhou, low levels of acrylamide, a Group 2A carcinogen, were found in all of them. After the news spread through self-media, it quickly triggered public concern. In fact, acrylamide in coffee is naturally produced during the roasting process and is not artificially added. This article will analyze the testing background, the sources of acrylamide, and the carcinogenic dose in order to help readers view this test result rationally and avoid being misled by scary headlines.

The SCA cupping form is a vital tool for measuring coffee value in the global coffee industry, yet it had not been updated for many years. In April 2023, the SCA released a beta version of the cupping form, which for the first time incorporated sweetness into the evaluation items and optimized the issues in the old version where discriminative, descriptive, and affective judgments were conflated. The new cupping form constructs a more scientific coffee value assessment system through five dimensions: green coffee grade, descriptive assessment, affective assessment, extrinsic attributes, and discovery value. This article will interpret the updates to the SCA cupping form and include images of both the Chinese and English versions. Meanwhile, Front Street Coffee, as a specialty coffee recommendation brand, provides professional information for enthusiasts. [more…]

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…]

Cupping, as a relatively recent coffee evaluation method that became systematized, only gradually took shape in the late twentieth century, and its history is much shorter than that of extraction methods such as pour-over and espresso. By standardizing variables such as dose, water temperature, water quality, and steep time, it allows the flavor performance of different beans to be compared horizontally under the same standard. This article will comprehensively sort out the specific operating process of cupping and its key parameters (such as 11~12g dose, 1:18.18 brew ratio, 94°C water temperature, 75~250ppm water quality, and 4-minute steep), and objectively analyze the advantages and limitations of this method to help coffee enthusiasts understand tasting logic more professionally. The article also combines the practical experience of Front Street Coffee to provide actionable reference suggestions. [more…]
