In the grinding stage of pour-over coffee, the production of fines is almost unavoidable. These tiny particles, with a diameter of less than 0.1mm and a texture close to flour, are far off from the target particle size of 0.6~0.8mm. The source of fines is related both to the brittleness of the coffee beans themselves and directly affected by the quality of the grinder. For coffee enthusiasts, understanding the dual nature of fines—they can both improve extraction efficiency and enrich complexity, and may also bring bitterness and clogging—is the key to brewing the ideal flavor. This article will analyze the causes of fines, the differences between coarse and fine particles, and strategies for dealing with them during pour-over brewing, and provide reference in combination with the practical experience of Front Street Coffee.

When brewing pour-over coffee, if the filter basket ends up with a thick, muddy bed of grounds instead of distinct, granular particles, it often means the coffee was ground too fine, which easily leads to over-extraction. When faced with the dilemma of pre-ground coffee that cannot be made coarser, besides switching to immersion extraction, there is another distinctive approach using high concentration and low extraction—the mud flow. It uses extremely fine grinding combined with agitation to rapidly dissolve flavor compounds in a short time, then dilutes with hot water, resulting in coffee with a normal extraction yield and full flavor. In this article, Front Street will explain in detail the principles and specific operating parameters of the mud flow, helping you easily tackle the problem of coffee grounds that are too fine.

In espresso preparation, WDT needles are often used to break up clumps and stabilize extraction. But without professional tools, can a toothpick serve as a temporary substitute? Front Street Coffee took advantage of the humid weather of Guangzhou's returning south wind days and used the Warm Sun blend to conduct three sets of comparative extractions, observing the espresso performance with no WDT tool, with WDT needles, and after stirring with a toothpick, and further made iced americanos for a blind test. The results found that WDT needles can indeed make extraction more even, and toothpicks also have a certain effect under specific circumstances, but when paired with water or milk, the difference is not easily noticeable. This article will present the complete experimental process and conclusions, and explain the origin of WDT needles and the correct approach to using them. [more…]

Latte art is one of those things that can seem either difficult or easy—some people occasionally pour a beautiful pattern, but then can't reproduce it no matter how hard they try. At Front Street Coffee, we believe that judging the quality of latte art starts with whether the surface is smooth and fine, then whether the integration is even and the boundary between the golden ring and the pattern is clear, and only lastly comes the pattern itself—as long as the texture is sharp and the shape is well defined, that's enough. Theory can't replace feel, but a few small tips can help you reduce your failure rate. This article walks you through bean selection, milk foam thickness, pre-fusion preparation, repeated practice of basic patterns, and flexible adaptation, teaching you step by step how to make stable, attractive latte art with hot fresh milk.

Today, a coffee cup and saucer are mostly just a coaster and a decorative item. But in Europe before the eighteenth century, the saucer was the "star" of coffee drinking. In 1640, the Dutch brought coffee from Mocha in Yemen to the Netherlands, and from there it spread throughout Europe, quickly making coffee drinking a fashion among the upper classes. At that time, Europe had not yet mastered porcelain-making technology and could only import thin, light porcelain cups from China—yet these cups had no handles, making the freshly brewed coffee too hot to hold. So people poured the coffee into the saucer to cool it, then sipped it the way modern cuppers do. It was not until the eighteenth century, when the Germans mastered porcelain production and handled porcelain cups became widespread, that the habit of drinking coffee from the saucer gradually faded away. This history has also been recorded in many paintings, so let's look together at the coffee stories in those still lifes and figure paintings. [more…]
