When grinding coffee beans, you'll often notice yellowish-white flecks mixed into the grounds—this is silver skin, the last protective layer of the green bean. How much of it remains depends mainly on how the coffee was processed, not on roasting technique. Natural-process beans shed their silver skin more completely, while washed beans, because the silver skin breaks into fragments, leave white lines in the bean's crease. Many people worry that silver skin will ruin the flavor. Through tasting silver skin steeped in water and comparative brewing experiments, Front Street found that silver skin itself carries a sweet corn- and wheat-like sweetness, and that coffee brewed without removing the silver skin tastes basically the same as coffee with it removed. This article will explain in detail where silver skin comes from, how it differs by processing method, and whether it truly affects coffee flavor. [more…]

When buying coffee beans, the packaging often indicates processing methods such as natural, washed, and honey. What exactly is the difference between natural and washed? Front Street Coffee takes you through the structure of the coffee fruit to explain in detail the specific steps, advantages and disadvantages, and flavor characteristics of the two processing methods. It also uses two Yirgacheffe coffees—Front Street Natural Red Cherry and Washed Gudingding—to compare the silver skin differences between green beans and roasted beans, and to analyze the fermented sweetness of natural beans and the bright cleanliness of washed beans. Only by understanding processing methods can you better choose the flavor you love. [more…]

Many pour-over enthusiasts, after grinding coffee beans, feel uneasy when they notice silver skin remaining in the grounds—will these white flecks bring astringency and ruin a cup's cleanliness?

Faced with a dazzling array of coffee beans, how can you quickly tell whether they are sun-dried or washed? In fact, as long as you grasp the basic processes of the two processing methods, and then combine them with the color of green beans, the silver skin of roasted beans, and the performance in the cup, you can easily distinguish them. The sun-dried method has a long history and relies on natural drying, so sugars easily seep into the bean surface; the washed method uses water tank screening and soaking to give coffee a cleaner tone. This article will start from the processing steps and compare one by one the differences between sun-dried and washed in green beans, roasted beans, and flavor, and use Front Street Yirgacheffe Sun-Dried Red Cherry and Washed Gudingding as examples to provide specific brewing comparisons, helping you quickly establish a basis for judgment in daily tasting.

Everyone's demand for coffee is growing stronger by the day, with global coffee bean production reaching as high as 8.4 billion kilograms annually—an astonishing output. When it comes to coffee, Front Street believes that beyond variety, origin, and cultivation methods, there is another important process that influences coffee flavor: coffee bean processing methods. Different processing methods for coffee beans [more…]

Among coffee bean processing methods, natural and washed are the most common, and the two differ significantly in green bean appearance, roasting performance, silver skin shedding, and final cupping flavor. Through long-term cupping, Front Street Coffee has found that washed beans highlight the bean's intrinsic flavor, with bright and clean acidity; natural beans, because the fruit pulp participates in drying, have richer aroma, enhanced sweetness and body, and more complex flavor. This article compares two Panama Butterfly beans, one natural and one washed, one by one from processing flow, advantages and disadvantages, roasting details to actual brewing parameters, helping coffee enthusiasts understand the flavor changes brought by different processing methods and make choices based on personal preference.

Are coffee beans actually the fruit of the coffee tree? Can they be roasted directly after picking? These questions puzzle many people who are just getting into coffee. In fact, coffee beans are the seeds of the coffee fruit, and they need to go through a series of green bean processing methods to reveal different flavors. Washed and natural, as two mainstream processing methods, show significant differences in workflow, drying time, appearance characteristics, and final cupping performance. Through extensive cupping, Front Street Coffee has found that washed coffee has bright acidity and high cleanliness, while natural coffee has more complex berry notes and higher sweetness. This article will systematically explain the principles and flavor characteristics of these two processing methods to help coffee lovers gain a deeper understanding of the decisive influence of processing methods on coffee flavor.
