After coffee beans come out of the roaster, they continue to release carbon dioxide internally, and this degassing process directly determines whether the aromatic compounds can be extracted smoothly during brewing. Because blended beans and SOE differ in bean composition and roasting direction, their pace of reaching the optimal drinking state and the period for maintaining aroma each have their own characteristics. Single origin [more…]

Freshly roasted coffee beans enter a degassing phase in the early stage, during which the carbon dioxide trapped inside is slowly released over time. If brewed immediately at this point, the water flow tends to be blocked by the bubbles, preventing the flavor compounds from dissolving out evenly. Letting the beans rest in a bag with a degassing valve for a period of time allows the internal pressure to stabilize. This process [more…]

Freshly roasted coffee beans accumulate a large amount of carbon dioxide gas within their bodies, making them unsuitable for immediate grinding and brewing in the first few days after roasting. When hot water is poured in, the gas is released violently, forming a dense barrier layer that hinders full contact between the water flow and the coffee grounds. Through a resting and degassing period ranging from several days to more than ten days, the internal aroma molecules [more…]

Freshly roasted espresso beans contain a large amount of carbon dioxide gas trapped inside. This gas is slowly released over time, and in the early stage it produces a relatively vigorous degassing reaction. If the beans are ground and extracted immediately after roasting, the bubbles tend to hinder full contact between the water flow and the coffee particles, resulting in an unstable extraction flow. [more…]

Drip bag coffee, with its convenience and high cost-effectiveness, is attracting more and more beginners to the fold. But many friends who are new to coffee often wonder: how many times can one drip bag actually be brewed? Why can tea leaves be steeped repeatedly, while coffee is usually extracted only once? This article starts with the composition of soluble substances in coffee beans, focuses on analyzing the role of chlorogenic acid in the extraction process, explains why coffee is not suitable for multiple brews, and also touches on why a second pour is not recommended after a regular brew. It also compiles Front Street Coffee's drip bag recommendations for different tastes, for everyone's reference when choosing. [more…]

The dense, golden layer of crema on the surface of an espresso is essentially a foam formed when carbon dioxide inside the coffee beans, carrying aromatic oils, is emulsified under high-pressure water. Freshly roasted coffee beans trap a large amount of gas inside, and this gas is slowly released over time, determining the thickness and condition of the crema during extraction. Understanding [more…]

Roasted coffee beans contain abundant carbon dioxide internally, and these gases can participate in forming a golden, delicate crema during extraction. However, during the stage of extremely vigorous degassing, excessive bubbles tend to hinder uniform contact between water flow and coffee particles, making the flavor in the cup appear unsettled. Understanding how coffee beans evolve in condition across different time periods, [more…]

After light-roasted coffee beans leave the roaster, subtle gas exchange continues inside them. The large amount of carbon dioxide accumulated during roasting slowly escapes through the loose fibrous structure, and this natural release process directly affects the penetration efficiency of hot water molecules. Understanding the breathing rhythm of coffee beans can help me [more…]

Espresso extraction is extremely sensitive to the state of the carbon dioxide inside the coffee beans, and the completion of roasting does not mean the beans immediately reach the balance point for aroma release. Freshly roasted coffee beans are packed with a large amount of gas inside. If pressurized extraction is carried out right away, the water flow is easily obstructed by bubbles, leading to uneven extraction and bringing out too many off-flavors. Understanding [more…]

From the moment coffee beans finish roasting and leave the roaster, the aromatic compounds and carbon dioxide inside them begin a dynamic process of change. Machine extraction relies on a steady flow of water and pressure, and is especially sensitive to how filled with gas the inside of the beans is. Freshly roasted beans retain a large amount of carbon dioxide inside, so if they are placed directly into the machine for extraction [more…]

The same coffee beans, extracted with a different approach, will yield a completely different flavor in the cup.

The initial period after roasting is [more…]

Have you ever been like Front Street Coffee, filled with curiosity about the story behind the cup of coffee you drink every day? From the seed first planted to the final rich aroma in the cup, a coffee bean must go through multiple stages: cultivation, picking, post-processing, transportation, roasting, grinding, and extraction. The Arabica coffee tree has strict requirements for its growing environment—temperature, rainfall, altitude, and soil are all indispensable. After picking, the coffee cherries must also undergo processing such as sun-drying before they become green beans, and then through roasting they develop their captivating flavors. This article will take you through the complete journey of a coffee bean from the field to the cup, helping you understand how each step affects the final flavor. [more…]

Although Bolivia is a low-output, niche coffee-producing country, it produces specialty coffee beans with distinctive flavors. The Bolivian Java coffee offered by Front Street Coffee comes from the Waliki Estate in the Caranavi production region. The estate covers only six hectares and sits at an altitude of over 1,660 meters. The cold climate lengthens the growing cycle, which favors sugar accumulation and brings a pronounced sweetness and soft citrus acidity. This article will introduce the varietal characteristics, processing methods, transportation difficulties, and cupping and pour-over performance of Bolivian coffee, and compare it with Indonesian West Java coffee beans, helping readers gain a comprehensive understanding of the unique charm of this niche origin.

The Sidamo producing region is located in the southern highlands of Ethiopia, bordering Kenya, and is a famous specialty coffee origin. The terrain here is diverse, the volcanic soil is fertile, and soil fertility is maintained through the cycling of organic matter, creating a rich diversity of coffee flavors. Front Street Coffee's Sidamo green beans are grayish-green, with uneven bean sizes, an acidity that is both soft and intense, a medium body, and notes of sweet spice. The washed process displays citrus notes, nutty creaminess, and a slight cocoa aroma, with a smooth and syrupy mouthfeel; the bright lemon-like fruit acidity and gentle entry create a strong impact, with a distinctive sweet aftertaste. The natural process, by contrast, is closer to floral notes, rich in fruity sweet-and-sour flavors, and delicate in texture. A light-to-medium roast is suitable for single-origin brewing, while a medium-dark roast can be used for blended coffee or as an Espresso base. This article will introduce in detail the flavor of washed Sidamo, the origin of the Hualei estate, the processing methods, and brewing suggestions. [more…]

The flavor of coffee depends not only on the altitude, soil, and climate of its origin—the harvesting method also has a key impact on quality. Although machine picking is highly efficient, it struggles to distinguish the ripeness of the fruit; manual harvesting, by contrast, allows selection by ripeness, and is especially more reasonable in high-altitude mountainous areas. In 2007, the Dutch green bean trader Trabocca launched the "Red Cherry Project," requiring 100% fully ripe red cherries to be picked entirely by hand, with strict quality control through two rounds of cupping, and using high prices to incentivize coffee farmers to produce with care, breaking the previous vicious cycle of "valuing weight over quality." This article will walk you through how the Red Cherry Project operates and recommend a Front Street Coffee sun-dried Red Cherry coffee bean—a Yirgacheffe G1 grade bean, processed by the traditional sun-dried method, with full fruit aromas and a black tea finish, suitable for pour-over, cold brew, espresso SOE, and many other extraction methods.
