Coffee enthusiasts often notice that the coffee beans they buy vary in color from light to dark, and suspect a roasting problem.

This article starts from the common questions received by Front Street Coffee's customer service to explain how factors such as the uneven size of Ethiopian beans, residual pectin sugars in honey processing, and anaerobic processing cause color variation in coffee beans—and why this variation is sometimes a plus for flavor.

Coffee beans are not naturally the dark brown beans we know; rather, they are encased in fruit that resembles red dates. From harvesting, processing, and roasting to brewing, every step subtly influences the final flavor, and among these, the "processing method" is the primary key that determines the direction of coffee flavor. Washed and natural are currently the two most common methods of green bean processing; the former relies on sun exposure, while the latter requires ample water and fermentation tanks. This article takes Front Street Yirgacheffe as an example to compare in detail the specific differences between washed and natural coffee beans in dry aroma, mouthfeel, and pour-over parameters, helping coffee enthusiasts understand the characteristics and suitable scenarios of the washed processing method.

Have you ever met a coffee expert like this—one who can pick up a single bean, take one look, and tell you its variety and origin? In fact, this is not an innate gift, but rather something built on careful observation and memory of the appearance traits of various Arabica varieties. Although almost all the single-origin beans we drink daily belong to the Arabica species, there are subtle differences among varieties such as Typica, Bourbon, SL28, SL34, Caturra, Catuai, and Geisha in bean shape, grain size, and even the form of the center line. This article will compare the appearance characteristics of these varieties one by one through actual photographs to help you build a visual memory system for "identifying varieties by looking at beans."

Among various types of black coffee, cold brew is often priced the highest, creating a stark contrast with the affordable Americano. This price difference is no accident—it stems from fundamental differences in extraction methods and the coffee beans used. Americano is based on espresso, simply diluted with water, making it flexible and quick to prepare; cold brew, on the other hand, encompasses various forms such as ice drip and cold steep, requiring long, slow extraction with ice water, which comes at a higher time cost. More crucially, Americano typically relies on dark-roasted commercial blend beans to accommodate milk coffee offerings, while cold brew often uses specialty beans with traceable flavors, which demand higher cultivation and processing standards, with costs accumulating layer by layer. This article will analyze the sources of the price difference between cold brew and Americano from three dimensions—water temperature, time, and beans—and share Front Street Coffee's bean selection recommendations for cold brew.
