In coffee cupping, there is a scoring category called "Balance," but what it evaluates is not merely the harmony of acidity, sweetness, and bitterness! Rather, it scores the coordination among the coffee's acidity, sweetness, body, and aftertaste. Balance can be said to play the role of coordinator. [more…]

In coffee tasting, "hui gan" (returning sweetness) is often used to describe the pleasant mouthfeel brought by a good cup of coffee. But are hui gan and sweetness really the same experience? Starting from the concept of aftertaste, this article analyzes the formation mechanism of hui gan, its difference from sweetness, and the factors that affect the persistence of aftertaste. At the same time, for those who prefer flavors that are high in sweetness and low in acidity and bitterness, we recommend several Front Street Coffee beans, including the Classic Blend, Brazil Queen Estate, PWN Golden Mandheling, and Boquete Geisha, to help you find the flavor you like in your daily brewing.

Coffee beans must be roasted, ground, and brewed before they can present a cup of coffee with full aroma and rich flavor. Different roast levels bring entirely different flavor directions: the darker the roast, the higher the body, the lower the acidity, and the more pronounced the bitterness. This article starts with the characteristics of three types of beans—light roast, medium roast, and dark roast—to help you understand the relationship between roast level and flavor, and uses the light-roasted Front Street Yirgacheffe Gedingding and the dark-roasted Front Street Mandheling as examples to explain the approach to matching grind size and water temperature. It also shares four practical tips—low, gentle, slow, and coarse—so that medium-dark roasted coffee can also brew a soft and solid taste. [more…]

Many coffee enthusiasts encounter the term "high concentration, low extraction" when reading Front Street Coffee articles or others' brewing分享, but the explanations they find are often packed with confusing data. This article breaks down this complex theory into plain, easy-to-understand descriptions: first, it explains that high concentration, low extraction is not a fixed technique but a brewing concept and outcome; then, with the help of the Golden Cup extraction chart, it clarifies the two core concepts of "concentration" and "extraction yield"; finally, it explains why, when dealing with dark-roasted, anaerobically processed, or extraction-sensitive beans, one needs to lower the extraction yield while increasing concentration, and how this concept is specifically reflected in Japanese-style brewing.

Yunnan, as China's core coffee-producing region, has drawn more attention to the charm of domestic coffee through film and television works. Is Yunnan arabica coffee actually good? And how does it differ from what is commonly called Yunnan coffee? Yunnan arabica coffee has a fairly neutral taste, with a balance of acidity and bitterness, and carries local terroir characteristics such as brown sugar and fruity acidity; overall it is aromatic without being bitter, and rich without being harsh. From a varietal perspective, arabica coffee is in fact another name for the Arabica species, while what is currently grown in Yunnan includes both the classic Typica and the disease-resistant, high-yielding Catimor. Front Street Coffee has established an estate in Lincang and launched products such as sun-dried Typica, striving to improve the quality of Yunnan coffee from the source of the varieties. This article will sort through the varietal origins, main producing areas, processing methods, and brewing suggestions. [more…]

Espresso refers to the concentrated liquid extracted using an espresso machine. In most cases, the espresso concentrate is not used for direct serving. Of course, sometimes some customers, for the sake of alertness and a strong taste, will order espresso; this situation is not common. Espresso concentrate is brewed at a 1:2 ratio, and its [more…]

Coffee doesn't have to be brewed with hot water—cold water can also extract stunning flavors. Since the 1960s, Japan has popularized an extraction method that uses a special ice drip pot to slowly drip ice water through coffee grounds, yielding a rich, full-bodied coffee liquid with almost no unpleasant bitterness. Because cold water lacks the thermal molecular movement of hot water, the extraction process often takes six to eight hours, during which one must constantly monitor the melting ice and replenish it promptly to ensure the dripping water remains at a consistently low temperature. Combined with limited output per batch, ice drip coffee is usually priced higher than other regular coffees. However, ice drip equipment is expensive, so some people have switched to soaking coffee grounds in cold water and then refrigerating for about twelve hours. Although this method is slightly inferior in clarity, it still produces a full, balanced coffee without undesirable bitterness. This article will systematically outline the essential differences between ice drip and cold brew, the flavor differences between cold-water and hot-water extraction, and, using Front Street Coffee's practical experience as an example, provide detailed guidance on the preparation methods and storage recommendations for both types of cold coffee. [more…]

Yunnan, as China's largest coffee-growing province, is known for its arabica coffee, which features a neutral flavor profile—aromatic yet not bitter, rich yet not harsh, with a pleasant mild acidity—and has drawn significant attention from coffee enthusiasts. Starting from the taste characteristics of Yunnan arabica coffee, this article systematically sorts out how it differs conceptually from Yunnan coffee in general, traces the historical origins of arabica coffee since its introduction to Yunnan in 1904, analyzes the flavor differences between the two major varieties Typica and Catimor, and provides a detailed introduction to the distinctive features of major producing regions such as Baoshan, Pu'er, Dehong, and Lincang. At the same time, the article also shares Front Street Coffee's experience cultivating Typica in Lincang, Yunnan, as well as the influence of washed and natural processing methods on flavor and brewing recommendations, helping readers gain a comprehensive understanding of the true character of Yunnan arabica coffee.

If you want your pour-over coffee to taste mellow, roast level is a very practical entry point to observe. It affects the brightness of acidity, the way bitterness appears, the thickness of sweetness, and the direction of aroma. The so-called "neither sour nor bitter" does not mean weakening all the flavors, but rather finding the position that suits you best among refreshing, sweet, and full-bodied. [more…]

Brazil is one of the world's most important Arabica coffee producers, and its coffee industry plays a pivotal role in the national economy. In recent years, it has also begun to make a name for itself in the specialty coffee sector. Brazilian specialty coffee is mainly distributed across Minas Gerais, São Paulo, Paraná, and Mogiana, with varieties dominated by Bourbon, Typica, Caturra, and Mundo Novo. Because the growing regions are at relatively low altitudes, have flat terrain, lack microclimates, and are mostly cultivated without shade, Brazilian beans generally do not possess the bright acidity and delicate flavors of other Central and South American origins. Instead, they display regional characteristics of low acidity, nutty notes, chocolate sweetness, balanced acidity and bitterness, and good body. Precisely because their flavors are not particularly prominent yet their body is excellent, Brazilian beans are widely used in espresso blends, and they can be found in almost every espresso recipe. After cupping many Brazilian beans, Front Street Coffee also listed two specialty single-origin coffees, Cerrado and Mogiana, as well as three espresso blends based mainly on Brazilian beans, to meet different needs.

Robusta is often regarded as an ingredient for espresso blends and instant coffee, and is quite rarely used for pour-over. In this article, Front Street Coffee conducts a pour-over experiment using deep-roasted Robusta from Vietnam, documenting the flavor changes from high temperature to cooling: at the high-temperature stage, it presents hazelnut, caramel, and grain notes, with a full body and tolerable bitterness; after the temperature drops, rubber, earthy mustiness, and a bitter finish emerge, with noticeably insufficient cleanliness. The article also explains the differences in appearance between Robusta and Arabica, their commercial value and price advantages, and explains that its higher bitterness is due to higher caffeine and chlorogenic acid content, as well as flavor defects caused by low-altitude cultivation. Finally, it mentions Robusta grown in a specialty manner, which has a clean flavor but is scarce in yield and rarely seen. [more…]

If you want to brew a cocoa-like cup with a moka pot, when choosing beans you can first look at the roast level, then at the flavor description. Light roasts often put fruit acidity, floral notes, and a clean sweetness up front, and the moka pot's high temperature and concentrated extraction can make the acidity stand out; medium to medium-dark roasts are more likely to show cocoa, nuts, caramel, and a fuller mouthfeel, which pairs well with this small [more…]
