Luckin Coffee has teamed up with Disney's Zootopia 2 for a collaboration, launching limited-edition drinks, themed packaging, and merchandise, sparking a buying frenzy among fans. However, the themed stickers in the second wave of merchandise hide a clever design—what appears to be an abrupt black triangle pattern is actually a peel-off Luckin apron sticker. Users can place it over the movie characters to complete a "costume change." This design not only circumvents Disney's strict restrictions on brand logos but also achieves promotional goals through user interaction, jokingly dubbed by netizens as "a perfect combination of copyright awareness and creativity." Front Street Coffee has also taken note of the marketing ingenuity behind this collaboration and will break down the details and fun aspects of this partnership for you. [more…]

When Luckin Coffee launched its new strawberry series in collaboration with "Zootopia 2," many fans noticed that a "no ice" option had quietly appeared on the ordering interface. You see, Luckin has long been criticized for serving "half a cup of ice," with consumers even adding notes like "want XX ice cubes" just to get less ice. Now that the company has finally offered an option, it has raised a new question: will the ingredients be topped up after removing the ice? An employee revealed that what gets added depends on the main ingredient—milk for lattes, tea for fruit and vegetable teas, while the main ingredient of strawberry iced tea is water, so it naturally tastes bland after the ice is removed. In addition, during peak hours, some staff still miss the labels and mistakenly add ice, so consumers are advised to give timely feedback and ask for a remake. Front Street Coffee is also paying attention to how this change affects the drinking experience. [more…]

Many friends who are just getting into espresso have heard the saying: the brew ratio for espresso should be controlled at 1:2, for example, 18 grams of coffee grounds extracted into 36 milliliters of espresso. This ratio is often called the "golden ratio," but is it really the only standard? Actually, it is not. The brew ratio determines the strength of the coffee, and the strength in turn directly affects how the espresso performs when drunk on its own or paired with milk. This article centers on the relationship between brew ratio and actual extraction, explaining why 1:2 has become a commonly used reference value, and why ratios such as 1:1.5 and 1:2.5 are equally viable, helping coffee enthusiasts understand espresso extraction parameters more flexibly.

Recently, a milk tea marketed as a "2-jin pack" has gone viral on social media, attracting a large number of consumers. The product was launched by a local tea beverage brand in Zhanjiang, priced at 18 yuan, or about 10 yuan after discounts, and has tapped into the consumer psychology of pursuing value for money with its large capacity and low price. However, along with the popularity came controversy: some consumers pointed out that 2 jin is roughly equivalent to 1000ml, and compared with the 500-700ml large cups of milk tea on the market, the actual value for money may not be outstanding, and merchants should label the capacity truthfully. In addition, similar products have already appeared in Nanning, Guangxi, and the originality of the idea has also sparked discussion. Some people are also worried that oversized milk tea may cause food waste. As coffee lovers, Front Street Coffee has also noticed the consumer trends and industry reflections behind this phenomenon.

As the birthplace of coffee, Ethiopia has the most well-developed coffee bean grading system among African producing countries, yet it also leaves many enthusiasts confused.

The brewing duration of pour-over coffee has always been a focal point for enthusiasts: what should you do if the coffee hasn't finished draining after 2 minutes? How long is considered normal for brewing? Starting from Front Street's brewing practice, this article analyzes the impact of time on extraction, explains why 2 minutes is often regarded as a reference standard, and also points out that time is not the only variable. Using light-roasted Huakui and Guodingding as examples, it demonstrates how to match different bean conditions by adjusting water temperature, grind size, dripper, or staged extraction, helping readers understand the importance of parameter coordination rather than obsessing over a single time metric.

Where does the unique honey aroma of honey-scented tea actually come from? Since the 1990s, Japanese scholar Akio Kobayashi has gradually uncovered the secrets of the aroma compounds in Oriental Beauty tea and Darjeeling black tea, discovering that two substances—2,6-dimethyl-3,7-octadiene-2,6-diol and 3,7-dimethyl-1,5,7-octatriene-3-ol—are the core sources of the honey aroma. Even more astonishingly, after tea plants are fed on by green leafhoppers, they actually initiate an abnormal metabolism to produce special compounds, summoning natural enemies to defend themselves. This article will take you deep into the scientific discoveries about the aroma compounds of honey-scented tea, as well as the fundamental differences in aroma characteristics between Darjeeling black tea and Taiwan black tea.

Many coffee enthusiasts have heard of the "golden ratio" for espresso—using a dose roughly equal to the basket's capacity, and extracting twice the dose weight in liquid weight within 25 to 30 seconds. However, when everyone strictly follows the 1:2 brew ratio to dial in, they find that not only does it consume a large amount of coffee beans, but the taste is also hard to reach an ideal state. So, must espresso extraction stick firmly to the 1:2 brew ratio? The answer is no. This ratio is just a general reference standard, helping us extract a delicious espresso with appropriate concentration and a reasonable extraction yield. The truly effective dialing-in method is to remove the restrictions on dose and liquid weight, and treat them as adjustable variables as well. This article will explain this flexible adjustment approach in detail for you. [more…]

Is coffee a healthful beverage or a hidden health risk? This question has long puzzled many enthusiasts. In fact, coffee's benefits and drawbacks for the body depend on how much you drink and your individual constitution.

A 2010 Yunnan aged black tea, matured through 8 years of aerobic storage followed by 2 years of anaerobic storage, produced in Huocaoshan, Zhenkang County, Lincang, Yunnan, near the border with Myanmar. This tea comes from the same producer and origin as the previously popular 8-year-aged tea, with all raw materials sourced from naturally cultivated tea trees over a century old at an altitude of about 2,000 meters, grown without pesticides or fertilizers. Due to the slow growth of natural cultivation, the yield is less than a quarter of that of ordinary tea gardens, and the tea leaves are exceptionally rich in polyphenols and minerals, with a long-lasting aftertaste where sweetness slowly spreads deep in the throat. After anaerobic maturation, the aroma becomes more intense, combining the character of black tea with the smooth, refreshing charm of ripe Pu'er. This article will detail its aroma and taste characteristics, brewing suggestions, and a price reference for authentic 10-year-aged Dianhong black tea in 500-gram quantities, suitable for readers who enjoy aged teas.

In pour-over coffee, brew time is not an actively controllable parameter, but rather a mirror that reflects whether grind size, coffee-to-water ratio, pouring technique, and dripper choice are in harmony. Many tutorials treat 2 minutes as the ideal checkpoint, but beans of different roast levels offer noticeably different resistance to hot water penetration—dark roasts flow quickly, while light roasts tend to clog, so the time naturally fluctuates. Front Street Coffee uses two beans—Colombia Huila and Ethiopia Sidamo Hamasho—to demonstrate the pouring rhythm, staged strategies, and flow-rate correction methods for dark and light roasts respectively, helping beginners keep brew time within a reasonable range and understand the direction of adjustment behind the time feedback.

A smartphone launch event unexpectedly caused a sudden surge of group orders at nearby Luckin Coffee stores in the evening, catching staff off guard and keeping delivery riders constantly on the move. It turned out that the Honor CEO demonstrated an AI ordering feature on stage, buying 2,000 cups of Light Jasmine from Luckin with a single sentence.
