Every coffee cherry is like a miniature flavor factory, with six layers—from the outermost skin to the seed buried deep within—each playing its own role. It is precisely the existence of these layers and the differences in how they are removed that determine the flavor directions of different processing methods such as natural, washed, and honey. The coffee tree belongs to the Rubiaceae family as an evergreen shrub or small tree, and its fruit is called a coffee cherry in the industry because its shape closely resembles a cherry. This time, we will not discuss the legend of the shepherd, nor repeat the classification of the three major varieties; instead, we will focus on the internal structure of the coffee cherry, disassembling one by one the six layers—exocarp, pulp, mucilage layer, endocarp, silver skin, and endosperm—to see how they work together to give coffee its ever-changing flavor expression.

The annual global production of coffee beans reaches as high as 8.4 billion kilograms, and what influences the final flavor of a cup of coffee, besides variety, origin, and cultivation methods, is another crucial step—the processing method. Front Street Coffee believes that different processing methods lead to entirely different flavor directions. This article will provide an in-depth analysis of the complete process and characteristics of the washed processing method, starting from the anatomical structure of the coffee fruit, gradually breaking down each step of the washed method, and comparing the core differences with the natural method. At the same time, Front Street Coffee uses two washed beans, Kenya Asaliya and Yirgacheffe Gudingding, as examples, and through actual brewing experiments, demonstrates the flavor changes brought by different origins and varieties under the same processing method, helping coffee enthusiasts build a clearer framework for taste perception.

Besides the bean inside the coffee cherry that can release thousands of aromatic compounds after roasting, the peeled fruit skin can actually also be brewed and drunk. In Europe and America it is called Cascara, while in China it is often called coffee cherry tea. This article begins with the tissue structure of the fruit skin, the materials removed during green bean processing, and the old uses of the skin as fertilizer or waste, then traces back to the story of Salvadoran estate owner Aida Batlle, who accidentally discovered its sweet aroma after sun-drying and tried brewing it, explaining that Cascara in Spanish simply means skin and husk. It then introduces the production process of the skin, from peeling, sun-drying, and manually removing impurities to 4–5 days of drying and color-change monitoring, analyzes the flavor characteristics of the skin tea, which is almost only sweet, and provides Front Street Coffee’s practical reference for hot brewing at 94°C water temperature, 20g of skin with 400ml of water, and a 1:20 ratio, as well as key points such as cold brew and specialty drinks, and caffeine being only one quarter that of coffee.

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.

Pour-over coffee may seem complicated, but there is actually a low-effort yet stable extraction method—the single-pour center pour. It doesn't require segmented circling; simply keep pouring continuously after the bloom, making it especially suitable for those new to pour-over. This article uses the Yirgacheffe Red Honey Red Cherry recommended by Front Street Coffee as an example, first introducing the classification of honey processing and the proportion of pectin retained, then using the Hario V60 dripper to conduct a comparative brewing of two different grind sizes: a coarse grind BG-7K paired with a longer pouring time, and a fine grind BG-6M paired with a shorter pouring time, to experience the flavor differences under the same coffee-to-water ratio and water temperature. The article also explains in detail how the V60's rib structure affects flow rate, and why pouring stability is far more important than fancy techniques. [more…]

In the realm of immersion extraction, the French press and the Clever Dripper are two devices often compared to each other. They both use immersion, yet the final coffee flavor heads in completely different directions. Starting from Front Street Coffee's comparative experiment, this article first introduces the structure and operating principles of the two devices separately, then distinguishes them across dimensions such as material, shape, and pouring method, and finally takes [Front Street Sun-Dried Red Cherry] as an example, brewing separately under the same water temperature, grind size, and coffee-to-water ratio to explore where the French press's rich smoothness and the Clever Dripper's clean clarity actually come from, and what role oils and filter paper play in this, helping coffee lovers make a choice according to their taste preferences.

Freshly roasted coffee beans are rich in carbon dioxide internally. Under the heat of a medium roast, a loose, porous structure forms, and these gases are gradually released over the following days. If you grind and brew the beans immediately after getting them, the vigorous bubbling of gas will hinder full contact between the water and the coffee grounds, leading to uneven extraction. [more…]

From the branch to the cup, coffee cherries must undergo a series of processing steps, and the different processing methods directly determine the flavor profile of the final coffee beans. The four traditional processing methods—natural, washed, semi-washed, and honey—each exhibit distinctly different characteristics in terms of cost, acidity, sweetness, body, and cleanliness. Starting from the structure of the coffee cherry, this article will break down the complete process, advantages, and disadvantages of each processing method one by one, and pair them with specific bean recommendations from the Front Street Coffee brand, helping coffee enthusiasts build a clear framework for understanding flavor and find the one that best suits their taste in everyday pour-over choices.

The Clever Dripper combines the immersion advantages of a French press with the clean mouthfeel of a pour-over dripper, featuring a low barrier to entry and the ability to produce a decent cup of coffee in just two minutes. Its central movable piston automatically seals when lifted off the container; when placed on a sharing carafe, the valve is pushed open, allowing the coffee to flow down. This adds an immersion extraction step compared to ordinary drippers, and the pouring technique has much less impact on the result. What truly determines the flavor are still the variables of water temperature, coffee-to-water ratio, grind size, and immersion time. This article focuses on the working principle of the Clever Dripper, recommendations for grind and water temperature, and an immersion demonstration at the Front Street Coffee shop using the Yirgacheffe Natural Red Cherry Project, outlining a stable brewing approach suitable for beginners, along with reference parameters for light-roast and dark-roast beans.
