When using an espresso machine to extract espresso, many people have encountered the situation where the puck sticks firmly to the brew head. Once the puck falls off, it not only tends to crumble into the drip tray, but is also quite troublesome to clean up. Some people therefore believe that the coffee's flavor will become worse, but is that really the case? Front Street, based on an actual encounter, tasted the coffee extracted while the puck was stuck and analyzed the various operational factors that lead to this phenomenon, including the dose, the timing of removing the portafilter, and bumping before extraction, to help everyone more clearly understand the real reasons why the puck sticks to the brew head.

What water temperature is actually suitable for pour-over coffee? Does a higher temperature always mean better extraction? Starting from everyday dissolution phenomena, this article explains how water temperature affects coffee extraction efficiency, and uses cupping immersion experiments and pour-over comparison data to show how coffee flavor actually performs at different temperatures. The article also explores competition brewers' high-temperature brewing strategies, and why Front Street Coffee recommends a relatively narrow brewing temperature range, helping enthusiasts understand the key role of water temperature in brewing and avoid common misconceptions.

Water temperature is a key variable in controlling the pace of coffee extraction. Most brewing guides set the recommended range at 86–93°C, and very few people dare to use water below 80°C or above 95°C on coffee. So what happens if you boil water and brew with it directly? This time, Front Street Coffee selected a medium-light roast Colombia·Frontera Big Navel and a medium-dark roast Indonesia·Mandheling, using conventional temperature and boiling water for comparison, and compared concentration, aroma, and mouthfeel item by item. The article not only provides two sets of measured data, but also explains how temperature affects the release of sourness and bitterness, as well as the suitable water temperature ranges for light roasts and dark roasts respectively, helping you understand whether 92°C is really a hard standard that must be followed.

Blooming is an almost indispensable step in pour-over coffee. Typically, we pour a small amount of hot water to wet the coffee bed, then wait for about 30 seconds.

Front Street conducted comparative brewing experiments with three coffee beans of different freshness levels, measuring the extraction yield difference between a 30-second and 60-second bloom, explained the mechanism of blooming from the perspective of carbon dioxide release, and offered blooming time recommendations suitable for beginners.

When making espresso, the choice of portafilter is often overlooked, yet it directly affects the consistency of the output and the operating experience. A split portafilter has a closed bottom with two spouts, allowing it to evenly distribute a double shot of espresso; a bottomless portafilter removes the bottom cover, making it easier to observe the extraction state, and is especially advantageous for identifying channeling and making layered coffee. However, the two also differ noticeably in flow rate, preheating requirements, and cleaning and maintenance. This article will systematically compare the features of split portafilters and bottomless portafilters, and offer practical advice from Front Street Coffee to help you make a more suitable choice in your daily output.

Catimor is not a single variety, but rather a group of varieties with similar bloodlines, and its birth stemmed from humanity's efforts to combat coffee leaf rust. From the natural hybrid Timor Hybrid found on the island of East Timor to its combination with Caturra, Catimor inherited the flavor potential of Arabica and the disease-resistant genes of Robusta. This variety group is widely cultivated in the Americas and Asia, especially in Yunnan, China, where Catimor replaced the traditional Typica and became the main variety.

A post about a Luckin Coffee service experience recently sparked discussion on social media. The poster said that while organizing an office event, they ordered 60 drinks from a local Luckin store. When picking up the order, they found the coffee had not been packed into boxes and had to carry it to the car bag by bag, while the staff did not offer help on the grounds that they could not leave the store entrance. The customer also complained that the entire order had no discount and said that even if they ordered 600 cups next time, they would not choose this store again. However, most netizens sided with the staff, arguing that chain coffee stores do not normally offer group-meal discounts, and that Luckin has strict requirements for food safety and operating procedures, making it difficult for employees to leave their posts to help with carrying during peak hours.
