The portafilter is an indispensable accessory for semi-automatic espresso machines. Among the common types available on the market, the bottomed spouted portafilter and the bottomless straight-exit portafilter each have their own characteristics. Front Street's stores have long used bottomless portafilters. This article will start from the structural differences and a comparison of advantages and disadvantages, and provide an in-depth analysis of how the two types of portafilters differ in extraction observation and operational convenience. It will also include a practical demonstration of bottomless portafilter extraction using Front Street's classic blend coffee beans, helping coffee enthusiasts understand the espresso extraction process and quality assessment more intuitively.

At the end of last month, Manner launched a buy-one-get-one promotion for the Year of the Dragon, and its retro mugs won over many customers with their good looks, prompting them to purchase the bundles. Recently, however, a number of netizens reported that the handles broke less than a month after use, and some even suffered cuts. Earlier, the mugs had already been criticized for poor quality control, including color discrepancies, chips, leaks, and crooked handles. At the same time, the ceramic cups from Manner's collaboration with Wedgwood were also found to have defects such as incomplete gilded detailing, cracked handles, and scratches on the cup body. The repeated failures in freebie quality have greatly undermined consumers' trust in Manner's gift promotions. [more…]

Today, a coffee cup and saucer are mostly just a coaster and a decorative item. But in Europe before the eighteenth century, the saucer was the "star" of coffee drinking. In 1640, the Dutch brought coffee from Mocha in Yemen to the Netherlands, and from there it spread throughout Europe, quickly making coffee drinking a fashion among the upper classes. At that time, Europe had not yet mastered porcelain-making technology and could only import thin, light porcelain cups from China—yet these cups had no handles, making the freshly brewed coffee too hot to hold. So people poured the coffee into the saucer to cool it, then sipped it the way modern cuppers do. It was not until the eighteenth century, when the Germans mastered porcelain production and handled porcelain cups became widespread, that the habit of drinking coffee from the saucer gradually faded away. This history has also been recorded in many paintings, so let's look together at the coffee stories in those still lifes and figure paintings. [more…]

Recently, a netizen shared an unpleasant experience at a Starbucks store on social media: while examining a cup on the shelf, the loose lid caused the cup to fall, leaving a dent on the bottom, and the staff demanded compensation at the original price. In the end, both parties negotiated to purchase the cup at a 30% discount. This incident sparked widespread discussion, with many netizens comparing how overseas Starbucks handles such situations, arguing that domestic stores' practice of making customers bear the risk of damaging fragile items is questionable. How exactly should brands balance store management and customer experience? Let's take a look. [more…]

A Luckin Coffee drink from the Meteorite series ended up with a customer unable to suck up the meteorite toppings at the bottom of the cup because the barista had packed a thin straw. After contacting customer service, the customer actually received a full refund for the order. This handling quickly sparked discussion online: some felt the merchant's service was excellent, while others worried that such a "simple and粗暴" refund approach could set a bad example. Is it thoughtful service or excessive compensation? This small matter of giving the wrong straw reflects the different strategies and potential risks that chain coffee brands face in handling customer complaints. [more…]

Faced with the dazzling array of pour-over kettles on e-commerce platforms, many coffee enthusiasts often don't know where to start. Although pour-over kettles are basically composed of a spout, body, handle, and lid, different shapes directly affect pouring performance. Front Street Coffee will systematically sort out the selection approach for pour-over kettles from dimensions such as temperature-controlled vs. non-temperature-controlled, spout type, body capacity and center of gravity, handle feel, material, and price. The article will also introduce the pouring characteristics and representative products of different spouts such as narrow gooseneck, wide gooseneck, crane-neck, flat spout, and eagle spout, helping you find the one that better suits you between budget and needs.

In the early hours of this morning, a post with images on a social platform pushed Heytea to the forefront of food safety public opinion. The posting netizen claimed that last night they witnessed an employee in the preparation room of a milk tea shop, while answering a phone call, repeatedly stirring the milk tea about to be served with the handle end of a long-handled spoon; the scene made them doubt the store's hygiene standards. As the post's popularity climbed, many milk tea consumers said it was hard to accept, especially since Heytea has always been known among its peers for strict food safety management. However, some voices held that the employee was only taking a call and did not stop working with their hands, so there was no need to overinterpret it; more catering practitioners explicitly pointed out that mobile phones are not allowed in preparation rooms in the first place, and stirring a drink with the spoon handle inverted is clearly a violation. After the incident escalated, although Heytea's official customer service account responded to the poster, it did not give a clear answer on whether the employee's actions violated regulations.

The multi-layered heart may look complex, but it is actually an advanced variation built on the basic heart—just add one more pitcher movement, and you can create distinctly layered patterns. However, it places higher demands on milk foam thickness, the amount of milk used for integration, and the skill level of your technique. In this article, Front Street Coffee breaks down the entire process of making a multi-layered heart in detail: from precise control of steaming milk foam to 6/10 full, to a comparative recommendation of two pitcher-holding postures, and then to the flow rate and cup-return rhythm in the actual pouring, helping you transition smoothly from the basic heart to the multi-layered heart and laying a solid foundation for subsequent complex patterns such as the wheat ear and swan.

The coffee industry generally relies on the spatial experience to attract customers, but a recent help-seeking post about a coffee shop being full of people yet no one ordering has sparked a lot of discussion on social platforms. The poster runs a coffee shop located in a hotel lobby. Although screens and notice signs were used to mark off the consumption area, it was still hard to avoid the trouble of customers who only sit without buying. Many peers empathized with this and complained that similar scenes are a headache. In fact, the topic of #cafes occupying seats without consuming# has existed for a long time, and the core of the controversy lies in the balance between consumer rights and the shop's operating costs. Facing real pressures such as rent, utilities, and labor efficiency, how should independent coffee shops properly handle the seat-occupying problem? Is setting a minimum consumption legal? What practical communication phrases have netizens summarized? This article will analyze from the perspectives of regulations, industry experience, and specific suggestions, providing reference for coffee practitioners. [more…]

Recently, a Maan Coffee outlet in the Aeon Mall in Fengtai, Beijing, was reported to have suddenly vacated the premises on the night of October 13 before its lease contract expired. The mall issued a notice directly accusing it of unilaterally closing down and failing to provide a plan for handling prepaid card balances, sparking widespread concern among nearby consumers and the coffee community. Why did this established Korean-style café, once regarded as a "city landmark," make its exit in such a manner? And to whom should one turn to claim the remaining balance on prepaid cards? This article sorts through the sequence of events, the mall's statement, and the trajectory of Maan Coffee's rise and fall over the years, inviting readers to observe together the real dilemmas currently facing this cup of "romantic Korean-style coffee."

When extracting espresso with a split portafilter, you will occasionally run into uneven flow between the two spouts, and in extreme cases, even one side dispensing liquid while the other dispenses nothing at all. Although this uneven split issue doesn't happen often, it's bound to come up after long-term use. Front Street will analyze the causes from two angles: first, the espresso machine not being level, which causes the liquid to flow toward one side; second, channeling, which prevents the coffee liquid from converging at the center. We will also explain the structural differences between bottomless portafilters and split portafilters, and why the design of modern split portafilters can effectively reduce the flow bias caused by channeling, helping everyone quickly pinpoint and fix the problem when it arises.

A longtime Starbucks customer in a Shanghai store was refused when trying to use two paper vouchers for free medium-sized drinks that had been distributed years earlier. The barista initially默认 they could be used, but then, citing that they were "too old," asked the customer to pay again. After the incident spread on social media, Starbucks customer service first asked the customer to mail the vouchers to verify their authenticity, then after two apologies adjusted the compensation plan, and ultimately agreed that the customer could keep the two paper vouchers, which hold commemorative value. Former employees revealed that such "thank you" vouchers originated from the period when Uni-President Group handled the business in the Jiangsu-Zhejiang-Shanghai region, representing an emotional connection between the brand and its customers. The incident sparked discussion among netizens about how brands should handle expired vouchers. [more…]

Recently, a consumer reported on the Paper complaint platform that a greenish foreign object was found at the bottom of a cup of a beverage purchased at a Luckin Coffee store in Haikou, which the store confirmed to be a component of the direct drinking water outlet.
