Previously, when Front Street shared knowledge related to espresso extraction, it would focus on the effects of parameters such as dose, ratio, grind, time, and pressure on extraction. In addition, it also emphasized analyzing the key operational points in steps such as receiving the grounds, distributing the grounds, tamping, and locking the portafilter into place. Only water temperature was something Front Street always [more…]

Many people assume that pour-over coffee can only be made with a gooseneck kettle and a dripper, but in fact, an espresso machine can also produce a satisfying cup of drip coffee. The key lies in the proper setting of brewing parameters, not the pouring method itself. Using Front Street Ethiopia Huakui as an example, this article explains in detail the entire process of making pour-over coffee with an espresso machine, including water temperature measurement, dripper selection, grind size adjustment, and the specific steps of pulse pouring. It also explores the so-called fake pour-over concept, helping readers understand the core logic of coffee extraction and allowing home espresso machines to unlock more possibilities. [more…]

When extracting espresso, parameters like grind size, dose, ratio, time, and pressure are often discussed repeatedly, but water temperature is often overlooked. In fact, water temperature has a decisive influence on the flavor direction of espresso—too high brings burnt bitterness and woody notes, while too low makes the coffee sour and astringent with thin crema. Starting from Front Street's practice, this article systematically sorts out the reasonable range for coffee machine water temperature, how water temperature affects flow rate, the difference between boiler temperature and actual extraction temperature, and how to set water temperature under different dose ratios, helping you find that delicious temperature point in your daily shots.

A cup of SOE can showcase the floral and fruity acidity of a light roast, the caramel sweetness of a medium roast, or even the cocoa notes and heavy body of a dark roast. Home espresso machines are not only suitable for blends—as long as the machine can heat stably, build pressure, and is equipped with a suitable single-shot basket, it can pull single-origin espresso. What truly matters [more…]

Many coffee enthusiasts will notice that with the same beans and the same machine, the flow rate of espresso can change every few hours or even every few dozen minutes, sometimes fast and sometimes slow. Beyond the aging characteristics of the coffee beans themselves, there are actually quite a few easily overlooked hidden factors influencing the extraction results, including residual grounds in the grinder's chute, temperature fluctuations in the espresso machine's hot water, the state of the pump pressure, changes in ambient temperature, humidity and air pressure, and whether the grinder's hopper pressure remains stable in a café setting. Front Street will analyze these factors' mechanisms of influence on espresso extraction one by one, and provide corresponding improvement solutions to help everyone reduce unnecessary adjustments and make their output more consistent. [more…]

There are countless pour-over coffee brewing methods, but the core variables that truly determine flavor are simply grind size, water temperature, and the coffee-to-water ratio. Yet these seemingly simple parameters and circular pouring make it hard for many people to consistently reproduce a good cup of coffee. Machines are naturally superior to humans in consistency—does this mean baristas will eventually lose their jobs? Front Street has a bold prediction: mechanized production roles may be replaced, but baristas who truly understand brewing logic will move behind the scenes, responsible for formulating and adjusting plans. This article starts from standard brewing methods and explores the relationship between technique, understanding, and the future of baristas. [more…]

When pulling espresso, what temperature should the water actually be set to? Starting from Front Street's hands-on experience, this article systematically sorts out the specific effects of water temperature on extraction efficiency, the flow rate of the coffee liquid, and the richness of the crema, and combines the differences in dose and ratio between espresso and Americano to explain why the preferred water temperature ranges for the two are not the same. The article also introduces a practical approach: fix the water temperature within a reasonable range, and instead adapt by adjusting the grind and liquid weight, so as to quickly and stably extract a delicious espresso. In addition, the article also gives specific explanations on the deviation between boiler water temperature and actual extraction water temperature, as well as how to respond when the interval between extractions is too long.

As China's specialty coffee wave continues to heat up, espresso is practically a standard offering in every café, yet its offshoot, Americano, leaves many people puzzled: what exactly is the difference between the two? This article, from the perspective of Front Street Coffee, first introduces you to the extraction logic of semi-automatic espresso machines and espresso, traces the history from the first coffee machine in 1884 to the Faema E61, then breaks down key parameters one by one—dose, brew ratio, time, pressure, water temperature—and introduces the flavor profiles of several Front Street Coffee espresso blends, finally explaining how espresso becomes a cup of Americano when diluted with water.

Cold brew coffee typically requires a steeping time of more than 8 hours, followed by a period of maturation to reveal its full flavor. But many coffee enthusiasts want to shorten the waiting time, so some bloggers have shared a method for "making high-sweetness cold brew in one minute"—using a hand press or espresso machine to extract with cold water at 9 bar of pressure. Front Street Coffee has also experimented with ice-water extraction, and the result was a cup of cold brew that looked decent in just a few minutes, but tasted like little more than coffee-flavored water, with a mouthfeel and strength far inferior to the long-steeped version. This article analyzes in detail the principles and limitations of rapid cold brew, explains why flavor compounds cannot be fully dissolved at low temperatures even under pressure, and offers a more feasible way to shorten the time: appropriately raising the initial steeping water temperature. It also answers common questions such as how long cold brew coffee can be stored. [more…]

As technology continues to advance, coffee brewing has entered the era of automation. Automatic milk frothing and automatic latte art have long been commonplace, so can the ritual-rich pour-over coffee also be entrusted to a machine? This article, through a comparative experiment between an automatic brewing coffee machine and manual pour-over, uses the same Front Street Golden Mandheling, comparing grind size, coffee-to-water ratio, water temperature, and brewing technique one by one. The experiment not only tested whether the extraction yield fell within the golden cup range, but also conducted tasting from dimensions such as flavor layering and body thickness. At the same time, the article also provides suggestions for coffee beans suitable for pairing with automatic pour-over coffee machines, covering different roast levels and flavor orientations, helping enthusiasts choose equipment and beans more rationally.
