The milk foam on the surface of a latte sometimes sinks and collapses, sometimes becomes stiff and separates into layers, and sometimes visibly breaks down within just two minutes, with even faint popping sounds of bubbles bursting audible. Behind these phenomena lie multiple factors, including the thickness of the steamed milk foam, the stability of the espresso crema, the extraction state, and even the cleanliness of the cup. Front Street will analyze one by one the causes of common problems such as sunken foam, severe layering, surface collapse, and large bubbles forming on the cup wall, helping you understand the supporting relationship between milk foam and crema, so that you can make a latte with delicate, silky foam and long-lasting latte art.

The blooming phase of pour-over coffee is often seen as the first dialogue with the coffee grounds, and an ideal expansion state often indicates a smooth subsequent extraction. However, sometimes the coffee bed clearly puffs up, only to have a pit form in the middle moments later—is this actually normal?

Front Street Coffee uses 15 grams of light-roast beans for simulation comparisons, showing the actual changes in the coffee bed under different parameters, to help you quickly identify problems in daily brewing, adjust your technique and parameters, and get the blooming state back on track.

Taking photos at coffee shops has long become a daily routine for many customers, but accidents caused by this practice happen from time to time. A coffee shop owner recently encountered an exasperating yet almost comical scene: two young women entered the restroom while taking photos in the shop, and shortly after, a loud crash was heard. After the two hurriedly left, the owner discovered that the entire washbasin had broken off and crashed to the floor. Surveillance footage showed the two had entered the restroom to take photos, but that area happened to be a blind spot in the camera coverage, making it impossible to confirm what had happened. Netizens speculated that a customer may have sat on the wall-mounted washbasin, causing it to give way under the weight. The incident sparked widespread discussion, with many expressing sympathy for the owner, while others suggested relocating the washbasin or posting a notice to prevent similar situations from happening again.

This article will analyze the causes of "expanding first, then sinking" from three angles—water volume, grind size, and pouring technique—and, combined with Front Street Coffee's brewing experience, provide specific judgment and adjustment suggestions to help you master the blooming stage more precisely.

Recently, a customer encountered an bizarre scene at a Starbucks store: while waiting in line to use the restroom, they suddenly heard a loud noise, and then a man hurriedly fled from the bathroom. Upon entering, they discovered that the toilet had been cracked by being stepped on and had separated from the sewage pipe, shifting more than ten centimeters. This bizarre incident quickly sparked heated discussions among netizens and unexpectedly brought up the topic of Starbucks restrooms gradually disappearing. Many netizens were surprised that Starbucks actually had restrooms, while longtime customers recalled that in earlier years, most stores had restrooms open to the public, but this convenience measure brought endless troubles for employees—filth and disorder, long-term occupation, and even people showering or washing vegetables inside. Now, new Starbucks stores are gradually no longer including restrooms, and older stores often lock them, citing malfunctions. This article takes you through the whole incident and the helpless reality behind it. [more…]

During a pour-over bloom, the coffee bed swelling into a rounded "hamburger" dome is an important visual signal for many enthusiasts to judge the state of the beans and whether the brew is on track. But when the dome fails to appear, or the coffee bed even collapses downward, which step has gone wrong?

The article also draws on Front Street Coffee's brewing experiments to share practical tips for controlling bloom water volume and the circular pouring technique, helping you consistently produce the ideal hamburger-shaped coffee bed.

The milk foam on the surface of a latte begins to break down the moment espresso extraction is complete and milk steaming ends, and the key indicator of its stability is the rate of foam dissipation. By normal standards, a latte made by Front Street Coffee will only show visible, obvious foam dissipation after sitting for about ten minutes. However, if a freshly made latte collapses, curdles, or turns into large bubbles within two minutes, something is wrong, and the causes need to be checked one by one. This article analyzes the reasons for rapid milk foam breakdown from five aspects—crema and foam coarseness, foam thickness, coffee bean freshness, number of pitcher taps, and evenness of integration—and provides the corresponding solutions that Front Street Coffee has summarized through actual practice.

After pour-over brewing is finished, the coffee bed in the dripper often takes on different shapes—some people can produce a beautiful, even deep pit, while others end up with a flat bed or even a muddy crater. What exactly are these coffee bed shapes telling us? In fact, the appearance of the coffee bed mainly reflects information about the pouring method and the coffee grounds themselves, and has no direct correlation with whether the coffee tastes good. Front Street will start with six common coffee bed states, interpreting one by one the causes and meanings of the deep pit, the offset pit, the flat bed with a grounds wall, the flat bed without a grounds wall, the fractured bed, and the muddy pit, to help you better judge whether your pouring is appropriate in daily brewing and make timely adjustments.

Vietnam's core coffee-producing region—Kon Plong District in Kon Tum Province—recorded 32 earthquakes within just 24 hours, the strongest reaching magnitude 5.0, triggering tremors across the Central Highlands, several surrounding provinces, and even parts of Thailand. Experts say the quakes are linked to reservoir-induced activity and may continue in the future. As a key part of Vietnam's Central Highlands coffee belt, Kon Tum Province and neighboring provinces account for about 70% of the country's robusta coffee output. The earthquakes could cause farmland subsidence, fluctuations in groundwater levels, and shortages of irrigation water. Combined with this year's severe drought and shrinking cultivation area, the risk of a decline in Vietnam's coffee production is further intensifying. Front Street Coffee will continue to monitor developments in the producing region and their impact on the coffee market. [more…]
