How long does it actually take for green coffee beans to go from hitting the pan to being roasted? In order to hear the sound of "first crack" with his own ears, Front Street Coffee deliberately conducted three rounds of home-roasting experiments using a frying pan and an open flame on a stove, testing the performance of naturally processed Santa Vini and washed Kafa Forest under different heat levels. The article records the time points for each batch of beans' color change, silver skin shedding, and the appearance of cracking sounds, as well as the final cupping flavor differences, while also sharing practical experience on how to judge heat level and the timing for taking the beans out when there is no professional coffee roaster.

In the process of learning coffee roasting, there is often a gap between theoretical understanding and hands-on practice. This article focuses on judging two key milestones—the yellowing point and first crack—analyzing one by one the visual and auditory misjudgments that beginners easily make. It also offers temperature and aroma as auxiliary indicators for the yellowing point, and explains how misjudging first crack can lead to grassy, underdeveloped flavors and astringency in coffee. Drawing on Front Street's roasting course philosophy, the article also reminds readers not to mechanically copy curve data, but to understand the logic behind the data, so as to find a roasting path that truly suits them.

Want to learn how to roast coffee? Start by getting to know the tools and the terminology. Roasting coffee beans looks as simple as stir-frying vegetables, but doing it well requires a solid foundation of knowledge. In this article, Front Street Coffee will walk you through several common coffee roasting devices—direct-fire, semi-direct-fire, and hot-air roasters—covering their respective heat transfer principles, advantages, and drawbacks. At the same time, we'll systematically sort out the professional terms that come up during roasting, including charge point, turning point, yellowing point, first crack and second crack, as well as stage concepts like the drying phase, browning phase (Maillard), and development phase. Mastering this foundational knowledge is an important prerequisite for actually roasting beans, judging the roasting pace, and controlling the direction of flavor—and it can help you avoid detours and roast a good batch of beans faster.

The processing method of coffee cherries directly affects the flavor expression of green beans, and among these, the natural process and the washed process are the two most representative techniques. The natural process originated in the Arabian region over a thousand years ago, relying on natural drying to allow the fruit to slowly mature internally; the washed process was invented by the Dutch in the 18th century, using fermentation to remove the mucilage layer and thereby improve the bean's cleanliness. The two differ noticeably in operational steps, suitable environments, and final cupping performance, and understanding these differences helps in more accurately selecting and tasting coffee. This article will separately outline the complete processing flows of the natural process and the washed process, and explain the flavor characteristics each brings. [more…]

Is the sourness in coffee good or bad? Some people believe that sourness means the coffee is not fresh, while others regard it as a hallmark of high-quality coffee. In fact, green coffee beans themselves are rich in organic acids, most of which decompose or disappear after roasting, leaving only a limited variety of organic acids in the final cup. The latest research shows that there are not many acids that our taste buds can clearly identify, and much of the fruity acidity we perceive actually comes from the combined association of sourness with other flavors. The latest SCA cupping form classifies acidity into two categories—"sweet type" and "dry type"—helping us more accurately judge whether a coffee's acidity is good or bad. This article, from the professional perspective of Front Street Coffee, will provide an in-depth analysis of the sources of coffee acidity and the criteria for evaluating it. [more…]

The structure of a coffee cherry, from the outside in, consists of the skin, pulp, mucilage layer, parchment layer, silver skin, and the coffee bean. The essence of a processing method is to remove these outer layers, retain the bean, and dry it. Honey processing falls between washed and natural processing, and is especially common in Costa Rica. Based on the proportion of mucilage retained, it is classified into different grades such as yellow honey, red honey, and black honey, with the more difficult raisin honey process also existing. This article breaks down in detail the complete honey processing workflow, the grade classifications, and the differences in drying, and includes recommendations for representative Costa Rican beans from the Front Street brand, helping coffee enthusiasts fully understand the flavor code of honey processing.

Coffee beans transform from green raw beans into brown roasted beans entirely through the key process of roasting. The length of roasting time directly determines the depth of the bean surface color and also shapes completely different flavor directions. The roasting color standard card established by the Specialty Coffee Association of America (SCAA) divides roast levels into eight grades, from light roast to Italian roast, with each level corresponding to a specific drop time and flavor characteristics. In addition, emerging concepts such as Nordic ultra-light roast and Japanese ultra-dark roast have gradually entered the view of enthusiasts. This article will systematically sort out these eight levels, the five stages of roasting, and the classification methods used by Front Street Coffee in practical applications, helping readers build a complete understanding of coffee roast levels.
