The peak flavor period refers to the optimal window for tasting coffee beans after roasting is completed. During this time, because there is not too much carbon dioxide interference, and the coffee's flavor compounds have not yet been lost in large amounts, we can brew coffee with the richest aroma and obtain the most complete flavor experience. But did you know, [more…]

Wetting the filter paper before brewing coffee is almost a standard step for all pour-over enthusiasts, with the usual goals of making the filter paper fit snugly, removing paper dust, and, if hot water is used, warming the cup along the way. However, most tutorials rarely discuss in depth how much the degree of fit between the filter paper and the dripper actually affects the final taste. Front Street conducted two sets of controlled experiments, using V60 and KONO drippers respectively, paired with filter papers in different states of fit for brewing, and tasted and compared them one by one. The experiment used the floral-fruity Front Street · Gedin Gedin and the nutty-sweet Front Street · Brazil Red Bourbon, and the results showed that a poorly fitting filter paper significantly changes the flow rate, which in turn affects the extraction yield and concentration, producing noticeable differences in mouthfeel.

The flavor expression of coffee depends not only on the quality of the green beans, but is also closely related to the degree of roasting and the extraction method. In this experiment, coffee beans at three different roast levels—light, medium, and dark—were selected and extracted using two methods, cold drip and pour-over, to compare their specific differences in aroma, acidity, mouthfeel, and aftertaste. Light roast in cold drip presents fresh notes of citrus, jasmine, and honey, while pour-over shows bright acidity and a clean mouthfeel; medium roast in cold drip brings the sweetness of rose, grape, and blueberry, while pour-over presents the richness of chocolate and caramel; dark roast in cold drip has a pronounced oily body and a smooth mouthfeel, while pour-over is intense with a slight burnt bitterness. The article also recommends representative Front Street Coffee beans for each roast level, providing a reference for coffee lovers when purchasing and brewing. [more…]

Because American soldiers during World War II were not used to the extremely strong small cups of coffee local to Europe, they asked the shops to add hot water to dilute it, imitating the taste and flavor of American drip coffee. And because this cup of coffee was widely popular among American soldiers, it was named Americano "America [more…]

Compared to the straightforward expression of espresso, pour-over coffee presents its flavors more subtly, and tasting it requires more patience and method. From the perspective of Front Street, this article systematically sorts out the tasting path for pour-over coffee: from the dry aroma after grinding to the wet aroma during brewing, from the sweet, sour, bitter, and salty tastes brought by water-soluble substances to the flavor identification involving retronasal olfaction, and then to the mouthfeel experience determined by insoluble substances. The article also analyzes the causes of richness and thinness, the sources of astringency, and the influence of roast level on mouthfeel, helping coffee enthusiasts establish a correct tasting framework before identifying specific flavors and find a more efficient way to perceive them.

A freshly ground and brewed cup of coffee, like the coffee beans themselves, has its own optimal tasting window. Coffee aromas volatilize easily, and temperature constantly affects how the taste buds perceive sweetness, acidity, and bitterness. Therefore, from the moment it is brewed, the flavor continuously changes with time and temperature. Front Street Coffee compares the tasting performance of dark-roasted Golden Mandheling and light-roasted Gedinding at different time points, documenting the evolution of aroma, mouthfeel, and taste, to find the limit of coffee's tasting window under normal standing conditions. It will also answer common questions such as whether reheating can restore the flavor, and how to extend aroma retention with a lid or thermos, helping you seize the most brilliant drinking window of every cup of coffee.

Ice drip coffee and cold brew coffee are two common methods of making cold coffee, and the two differ noticeably in production process, extraction time, and final flavor. Front Street Coffee conducted a synchronized experiment using the same sun-dried Huakui coffee beans, comparing the production methods and resulting performance of ice drip and cold brew in an all-round way, from grind size calibration to powder-to-liquid ratio setting, and then to extraction time and post-processing methods. The experimental results showed that ice drip coffee was clear and bright, with a clean and refreshing mouthfeel, carrying fermented notes and a faint berry-like sweet acidity; cold brew coffee, by contrast, had a full-bodied mouthfeel and uniform flavor, with prominent fruity sweetness and a weaker fermented note. This article will analyze in detail the differences in production methods between the two types of cold coffee, the experimental plan, and the flavor comparison results, to help coffee enthusiasts more clearly understand the characteristics of both and the basis for choosing between them.

Segmented pouring in pour-over coffee seems simple, but in reality, even subtle changes in the water volume of each segment leave their mark in the cup. Many friends new to pour-over are often puzzled: how exactly should the water volume after blooming be divided? And in what direction do different distribution schemes take the flavor? Front Street used the Yirgacheffe Gote Gote as a sample and designed three comparative experiments, fixing the dose at 15 grams, the coffee-to-water ratio at 1:16, medium-fine grind, and water temperature at 91°C, changing only the water volume ratio between the second and third pours, to observe how acidity, sweetness, mouthfeel, and finish trend. The experiment also revealed the potential impact of the relationship between the height of the coffee bed wall and the water level on extraction uniformity, and offers reference ideas for flexible adjustment in actual practice.

But when the weather is too hot, we always find it hard to [more…]

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…]

The difference between a hot americano and an iced americano ultimately comes down to whether the espresso is combined with hot water or iced water. This seemingly simple combination actually involves a lot of nuance—water temperature, the coffee-to-water ratio, and the timing of tasting all influence the final flavor of an americano. This time, Front Street Coffee brewed hot americanos with four different water temperatures—55°C, 65°C, 75°C, and 90°C—and compared them at three points in time: just after brewing, 5 minutes later, and 20 minutes later. Using measured data, we’ll tell you which temperature is best for serving a hot americano for dine-in, and reveal the complete pattern of how coffee flavor changes over time at different water temperatures.

In a cup of black coffee, water makes up the vast majority, so its impact on flavor must not be underestimated. Different brands of drinking water vary in mineral composition, hardness, and pH, so the coffee brewed with them naturally takes on different characteristics. To investigate this variable, Front Street Coffee selected four common drinking waters—Baisui Mountain, Nongfu Spring, Ganten, and C'estbon—and used the same Costa Rica Mozart coffee beans to make cold brew, measuring TDS, coffee liquid concentration, and recording flavor performance one by one. The experiment found that the amount of calcium and magnesium ions in water affects extraction efficiency and taste direction, while Nongfu Spring with medium TDS and C'estbon purified water each showed distinct stylistic differences. This article will present the full experimental process and tasting results, and offer water selection suggestions for different taste preferences. [more…]
