Dirty has always been a popular product in coffee shops thanks to its high aesthetic appeal and the unique experience of hot and cold colliding. When making a Dirty, using a chilled glass can extend the layering effect between the espresso and the milk, but should you use a refrigerated glass or a frozen glass? Through comparative experiments, Front Street Coffee found that although a frozen glass can widen the initial temperature difference, it also accelerates the dissipation of the layers, and the milk's mouthfeel and aroma are slightly compromised. The rise in popularity of -86°C Dirty has brought frozen glasses into the spotlight once again. This article explains in detail the differences between refrigerated and frozen chilled glasses, the points to note when making a Dirty with a frozen glass, and why purified milk is the best partner for a frozen glass, helping you fully understand the intricacies behind this dirty coffee.

Does putting coffee beans in the freezer really extend their peak flavor window? Some friends have found that beans that have been frozen brew up with weaker aroma and a thin body, and so they suspect freezing is useless. In fact, freezing really can slow down coffee bean degassing and extend freshness, but only if storage and brewing are both done right. This article covers everything from airtight portioning and preventing condensation, to the two routes of brewing frozen beans directly versus brewing after thawing, and uses comparison data from Front Street Yirgacheffe · Gutingding to help you fully understand the complete operational logic of frozen coffee beans in one go.

Last winter, the Northeastern specialty frozen pear unexpectedly went viral, and Luckin seized the moment to launch its "Big Frozen Pear Americano," which won over a large batch of loyal fans with its refreshing taste. As this year's cold winter arrives, many "frozen pear heads" have been calling for its return in the official comment section, and Luckin, ever responsive to feedback, promptly rolled out the winter-limited "Big Winter Pear Americano." However, delighted fans who placed orders soon noticed the taste didn't match the white moonlight in their memories. A closer look at the description revealed the new version uses seasonal fresh pear juices such as Akizuki pear and Dangshan pear, completely different from last year's pear-flavored concentrated fruit pulp formula. Longtime fans declared it hard to accept and clamored for the official to bring back the original; new users felt the fresh pear juice greatly weakened the coffee's presence, making it taste more like rock sugar snow pear. Is this winter limited edition a pleasant surprise or a disappointment? Let's take a look. [more…]

Recently, a netizen exposed that the well-known fruit tea chain brand 7FenTian uses quick-frozen mango chunks in its beverage preparation, and that this food has a shelf life of up to 24 months, sparking widespread concern. The brand is known for its signature product Yangzhi Ganlu, and both its ordering mini-program and offline stores advertise the use of fresh mangoes and freshly cut soft and glutinous mangoes, but the expose revealed that the stores actually use quick-frozen fruit chunks. 7FenTian customer service confirmed that the quick-frozen mango chunks are uniformly ordered and delivered by the company, and the shelf life is indeed 24 months, but regarding why quick-frozen fruit chunks are still used when fresh mangoes are available, customer service said it could not explain. At present, the expose post has been deleted, and the brand has not yet made a public response regarding issues such as the proportion of quick-frozen mango use and the failure to clearly inform consumers of the type of ingredients. As coffee enthusiasts, understanding the true situation of beverage ingredients is equally important. Front Street Coffee continues to follow industry developments and brings you objective reporting.

Starbucks has recently been ramping up its co-branding activities, teasing a limited-edition extendable straw shaped like the Golden Cudgel that plays the Monkey King's voice lines, while also launching a new delivery-exclusive drink, the "Flow Frozen Latte," on its Starbuck Delivery service. This creative coffee, said to be inspired by ginger milk curd, claims that the liquid naturally congeals and separates into layers during delivery, arriving as a latte with distinctly defined layers. However, consumer reviews since its launch have been mixed: some have posted photos showing obvious congealing and layering, describing the texture as similar to double-skin milk or coffee pudding; others question whether the product matches its description, saying what they received was no different from an ordinary latte. Is the "flow frozen" effect real or just a gimmick? And is the new recipe simply an old product with a new name? This article will compile netizens' hands-on feedback to take a look at the true face of this talked-about beverage. [more…]

Is the frozen coffee bean storage method circulating online actually able to extend the peak-flavor period and lock in the flavor? This time Front Street is going to seriously discuss this topic. Freezing can indeed slow down the oxidation rate of coffee beans, extending the optimal tasting period from 30 days to 2~3 months, but experiments show that frozen beans are actually in a "pseudo-fresh" state, and there is still a gap in flavor compared with the peak-flavor period. The real advantage of freezing lies in making the ground particles more uniform. However, there are too many variables in daily operation, such as needing to grind within one minute of thawing, adjusting brewing parameters, and improper sealing causing odor transfer. This article will break down the principles of frozen storage, the points to note, and give more practical bean storage suggestions one by one. [more…]

The brand responded that the use of quick-freezing preservation technology is intended to ensure stable supply for stores in a wider range of regions. Is it a cost consideration, or a limitation of overseas fruit quality? This article takes you through the ins and outs of the incident. [more…]

Can portafilter temperature really influence the flavor of an espresso?

Last summer, Luckin made refreshing lemon tea a permanent menu item, and earlier this year it upgraded the recipe, adding quick-frozen lemon halves and lemon pulp to enrich the texture. However, the 2.0 version of the lemon tea did not win unanimous praise from consumers and staff, and the problem lay with that conspicuous piece of quick-frozen lemon. Recently there has been news that Luckin may be trying to replace the quick-frozen lemon with a fresh fruit slicer, which has sparked widespread discussion among store employees. Some worry that they will have to arrive early to wash fruit and still spend a lot of time cleaning the machine after closing, bluntly saying they "want to run away"; others think a full rollout is unlikely. Front Street Coffee continues to follow developments in the coffee and tea beverage industry, and this article will sort out the ins and outs of the incident. [more…]

Luckin Coffee recently posted a romantic tutorial on social media, teaching everyone how to make a "Frozen Rose" using a Luckin can or an ordinary ice cup, sealing a rose and ice cubes inside the cup to create an eye-catching decoration for the office desk. This玩法 quickly triggered netizens to imitate and like it, but it also worried baristas in stores—because this玩法 is not an official product, and if customers come to the store asking for it to be made, it may cause misunderstandings and negative reviews. The popularity of flower cups can be traced back to netizens' creativity, and was later boosted by brands such as Mixue Bingcheng and Haidilao to become a traffic code. Front Street Coffee noted that although similar marketing can bring heat, it needs to balance the execution pressure on frontline employees. [more…]

Dalgona coffee has taken the internet by storm with its cloud-like, velvety foam and caramel-sweet flavor, while the frozen version of Dalgona coffee needs only one extra step of chilling to transform the coffee foam into an ice cream-like texture, with layers that rival a snow-topped coffee. But when making it, should you use espresso or instant freeze-dried powder? What exactly are the differences between the two in terms of whipping difficulty, flavor expression, and final mouthfeel? Front Street Coffee conducted two sets of comparative experiments using freshly brewed espresso and instant coffee powder respectively, recording everything from extraction parameter adjustments and whipping time to the texture of the final product, to help you find the method that suits you best.

If the brewed espresso isn't finished on the same day, can it be safely stored in the fridge or freezer overnight and still be enjoyed the next day? Beyond food safety concerns, what coffee lovers really care about is whether the flavor will take a serious hit. Front Street Coffee used the same espresso blend, storing espresso in the refrigerator and freezer overnight respectively, then comparing them with freshly brewed espresso—tasting each as straight espresso, Americano, and milk coffee—to see just what overnight coffee turns into, and how big the gap is between freezing and refrigerating.

Last spring, Heytea's guava series of fruit teas captured a large number of consumers with their refreshing taste, and their removal from the menu after the season became a regret for many. On the eve of this year's Valentine's Day, the guava series finally returned amid widespread calls for it, and as soon as the Refreshing Guava Grape Tea was launched, it flooded social media, with store orders packed. However, while fans were raising their cups for photos and check-ins, Heytea employees in the back kitchen were facing baskets of fresh guavas, wanting to cry but unable to shed tears. Manually squeezing fruit puree, peeling green grape flesh, and long hours of repetitive labor caused many staff members to develop health problems such as frozen shoulder, tenosynovitis, and hand allergies. Behind a cup of seemingly simple fruit tea, what exactly is hidden in terms of the production process and labor intensity? This article takes you to understand the real working conditions of milk tea workers. [more…]

After Tea Baidao's lychee iced milk was discontinued with the changing seasons, the brand quickly launched two new iced milk drinks, among which the iced mint iced milk co-branded with Frozen drew a lot of attention thanks to its mint element and co-branded merchandise. However, this drink, made with fresh mint leaves, green grapes, lemon, matcha liquid, and milk, did not deliver the expected cooling sensation upon tasting; instead, the grassy flavor of freshly squeezed mint juice sparked polarized reviews. Some described drinking it as turning into a cow chewing on grass, while others found the plant's fresh fragrance uniquely appealing. Whether this cross-boundary mashup is a stroke of creativity or a flop is worth investigating. [more…]
