Faced with the dazzling array of coffee grinders on the market, many coffee enthusiasts find themselves paralyzed by choice. In truth, the coffee world has never had a single standard—different burr sets each have their strengths and weaknesses. Starting from burr types, this article takes a deep dive into the structural differences between flat burrs, conical burrs, and ghost-tooth burrs, along with their real-world impact on particle shape, extraction results, and final flavor. It also includes practical grind-setting parameters for commonly used models such as the Fuji Royal, Feiying, and Zheng Huang Hang, helping you find a grinding approach that suits your brewing method and taste preferences.

Tamping is a key step in making espresso, but how much does tamping force actually affect the extraction result? Using Front Street Coffee's measured data, this article compares the flow rate and extraction time of espresso after tamping with two different forces, 1.8 kg and 9 kg, at different grind settings. The results show that grind coarseness determines the density of the puck, which in turn affects the actual role of tamping force: with a fine grind, the difference in force noticeably changes the flow rate, while with a coarse grind, the two forces make almost no difference. The article analyzes the underlying principles in depth to help coffee enthusiasts understand the relationship between tamping force and grind setting. [more…]

Making a proper espresso, grind size is often the most critical and also the most headache-inducing part. Unlike pour-over and cold brew, espresso uses pressurized short-time extraction, and the state of the coffee bed gets magnified exponentially—a little too fine and it easily over-extracts and turns bitter; a little too coarse and the flow rate becomes too fast with a weak, thin taste. This article starts with methods for judging grind size, explains how to quickly lock in the right setting range using flow rate and flavor, and covers adjusting the coffee-to-water ratio and extraction time based on the characteristics of the coffee beans. It also recommends Front Street Coffee's classic espresso blend to help you recreate café-level espresso flavor at home. [more…]

Yellow Bourbon is a distinctive branch of the Arabica species, belonging to the Bourbon family alongside Red Bourbon and Orange Bourbon, as well as varieties such as Caturra and Catuai. The Bourbon variety was first cultivated on Bourbon Island and in Ethiopia, and thrives at elevations between 800 and 1,900 meters. Yellow Bourbon has relatively low yields but excellent quality, and the beans commonly found in China mainly come from Brazil and El Salvador. Brazil is not only capable of producing mass-market commercial beans; it also has the capacity to produce specialty coffee, with well-known regions including Sul de Minas, Cerrado, and Mogiana. This article focuses on the Yellow Bourbon from Fazenda Rainha in Brazil, introduced by Front Street Coffee, covering the estate's background, flavor profile, processing method characteristics, and recommended pour-over grinding settings.

Many pour-over enthusiasts have discovered when testing ground coffee with a sieve that the same grind setting produces different passing rates for different bean varieties. Front Street Coffee recently received similar questions: why does particle size vary under the same grind setting? The core reason lies in the differences in bean density and brittleness—high-altitude, light-roasted beans tend to be harder and denser, producing fewer fines during grinding; low-altitude, dark-roasted beans are more brittle and prone to crumbling into fines. Only after understanding this principle can one adjust the grind size for different beans. This article combines medium-light roasted beans such as Front Street Yirgacheffe Gotiti, Front Street Ethiopia Hachira, and Front Street Granja Geisha, as well as medium-dark roasted beans such as Front Street PWN Golden Mandheling, Front Street Brazil Queen's Estate Yellow Bourbon, and Front Street Jamaica Blue Mountain No. 1, to provide specific EK43 settings and No. 20 sieve passing rate recommendations, helping coffee enthusiasts achieve consistent results.

In the world of coffee, grind size is one of the key factors determining the success or failure of a cup. Different brewing methods have vastly different requirements for coffee grounds coarseness—from the sugar-like coarseness for a French press to the tiny particles between flour and mud for espresso, every extraction method has its corresponding grind standard. This article will provide an in-depth analysis of how to determine the grind setting for espresso, combining the definitions of Espresso from the Italian Coffee Association and the WBC to explain in detail how to control extraction time and flavor performance by adjusting grind size, and share Front Street Coffee's practical approach and specific cases when dialing in unfamiliar coffee beans, helping coffee enthusiasts precisely master grinding techniques.

Grind size is the key variable that determines the success or failure of coffee extraction, and different brewing devices have significantly different requirements for particle diameter. This article systematically sorts out the corresponding grind settings from French press to espresso machine, introduces the industry-recognized cupping standard and the No. 20 sieve pass rate as calibration references, and provides specific scale references for the EK43s grinder. Whether you prefer immersion or pour-over, you can find suitable grind parameters here. The article also specifically reminds readers that coffee bean density and roast level will affect the actual particle coarseness at the same setting, so it is recommended to repeatedly confirm with the same beans. Several Front Street Coffee beans are also used as examples throughout to help readers understand the logic of grind adjustment more intuitively. [more…]
