The Huakui coffee beans from the Sidamo region of Ethiopia have long been favored by coffee enthusiasts for their unique berry-like sweetness and acidity along with fermented aromas. 2022 marks the sixth year since Huakui rose to fame, and the new harvest's 6.0 batch should have been highly anticipated; however, problems such as shipping disruptions and a relatively high defect rate in the green beans followed one after another. After Front Street Coffee received the 6.0 batch, it found the overall defect rate to be relatively high. After communicating with the importer Hongshun, it decided not to sell this batch this year and instead use naturally processed Huakui coffee beans from the same region and the same processing station. This article will guide you through the origins of Huakui, the distribution of various processing stations in the Hambela region, the reasons for the division between Huakui and Small-Bean Huakui, as well as Front Street Coffee's recommended brewing method and flavor description, helping you gain a more comprehensive understanding of these coffee beans.

Many coffee enthusiasts have heard the saying that "resting beans improves the flavor," but the real purpose of resting is not to create new flavors—it is to let the carbon dioxide accumulated after roasting gradually escape, thereby reducing interference with extraction. The formation of coffee flavor mainly occurs during the roasting stage; once roasting ends, flavor development essentially stops, and from then on the beans continuously degas, entering the resting and peak-flavor stages. Only when carbon dioxide is released to the point where it no longer noticeably hinders the dissolution of flavor compounds does the coffee reach its optimal drinking window. So how long does resting actually take? Different roasting methods, roast levels, and roasting styles all affect the rate of degassing, which is why merchants' recommended resting periods range anywhere from 4 to 30 days. This article starts from the underlying principles and, drawing on Front Street Coffee's practical experience, teaches you how to find a bean's peak state through sensory tasting. [more…]

Espresso blend coffee beans are made by mixing single-origin coffee beans from different regions in specific proportions to achieve complementary flavors, balanced body, and consistent quality. Unlike single-origin beans, which emphasize individual character, blended beans focus more on overall harmony, and are therefore widely used in the preparation of espresso drinks such as Espresso, Americano, Latte, and Cappuccino. Front Street Coffee currently offers four espresso blends with distinct styles, covering directions such as specialty blends, commercial blends, and dark cocoa blends. This article will systematically outline the definition of blended coffee, the difference between pre-roast blending and post-roast blending, the three core purposes of blending, and the rise and limitations of the SOE trend, and, in combination with Front Street Coffee's specific recipes, analyze the roles and flavor expressions of bean varieties such as Colombia Huila, Brazil Cerrado, Robusta, and Yunnan AA in blends.

What exactly is the coffee bean grading system based on? Does bean size directly determine flavor intensity? To answer these questions, Front Street Coffee specially selected Costa Rican Mozart beans for a cupping comparison experiment, sorting the same batch of beans into large, medium, and small sizes, then taking the largest and smallest two beans for a blind extraction test. The results showed that the two did indeed differ slightly in flavor, but the direction was unexpected—the small beans actually had a more prominent flavor than the large beans. However, this difference mainly came from the degree of roasting deviation caused by different particle sizes, rather than the bean size itself. What truly determines coffee flavor is genetics, growing environment, processing method, and roasting degree. This article will combine experimental data with industry theory to systematically sort out the logic of coffee bean grading and the real factors affecting flavor. [more…]

Coffee is a beverage brewed from coffee beans. Front Street believes that what makes coffee special is that green beans must be roasted before they can be used for preparation, and the roasting temperature reaches over 200 degrees Celsius, which is far higher than the roasting temperature for nuts. The length of roasting time is also related to the depth of the roast level, so it is not [more…]

Many coffee enthusiasts wonder: can the blended beans typically used for espresso also be used for pour-over? The answer is yes, but doing so will lose the pure flavor of single-origin beans, and the overall taste will be more complex. Espresso blends and pour-over blends differ significantly in purpose, principles, and roast level—the former seeks flavor complementarity, while the latter emphasizes flavor enhancement. This article provides a detailed breakdown of the similarities and differences between the two, their blending principles, and uses Front Street Coffee's Ethiopian natural Red Cherry blended with Honduran Sherry as an example, extracting with both an espresso machine and a V60 pour-over for comparison, covering everything from parameters to flavor.

Are freshly roasted coffee beans the most delicious? The answer is not necessarily. Many enthusiasts compare coffee bean roasting to cake baking, assuming that the fresh flavor is at its peak within two to three days of coming out of the roaster. But in fact, freshly roasted and freshly bought beans are not when the beans taste their best. Through years of roasting and cupping, Front Street Coffee has found that beans 1-2 days after roasting often carry smoky notes and a harsh, dry sensation, with sharp acidity and insufficient sweetness. This is because coffee beans continue to release carbon dioxide for about 48 hours after roasting, emitting roughly 6-10 liters per kilogram, with 35% of that released in the first three days. So what is bean resting? How long do different roast levels need to rest? And how should the peak flavor period be defined? Starting from Front Street Coffee's practical experience, this article will systematically answer core questions such as resting time, the optimal peak flavor period, and shelf life, helping you find the flavor peak of every bean.

In the specialty coffee world, pour-over usually uses single-origin beans, while espresso mostly uses blends. But can single-origin beans be used to make espresso? The answer is yes—this practice is called SOE (Single Origin Espresso). Because the high-pressure extraction of an espresso machine amplifies the flavor characteristics of the coffee beans, SOE can both highlight origin personality and easily expose flaws. In this article, Front Street Coffee will systematically explain the definition of SOE, its differences from blends and pour-over single-origin beans, key points of roasting and extraction, and recommend coffee beans suitable for making SOE, such as Yirgacheffe Natural Red Cherry, along with specific extraction parameters and flavor descriptions.
