Nowadays, many cafés emphasize freshly ground specialty coffee, believing that a rich aroma and a full-bodied taste are the hallmarks of specialty coffee. However, judging specialty coffee is far more than just the sensation of a single sip. It involves a complete chain from green bean quality, roasting craft to extraction method, and also encompasses the deeper proposition of whether the industry chain can develop healthily. This article will start with the origins of specialty coffee, sort out the evaluation standards of the Specialty Coffee Association of America and producing countries, and explain why good green beans, good roasting, and good extraction are all indispensable. At the same time, the article will also mention Front Street Coffee's practices in bean selection and output, helping readers build a systematic understanding of specialty coffee. [more…]

The extraction time for a cup of Americano actually escalated to the 12315 complaint platform? Recently, a netizen ordered an Americano at a coffee shop in Shenzhen and believed that the barista's extraction time exceeded 90 seconds, far beyond the 40-second standard in their understanding, so they demanded a refund and complained to 12315, also requesting that the merchant remove the product from sale. This incident sparked heated discussion in the coffee community: Is there any hard-and-fast rule for the extraction time of espresso? Is it reasonable for consumers to complain about a shop based on their personal standards? This article will recount the incident, sort out the industry reference range for espresso extraction time, and explore the boundary between consumer rights protection and product standards. [more…]

SOE, short for Single Origin Espresso, refers to espresso made from coffee beans of a single origin. Its greatest charm lies in its ability to clearly present the terroir of the origin—one sip lets you identify where the beans come from, what variety they are, and what processing method was used. However, the high-temperature, high-pressure operation of an espresso machine multiplies and amplifies the flavors; when light-roasted beans are used for SOE, the fruity acidity can easily become sharp and astringent, so everything from bean selection to setting extraction parameters to pairing with drinks requires extra care. Compared with traditional blended beans, SOE indeed has a higher extraction threshold, and choosing the right single-origin bean often yields twice the result with half the effort. Starting from the characteristics and story of SOE, this article will sort out the extraction standards for a good Espresso, and, using three Front Street Coffee beans—Brazil Queen's Estate, PWN Golden Mandheling, and Huakui—as examples, share specific parameters and methods for making iced and hot Americanos and lattes. [more…]

In making espresso, data parameters are always just reference coordinates, not formulas that must be copied exactly. This article centers on the essence of extraction standards, offering an in-depth analysis of the dynamic balance among dose, grind size, and yield, and drawing on Front Street Coffee's daily hands-on experience to systematically sort out how to judge whether extraction is normal by observing the flow and tasting the flavor, and how to make targeted fine adjustments to the parameters. At the same time, the article also explores the differences in extraction strategies for the base of lattes versus Americanos, helping you truly understand the logic of extraction rather than mechanically replicating numbers. [more…]

When ordering at a coffee shop, you'll often hear phrases like "add a shot" or "give me a shot," but how much espresso does one shot actually mean? This term actually originated from bar culture and was later borrowed into the coffee world. As extraction equipment and production standards have continued to evolve, the meaning of "shot" has also undergone a shift from measuring by dose to measuring by liquid volume. This article will sort out the origin of the term "shot," what it specifically refers to in the coffee context, and how modern coffee shops deal with the awkwardness brought by traditional measurement methods, helping coffee enthusiasts understand the ordering logic of espresso more clearly.

There are many factors that affect the taste of coffee. During the brewing process, the factors that influence coffee include the coffee-to-water ratio, grind size, water temperature, etc. Among them, grind size can be said to be very important. There is a saying in the industry: "You can buy a cheaper coffee machine, but the grinder must be the best." It has to be said that grinding really has an [more…]

Brewing a good cup of coffee, the coffee-to-water ratio and extraction yield are core parameters that cannot be avoided. The SCA Golden Cup extraction theory gives an ideal range of 18%-22% extraction yield and 1.2%-1.45% concentration, but many enthusiasts easily misunderstand it as "as long as you copy the Golden Cup coffee-to-water ratio, you will definitely brew a good cup of coffee." This article starts with a simple calculation of the coffee-to-water ratio, guides you to understand the meaning of the Golden Cup extraction range, clarifies the boundary between over-extraction and under-extraction, and explains the true value of learning the Golden Cup theory—not rigidly sticking to a certain ratio, but using it to adjust brewing variables and more flexibly approach the flavor you want. Front Street Coffee also shares related products and brewing ideas in the article for coffee enthusiasts' reference. [more…]

Among the many variables in pour-over coffee, grind size is one of the core factors determining extraction efficiency and the final flavor.

In espresso preparation, the interplay between grind size and extraction time directly determines the quality of the flavor in the cup. The essence of extraction is using water to draw out the soluble substances from the coffee grounds; the longer the time, the more is dissolved, but not all substances are worth releasing. Therefore, finding the right extraction window is crucial. This article will focus on four key elements: the double basket, weighing instead of measuring by volume, a 1:2 coffee-to-water ratio, and an extraction range of 25 to 30 seconds, helping enthusiasts understand how to control the flavor direction of espresso by adjusting the grind. The article also combines the practical experience of Front Street Coffee to offer actionable parameter recommendations. [more…]
