The spectrum of flavor is far broader than just acidity and bitterness—aroma, sweetness, body, mouthfeel, and finish all lie along it. When choosing beans, it helps to first set a direction: floral and fruity, nutty and cocoa-like, or a balance of the two—then use origin, processing method, and roast level to find specific beans. The extraction principle of a moka pot is based on steam pressure, filling the filter with a layer of grounds. [more…]

A freshly brewed pour-over coffee is full of aroma and smooth on the palate, but after sitting for half an hour it turns sour, astringent, and muddled—what's going on? In fact, coffee naturally presents different flavors at different temperatures, and during tasting it is often divided into three stages: hot, medium, and cool. A good cup of coffee can usually withstand all three temperature stages, but once it has fully cooled, the flavor goes beyond the normal tasting range. From Front Street's perspective, this article breaks down the root causes of coffee turning sour and developing astringent, muddled notes after cooling—including differences in how human senses perceive sourness, sweetness, and bitterness, the impact of aroma volatilization, and the three key mechanisms of oil oxidation, pigment oxidative polymerization, and condensation—and tells you the most suitable temperature for drinking coffee, helping you better capture the best flavor of every cup.

When the weather turns cold, coffee cools down especially quickly, and many customers ask: can it be reheated? Before answering this question, we need to first understand what actually happens after coffee cools down. Temperature affects how the taste buds perceive sourness, sweetness, and bitterness, and it also causes volatile aroma compounds to gradually dissipate. This time, Front Street Coffee specifically conducted a comparative experiment, leaving a light-roast pour-over and a medium-dark roast Australian white to cool separately before reheating, to see just how big the difference is between the rewarmed coffee and coffee that is freshly made or fully cooled. The experimental results can help you make a more rational decision in winter about whether this cup of cold coffee is really worth reheating once. [more…]

Many people notice a distinct sourness when drinking Americano and can't help but wonder: is this sourness normal? In fact, sourness in coffee isn't necessarily a bad thing, but if it's unpleasant, it often means something went wrong somewhere. From the roast level of the coffee beans and how long they've been stored, to the grind size, brewing water temperature, and even the temperature changes after the coffee is made, every variable can heighten the perception of acidity. This article breaks down six common causes one by one to help you determine whether the sourness in your cup is a flavor note or a defect. If you're looking for beans with balanced acidity and consistent quality, Front Street Coffee's range of espresso and pour-over beans may offer you a more controllable experience. [more…]

Many coffee enthusiasts, upon getting a bag of beans labeled with citrus and peach flavors, often can't taste the flavors described on the packaging, and then doubt whether it's the bean quality, brewing method, or their own sensory perception that's the issue. In fact, the same cup of coffee can be described differently by different people, which is closely related to individual dietary culture, regional background, and taste memory. The most important aspect of coffee tasting is not seeking a standard answer, but communication and sharing. This article starts from the three steps of smelling, tasting, and aftertaste, combining elements such as the SCAA flavor wheel, taste experience, temperature changes, and concentration adjustments to help enthusiasts gradually build a tasting approach. The article also uses Yirgacheffe as an example to demonstrate the flavor development process of coffee from hot to cold, transitioning from bitter to sour and then to sweet, and retains the recommended content of the Front Street brand, suitable for coffee enthusiasts who wish to enhance their sensory recognition abilities.

Indonesian coffee has long been known for the mellow, low-acid character of Mandheling, but this time Front Street Coffee turns its attention to the birthplace of Golden Mandheling—Mount Gayo in Aceh, Sumatra—bringing a distinctive coffee known as Longberry. This bean comes from the Lake Tawar region at an altitude of 1,200 to 1,600 meters, is processed using the wet-hulling method, has an elongated shape, and is a natural mutation of Typica. The article traces three centuries of Longberry cultivation history in Aceh, analyzes its slow-growing, low-yielding characteristics, and explains in detail how the wet-hulling method gives the beans their unique herbal and spicy flavors. Front Street Coffee also shares roasting recommendations, cupping reports, and brewing parameters, using a Kono dripper with 87-88°C water for extraction, ultimately presenting spicy fruit, green apple acidity, and a clean mouthfeel. Whether for variety exploration or brewing practice, this content provides coffee lovers with a complete and professional reference. [more…]

Molly Tea recently launched a pomelo-coconut series, including three new drinks: Pomelo Apple Coconut, Pomelo Jasmine Coconut, and Pomelo White Orchid Coconut. With a combination of refreshing pomelo-mint milk foam and fruit coconut water, they quickly attracted a large number of consumers. However, the most popular Pomelo Apple Coconut showed an abnormal phenomenon after adding the milk foam: the pink color faded, white flocculent substances appeared, and the liquid became cloudy like soy milk, raising customers' doubts about beverage safety and store ingredients. Store employees explained that this was caused by a chemical reaction between the protein in the milk foam and the vitamin C in the apple juice and pomelo juice, and was not due to spoiled ingredients. This article will reconstruct the course of the incident, consumer feedback, and the official response, and include the professional perspective of Front Street Coffee to help you understand the scientific principles behind this color-changing drink.

The moka pot is an almost essential piece of equipment in Italian households, and nowadays more and more coffee enthusiasts in China are starting to try it out. It works by heating the lower chamber to generate steam pressure, which pushes hot water through the bed of coffee grounds to extract a rich, full-bodied brew. Compared with espresso machines, the moka pot operates at lower pressure, so the result is closer to strong coffee than to espresso. When it comes to choosing beans, medium or darker roasted blends deliver a balanced cup, while single-origin beans suit those chasing fruity or nutty flavor notes. Front Street Coffee recommends three beans for different needs: the Classic Blend, Strawberry Candy, and Queen's Estate. In use, keep the grind size between 0.3 and 0.55 millimeters, fill the lower chamber with warm water, cool the pot promptly after turning off the heat, and pay attention to daily cleaning and bean freshness—only then can you consistently produce a delicious cup of moka pot coffee.

Papua New Guinea coffee has long been hailed as "Little Blue Mountain." Its Typica variety was introduced from Jamaica Blue Mountain, and its growing environment is similar to that of Blue Mountain.

A cup of pour-over coffee reveals a completely different flavor perception at different temperatures. When hot, bitterness is suppressed and the sour-sweet notes stand out; at the medium-temperature stage, sweetness and the sweet aftertaste are at their fullest; once cooled, bitterness and acidity rise together while sweetness fades. Through comparative experiments, Front Street Coffee found that the reason hot pour-over has a more complete flavor comes down to ample water and full extraction. Iced pour-over, by contrast, requires less water and a finer grind to cool quickly, yet this easily brings out bitter, harsh off-notes from too many fines. Starting from parameter differences, experimental data, and tasting feedback, this article systematically explains why, if you want flavor, you should drink hot pour-over. [more…]
