A classic espresso con panna is supposed to be served in a small demitasse, allowing the customer to savor the blend of espresso and cream in a single sip. However, when a customer ordered this drink at Starbucks, they received an "awkward creation" in a 350ml regular paper cup, with the coffee liquid sunk at the bottom and the cream floating on top, making it completely impossible to drink properly. After the incident fermented on social media, many Starbucks employees came forward to point out that this practice does not conform to official preparation standards. Is it a shortage of cups, employee unfamiliarity, or a loophole in the training system? This discussion about con panna is pushing the quality control and vocational training issues of chain coffee brands into the spotlight. [more…]

When browsing brands like Front Street Coffee or coffee teaching courses, you will often see single-origin beans recommended for brewing with 15g of coffee grounds. This number seems to have become the golden standard for pour-over coffee, but why exactly 15g? What problems would 10g or 20g bring? Starting from Front Street Coffee's teaching practice, this article deeply analyzes the impact of coffee dose on coffee bed depth, water flow state, and extraction results, explaining why 15g can become the most suitable single-serving parameter for the 01 dripper. At the same time, many enthusiasts are also curious about the difference between the 01 and 02 drippers. We will provide an answer from the perspective of coffee bed depth and extraction uniformity, helping you understand the logic behind the parameters and brew more stable and delicious pour-over coffee.

Front Street Coffee uses a standard dose of 15 grams of coffee per serving, so when sharing brewing methods, 15 grams is always used as the demonstration standard. However, the dose used to brew coffee varies widely. Based on Front Street Coffee's observations, the most common doses are multiples of 6—12 grams, 18 grams, and 24 grams—and these are mostly used to make a single serving of 120 [more…]

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 incident also sparked heated discussion about Luckin's employee training, operating standards, and food safety. What exactly happened? Was the customer's complaint reasonable? And what problems did the store's operations expose? Let's take a look. [more…]

Walking into Front Street Coffee, the espresso machine is lined with ceramic cups of various capacities, each cup type corresponding to a specific coffee category. The size of a coffee cup not only affects the visual presentation but also directly influences the concentration expression and heat retention of the espresso. This article will systematically sort out the specific capacities and suitable scenarios of three coffee cup sizes—small, medium, and large: how a 60ml small cup carries a standard espresso, why a 180-200ml medium cup suits Americano and cappuccino, and how a 300ml large cup achieves a balanced latte. At the same time, combined with the extraction parameters of Front Street Coffee's Sunflower Warm Sun espresso blend coffee beans, it analyzes the pairing logic between different cup types and coffee flavors, helping you produce professional-grade coffee at home.

Walking into Front Street Coffee, ceramic cups of various sizes are neatly arranged on the espresso machine. These cups are not placed randomly but correspond to the serving needs of different coffees. The capacity of a coffee cup often hints at the intensity of the drink within—the smaller the cup, the more concentrated the coffee. A small cup holds about 60ml, used for espresso or as a sharing cup for pour-over; a medium cup holds 180-200ml, suitable for Americano and cappuccino; a large cup holds 300ml, the stage for milk coffees like latte and mocha. This article breaks down in detail the capacity, uses, and pairing logic of Front Street's three cup sizes, helping you choose the right cup at home and drink with professional standards. [more…]

Front Street Coffee's pour-over tutorials have long been based on a single-serving standard of 15g of coffee and 200ml of water, but when you need to brew 2 to 3 cups at once, the No. 01 small dripper simply can't handle the job. This article centers on a hands-on test of brewing with 30g of coffee in a V60 02 large dripper, starting with a 1:15 coffee-to-water ratio, 91℃ water temperature, and a three-pour technique, which revealed that the extraction time was too long and produced bitterness. The parameters were then revised by coarsening the grind and increasing the pouring speed, ultimately bringing the extraction time under 2 minutes 30 seconds, with the flavor matching that of a single serving. The article also retains recommendations for several Front Street Coffee beans and answers the question of whether the No. 01 dripper can brew a large dose when no No. 02 dripper is available, making it suitable as a reference for enthusiasts who have already mastered basic pour-over and want to advance to brewing for multiple people.

On a scorching summer day, iced drinks become the top sellers at beverage shops everywhere, yet the debate over "can you order it without ice" never dies down. A customer ordered an iced drink at Manner, noting that they only wanted two ice cubes, but after receiving it still found the temperature too low and asked the staff to remove the ice, only to be refused. The staff member helplessly explained that iced drinks must be made according to the standard ratio, and that removing ice without authorization would result in a pay deduction if caught on camera. Similar situations have occurred at Starbucks. Why are chain brands so "particular" about the amount of ice? And how should baristas choose between customer needs and company rules? This article will guide you through the industry logic behind the controversy over removing ice from iced drinks. [more…]

So when brewing with a dripper of the same size, [more…]

Starbucks has clearly picked up the pace of new product launches this year. Before people have even had a chance to check in on the cherry blossom limited edition, the Salted Flat White has already taken over as the store's main promotion. However, this new product has sparked controversy because of black powder residue left at the bottom of the cup, with many consumers suspecting that staff had made an operational error and mixed in coffee grounds. Faced with complaints, Starbucks staff collectively protested their innocence—having coffee powder is actually the correct method, and not having it would instead be a violation. What exactly is going on here? Why is the freshly ground coffee powder used for decoration so often mistaken for extraction residue? And why do consumers have so many complaints about the taste? This article will reconstruct the whole incident and analyze the gap between the standard recipe for this beverage and the consumer experience. [more…]
