Have you ever heard the word "Body" from a barista or a fellow coffee enthusiast? It refers to the sense of volume and richness that coffee presents in the mouth, and it belongs to the tactile level of experience. Many people confuse Body with strength, but what truly determines richness is the oils and fibrous materials in coffee that do not dissolve in water. This article will start from the definition of Body, clarify the difference between it and mouthfeel and smoothness, and share a brewing method recommended by Front Street Coffee—by lowering the water temperature, reducing agitation, and extending the steeping time, pour-over coffee can also present a smooth and full-bodied texture.

The Golden Cup extraction is a concept often mentioned in coffee circles. It uses two indicators—concentration and extraction yield—to judge whether a cup of coffee has been properly extracted. This theory can be traced back to 1952, when it was developed through collaborative research by the American coffee association and Dr. Lockhart of MIT. After multiple revisions, the Golden Cup range currently recognized by the SCAA is: extraction yield 18%-22%, concentration 1.15%-1.35%. But the Golden Cup numbers are only a reference tool, not an absolute formula for brewing delicious coffee. This article will walk you through the origins and development of Golden Cup extraction, the meaning of concentration and extraction yield, how to calculate extraction yield using formulas, and why you should not be limited by the Golden Cup range.

The charm of pour-over coffee lies in extracting rich flavors from coffee grounds with a simple pouring action. This article starts with the function of the dripper, first explaining why blooming is important—too much water will dissolve off-flavors and astringency along with it, while too little water will lead to insufficient extraction. Then, using Kenya Asali beans as an example, with a grind size of BG 5M, water temperature of 91°C, a coffee-to-water ratio of 1:13, and pre-infusion of 40-45ml/30-35 seconds, it compares in detail two common techniques: the continuous-pour method, which uses a steady thin stream to draw circles from the inside outward and finishes in about two minutes, yielding balanced acidity and sweetness with a long caramel finish, but a slightly flat body and flavor; and the pulse-pour method, which pours in stages, using large and small streams for the first two pours to agitate the coffee grounds and increase acidity and sweetness extraction, then switching to a submerged, non-agitating final pour to avoid pronounced bitterness, bringing the flavor up from raisin to blackcurrant juice, though with a shorter and weaker aftertaste. The article also includes relevant recommendations from Front Street Coffee, suitable for coffee enthusiasts to refer to. [more…]

After light-roasted coffee beans leave the roaster, subtle gas exchange continues inside them.

What exactly is the relationship between the coffee fruit and the coffee bean? A coffee cherry, from the outside in, consists of multiple parts including the exocarp, pulp, pectin layer, parchment, silver skin, bean core, and center line, with each layer playing a different role in coffee processing and flavor formation. The green coffee bean itself is composed of substances such as water, polysaccharides, lipids, proteins, sucrose, chlorogenic acid, other organic acids, amino acids, and caffeine, all of which directly affect coffee's mouthfeel, aroma, and the balance between bitterness and acidity. This article will dissect the structure of the coffee fruit layer by layer and systematically sort out the compositional substances of coffee beans, while also explaining the difference in caffeine content between Arabica and Robusta, helping coffee enthusiasts gain a more comprehensive understanding of the science behind the flavors in their cup.

The Golden Cup extraction is a widely circulated concept in the coffee world, defining an extraction range that most people find acceptable. This concept originated from a large-scale preference survey in the United States in the 20th century, promoted by the Brewing Committee established by the American Coffee Association in collaboration with Dr. Lockhart of the Massachusetts Institute of Technology. The survey found that about 30% of coffee beans are soluble substances, while the remaining 70% are insoluble fibers. After two rounds of testing with ordinary people and coffee experts, the Golden Cup range was ultimately determined as an extraction yield of 18% to 22% and a concentration of 1.15% to 1.35%. This article will sort out the origins and development of the Golden Cup standard, the calculation methods for extraction yield and concentration, and explain why the Golden Cup range can only serve as a reference rather than an absolute standard, helping you view coffee extraction more rationally. [more…]

How exactly should the extraction yield and strength of pour-over coffee be calculated? The golden cup extraction yield range defined by the SCAA is 18% to 22%, corresponding to a TDS strength of about 1.15% to 1.35%, while the coffee-to-water ratio falls within the range of 1:12 to 1:15. This theory originates from Dr. Lockhart's scientific experiments in the 1950s, in which he quantified coffee flavor and laid the foundation for the golden cup standard. This article starts from the daily brewing at Front Street Coffee, explains the definitions of extraction yield and strength, the conversion formulas, and how to use a refractometer, and, using beans from Panama's Elida Estate as an example, fully demonstrates the parameter settings, pouring rhythm, and extraction yield calculation process of a staged pour-over, helping coffee enthusiasts understand the practical application and reference value of the golden cup theory.
