Microwave Heating of Milk Tea Causes Paper Cup to Scorch, Molly Tea Wrongly Blamed and Sparks Heated Discussion

As the weather turns cold, hot milk tea tends to get cold during delivery, and many consumers try to reheat it in a microwave, only for accidents to happen frequently. Recently, multiple customers have reported that when heating Jasmine Naibai drinks, the paper cups showed burn marks and even nearly caused a fire. In contrast, heating milk tea from brands such as Bawang Chaji, Mixue Bingcheng, and Nayuki did not cause similar problems, raising questions about the quality of Jasmine Naibai's paper cups. However, onlookers rushed to defend the brand, pointing out that the cup sticker already has a reminder, and that the metallic substances in the cup's gold-stamped pattern reflect microwaves in the microwave, which is the main cause of the accidents. This article reviews the course of the incident and the underlying principles, and reminds readers: heating milk tea in a microwave poses safety hazards, so do not imitate it rashly. [more…]

Luckin Coffee's co-branded merchandise with Havoc in Heaven sees a cold reception, postcards' value for money called into question, staff say only single digits given out per day

Luckin Coffee recently collaborated with the "Havoc in Heaven" IP to launch Olympic-themed limited-edition merchandise, but the co-branding campaign that was initially highly anticipated unexpectedly fell flat. Although many consumers frequently placed orders to collect the merchandise in the early days of the campaign, the subsequently released gold-stamped postcards failed to sustain the momentum. Staff at many locations reported that very few postcards were given out, in stark contrast to the previous week's frenzy when cup sleeves and stickers sold out. Consumers generally felt that the merchandise offered poor value for money, with nearly ten yuan of a two-cup combo going toward six pieces of paper, lacking practicality and appeal. This article will analyze in detail the reasons behind the co-branding campaign's cold reception, compare it with the earlier successful collaboration with "The Tale of Rose," and explore the timing, conditions, and human factors required for successful co-branding marketing.

Milk tea paper cup catches fire after 30 seconds in microwave, Heytea responds that it contains metal material and heating is not recommended

Recently, a netizen in Fuzhou placed a cold Heytea drink, cup and all, into a microwave to heat it up. Just 30 seconds later, flames erupted inside the microwave, and the upper half of the cup was burned. The person involved described that halfway through heating, the microwave suddenly began crackling, and the moment it was opened, flames burst out. The fire only went out after the cup was knocked over with a spatula. Heytea customer service responded that the drink uses a paper cup containing metal materials, which is not suitable for microwave heating. In fact, many milk tea lovers on social media have a habit of directly heating milk tea, and similar dangerous incidents are not isolated cases. Whether brands should label packaging with microwave use warnings has also sparked discussions among consumers and legal professionals. [more…]

What Are the Different Types of Latte Art? An Analysis from Traditional Patterns to Etching Needles and 3D Latte Art Techniques

Latte art has long ceased to be as simple as heart-shaped patterns. Since David Hume accidentally created a heart on the surface of a milk coffee in the 1980s, latte art techniques have continuously evolved, and today have developed into multiple types such as traditional latte art, coffee etching, and 3D latte art. Traditional latte art uses a milk pitcher as its main tool, and can be further divided into basic patterns and advanced combined patterns; coffee etching relies on etching needles recognized by international competitions to draw finer or bolder lines; 3D latte art is more figuratively a kind of "sculpting" technique, requiring the stacking of thick milk foam and the use of spoons and etching needles for shaping, and also uses chocolate sauce, caramel sauce, and the like for outlining. This article, brought to you by Front Street Coffee, helps you understand the features and key production points of these latte art types. [more…]

Can't get latte art patterns to come out? A detailed tutorial on the reasons for latte art failures and technique corrections

Many coffee enthusiasts encounter a frustrating problem when practicing latte art: even though they follow the steps, a pattern simply refuses to form on the surface of the liquid. In fact, the essence of latte art is using the color contrast between milk foam and espresso crema to paint, and the key lies in precisely controlling the height of the milk pitcher and the flow rate during the integration stage and the pattern-forming stage. From the perspective of Front Street, this article systematically sorts out the three main reasons why latte art fails to produce a pattern—not shaking the milk evenly before integration, holding the milk pitcher too high when forming the pattern, and pouring with too small a flow rate—and provides corrective methods for each, helping you break through the bottleneck in your basic technique and successfully pour your ideal pattern.

Latte Art Composition Techniques: Three Major Causes and Solutions for Off-Center Patterns

In coffee latte art, the beauty of a pattern depends not only on smooth lines but also on whether the composition is reasonable. Centered composition is the most common approach, as it highlights the sense of stability of symmetrical patterns. However, many beginners find that their latte art patterns always deviate from the center. Front Street Coffee points out that this is mainly caused by three reasons: milk foam that is too thin leading to excessive fluidity, pouring back into the cup too quickly increasing the impact force, and an incorrect drop point. This article will analyze the causes of and solutions to these problems one by one, while also emphasizing the importance of choosing suitable coffee beans, and recommending two products, Front Street Classic Blend and Commercial Blend, to help you create centered and beautiful latte art at home.

HEYTEA's limited powder-sprinkling designs often go wrong, and staff admit the operation is difficult

Heytea recently launched a limited winter warming campaign. In addition to themed merchandise, its offline stores also set up a free Easter egg—sprinkling the Heytea pet pattern onto the milk cap of designated drinks. Many fans made special trips to pick up this cup with the "limited-edition pattern," but the products they actually received frequently turned out to have the pattern blurred into a mess, with no recognizable shape at all. Some consumers complained that the product did not match the description and questioned whether the staff were just going through the motions; store employees, meanwhile, complained bitterly, saying whether the pattern takes shape depends heavily on powder-sprinkling skill, and that pet patterns are much harder to execute than the usual Heytea character, with a shaky hand or a slight angle deviation potentially causing a fail. In this controversy over sprinkling powder on a cup of milk cap, who exactly should take the blame? [more…]

Latte art milk frothing and pouring techniques: a complete approach from basic practice to on-the-spot adaptation

Many beginners can occasionally pour a beautiful pattern, but when they try to reproduce it, they just can't find that same touch again. Front Street believes that judging whether a latte art pour is up to standard starts with the fineness of the surface milk foam, then whether the integration is even and the boundary between the golden ring and the pattern is clear, and only lastly comes the pattern itself—clear texture and well-defined shape are enough; complexity is not the point. Theory cannot replace feel, but there are some practical tips that can effectively reduce the failure rate.

Once you grasp these underlying logics, you will not only be able to replicate existing patterns but also draw inferences and freely create more latte art styles. [more…]

Why does latte art always lean to one side? Analyzing the three main causes of composition偏移 in coffee latte art and how to adjust them

In latte art, the beauty of a pattern comes not only from the shapes formed by the milk foam, but also from proper composition. Centered composition is the most commonly used because it highlights a sense of symmetry and balance, yet many beginners often find that their patterns drift off-center.

Meanwhile, Front Street Classic Blend and Commercial Blend, two coffee beans, are considered ideal choices for making latte art espresso due to their rich crema. Mastering these details helps improve the stability and visual presentation of latte art. [more…]
