To brew a delicious cup of loose-leaf tea, the order in which you add the tea leaves and the water matters a great deal. Traditional Chinese brewing methods fall into three categories: the top-drop method, the mid-drop method, and the bottom-drop method, each suited to tea leaves of different tenderness and form, and also closely tied to the season and air temperature. Experienced tea drinkers choose flexibly based on the type of tea, the age and tenderness of the leaves, and the air temperature. This article lays out the steps and precautions for all three methods, including key details such as the tea-to-water ratio, water temperature control, and timing for pouring off the liquor, along with practical photo demonstrations. Whether you have Biluochun, West Lake Longjing, or Huangshan Maofeng on hand, you can find a brewing plan that suits you and easily avoid common problems like over-steeping or leaves that refuse to sink.

The alluring flavor of coffee depends to a great extent on the physical and chemical changes that occur during roasting. From bean drop through dehydration, first crack, and second crack, every temperature node and duration shapes what ultimately ends up in the cup. In this article, Front Street Coffee will systematically walk through the temperature progression of each stage of coffee bean roasting, and, using a natural-process Yirgacheffe as an example, compare the specific flavor differences in cupping among light, medium, and medium-dark roasts, while also introducing the Agtron color value as a scientific criterion to help readers more accurately understand the correspondence between roast level and flavor. In addition, the article compiles representative beans from Front Street's lineup at different roast levels, making it easy for coffee lovers to follow the guide and find the cup that suits their taste.

The color differences that coffee beans display after roasting are not arbitrary; the industry long ago established a scientific quantitative standard—the Agtron color value, also known as the caramelization analysis number. This set of values runs from 95 to 25, corresponding to eight levels from light roast to Italian roast: the higher the number, the lighter the color, and the lower the number, the darker it is. Each color value range has a clear drop time node and flavor characteristics: from light roasts dominated by bright acidity, it gradually transitions to dark roasts dominated by bitterness and smoky notes. Understanding these color values not only helps us recognize the correspondence between roast level and taste, but also helps us understand why very dark roasts are now hard to find under the specialty coffee trend. But color value is only a reference tool; in actual judgment, tasting perception is still needed, since factors such as processing method also affect the appearance of the beans. [more…]

What degree of coffee roasting is considered appropriate? Starting from the key milestone of first crack, this article systematically sorts out the logic for determining coffee bean roast level, and with the help of Agtron color values, divides roast degree into eight levels: light, cinnamon, medium, deep, city, full city, French, and Italian, explaining one by one the timing for dropping each level and its flavor direction. At the same time, it answers the correspondence between the Roasting percentage markings commonly used by roasters and Agtron color values, helping coffee enthusiasts quickly understand the roasting information on packaging. The article also includes Front Street Coffee's specialty bean recommendation channel for further communication and purchasing. [more…]

Cold brew coffee is a popular iced coffee in summer, also known as Dutch drip coffee or water drip coffee. It relies on ice water dripping through the coffee grounds one drop at a time, undergoing low-temperature extraction over several hours to slowly dissolve the aromatic substances in the coffee. This brewing method requires controlling the drip rate, typically 40–50 drops per minute, and extracting 1000ml takes about 5 to 8 hours. The finished cold brew coffee tastes even better after refrigerated storage, with days 3 to 7 often regarded as the optimal drinking period. As for which beans to choose, it is recommended to prioritize light to medium roast single-origins with pronounced fruity notes and prominent aromas. In addition to outlining the principles of cold brew preparation and six operational steps, this article will also introduce four Front Street Coffee beans suitable for cold brew, including Front Street Huakui, Front Street Kenya Little Tomato, Front Street Sidra, and Front Street Butterfly, for coffee enthusiasts' reference.

When the weather turns cold, many coffee enthusiasts notice that even with the same beans and the same technique, the coffee they brew comes out weak and lacking in flavor. This is not a problem with the bean roasting, but rather the low-temperature environment changes the rate at which the hot water loses heat, which in turn affects extraction efficiency. Starting from the principle of heat loss, this article explains in detail how cooling leads to under-extraction, and offers four actionable improvements: preheating the kettle spout, raising the water temperature, increasing the water volume, and lowering the pouring height. Finally, it includes Front Street Coffee's store information to help you consistently produce a delicious pour-over even in the cold season. [more…]

Many coffee enthusiasts rely on the rule of thumb that acidity means light roast and bitterness means dark roast to judge the degree of roasting, but the industry has a more precise standard—the Agtron color value. From the perspective of Front Street Coffee, this article systematically sorts out a total of eight levels from light roast to Italian roast, and, combined with the timing of first crack and second crack for dropping the beans, explains the flavor direction and the changes in acidity and bitterness at each stage, and also explains the meaning of terms such as City Roast. At the same time, Front Street also shares how to use flavor descriptions to help consumers judge the roast level more intuitively, and gives brewing parameter suggestions corresponding to medium-light roast and medium-dark roast, so that you no longer feel troubled by technical terms.

Recently, prices for both Arabica and Robusta coffee in the international market have been on the rise. The main driver behind this is that Vietnam, the world's second-largest coffee producer, is experiencing a severe drought, causing Robusta coffee output to decline and global inventories to tighten accordingly. Vietnam's National Center for Hydro-Meteorological Forecasting has issued a level-2 drought warning for five provinces—Quang Tri, Quang Ngai, Binh Thuan, Phu Yen, and Gia Lai—and warned of possible natural disasters. Rainfall in the central and Central Highlands regions has been significantly lower than in previous years during the same period, with water levels in many rivers dropping to historic lows. The Mekong River's water level has even broken its lowest record since 1926. The combination of drought and salinization has caused coffee trees in the flowering stage to wither and develop yellow leaves, and output in some producing areas may drop by as much as 30% to 50%. Local coffee purchase prices have soared to 120 million Vietnamese dong per ton, an annual increase of 250%, putting pressure on traders' cash flows. This article will review the development of the drought, production forecasts, and price trends, and also examine how brands such as Front Street Coffee are responding amid raw material fluctuations.

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.

When cold air arrives, the extraction rhythm of pour-over coffee often gets thrown off. The originally set water temperature of 92°C may drop to only 87°C by the time it reaches the coffee bed, and a sudden drop in ambient temperature causes hot water to lose even more heat in the air, leading to under-extraction and a weak, flat flavor. In addition to raising the water temperature by 1–2°C or lowering the height of the pour, preheating the server and dripper can also significantly slow heat loss—an unheated server will cause the coffee liquid to drop to around 69°C, while after preheating it can be maintained at around 75°C. In addition, the static electricity generated during grinding in cold weather cannot be ignored either; coffee grounds tend to clump or stick to the grinder, which can be effectively solved with a distribution needle and a blower. This article starts with three key details to help you keep every cup of pour-over performing steadily. [more…]

Many coffee enthusiasts, beyond their daily consumption, have begun trying their hand at roasting coffee beans. However, home roasting often runs into the problem of uneven bean color, and the degree and consistency of roasting are exactly what determine the final flavor in the cup.

Common labels on coffee bean packaging such as light roast, medium roast, and cinnamon roast often confuse beginners. The roast level directly determines the direction of coffee flavor, and historically different countries and regions have had their own schools of thought for defining roast levels, lacking a unified standard. The Specialty Coffee Association of America, together with Agtron, used infrared caramelization measurement values as the basis to divide roast levels from light to dark into eight grades, which has become an important industry reference. In this article, Front Street will systematically introduce the Agtron color values, drop times, and flavor characteristics of each roast level, and share how to judge the roast level through flavor descriptions, as well as the grinding degree and water temperature parameters that should be used for different roast levels.
