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 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 single-origin coffee beans hold a large amount of carbon dioxide gas trapped inside. In the first days after opening, this gas rushes out violently on contact with water, forming a dense layer of foam. Too much gas prevents water from fully contacting the coffee grounds, so aromatic compounds cannot dissolve out smoothly. Give the beans a quiet period to degas. [more…]

When buying Yirgacheffe beans, the roast date is often more worth checking first than the flavor words on the packaging. Freshly roasted beans still contain a lot of carbon dioxide inside, so the water flow and aroma during brewing may not be stable enough; after resting for a few days, the floral notes, fruit acidity, and sweetness will gradually become clearer. For beginners, choosing fresh beans is only the starting point, [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…]

Freshly roasted single-origin coffee beans are filled with a large amount of carbon dioxide inside. If they are ground and brewed immediately, the intense degassing reaction will form many bubbles in the coffee bed, preventing the hot water from fully contacting the coffee grounds. Giving the beans a period of steady resting time allows the gas to escape slowly, so that the internal aromatic compounds can be released during extraction. [more…]

Yirgacheffe SOE is often expected to have a bright aroma, but a bag of beans will undergo continuous changes in flavor from the moment it is roasted to the moment it is tasted. Freshly roasted coffee contains more carbon dioxide, and the aroma is easily held up by the gas; during extraction, there may also be sharp acidity, channeling, or excessive foam. Keep track of the purchase date, resting time, and how quickly the bag is opened. [more…]

Coffee beans aren't necessarily more fragrant the closer they are to the roaster. Freshly roasted beans continue to release carbon dioxide, making it harder for water to evenly penetrate the coffee bed during brewing, and the aroma may also seem loose and scattered. Whether a blend or an SOE tastes better often depends on whether they've reached their optimal drinking window, and whether a bag of beans can be finished in time after the flavors have opened up. [more…]

Roasted coffee beans accumulate a large amount of carbon dioxide inside, and these gases are slowly released outward over time. For home espresso extraction, the gas state inside the bean directly affects how smoothly water flows through the coffee bed. Freshly roasted beans are often full of internal pressure, and during pressurized extraction they tend to produce a rough and [more…]

The aroma of coffee beans isn't fully developed on the day they're roasted. After SOE is bagged, it continues to release carbon dioxide; in the first few days it smells very lively, yet during extraction it may expand too quickly and the flow rate can be erratic. Understanding the relationship between the roast date, the opening date, and the drinking timeline is more important than just looking at the shelf life in determining whether the cup is clear and sweet. [more…]

Before putting coffee beans into an espresso machine, the roast date is worth checking before the aroma words on the packaging. Freshly roasted beans are still rapidly releasing carbon dioxide, and after grinding, the coffee bed is easily disturbed by the gas, which also causes fluctuations in the espresso flow rate and crema condition. Allow an appropriate resting period, and then plan to finish a bag of beans during its peak flavor stage, usually [more…]

The aroma of coffee beans does not decline in a straight line from the moment roasting ends. Fresh out of the roaster, the beans are rich in carbon dioxide; when ground, they smell lively, but during brewing the degassing may be too vigorous, making it hard for water to penetrate the coffee bed evenly. After a few days, as the gas gradually escapes, the floral notes, fruity sweetness, and finish actually unfold more easily. Therefore, roasting [more…]

The hazelnut-colored foam on the surface of an espresso is often fuller at a certain period after roasting is completed. If the beans are put on the machine too early, the gas releases too quickly, the foam may be coarse and mottled in color, and the flow rate is also difficult to control; if left too long, the carbon dioxide decreases, and the crema layer becomes thinner. If you want to drink fine, dense crema, when choosing beans, besides looking at the blend [more…]

Front Street uses the "Front Street Classic Italian Blend" to make espresso. The baristas at Front Street Coffee (FrontStreet Coffee) will first dial in the extraction parameters for the espresso before they officially begin serving. Front Street uses a double-shot basket capacity, with a dose of approximately 18–20 grams. [more…]

Many friends who have drunk red wine should be all too familiar with one step in wine tasting: decanting. After a period of decanting, the astringency of the tannins weakens slightly, and the sweet and sour notes in the red wine become more lively. Drinking coffee is actually quite similar to drinking red wine—red wine needs decanting, while coffee beans need resting. [more…]

The color, aroma, and taste of coffee originate from a series of complex chemical reactions during the roasting process. Only when the essential components of green beans reach a balanced state can a good cup of coffee be achieved. This article will analyze the constituent elements of coffee quality from four dimensions: aroma, bitterness, acidity, body, and sweetness, and share how to savor coffee through temperature, portion size, and concentration. Finally, we will also explore coffee bean choices for different taste preferences, including moderate, intense, mild, and minimalist, helping you find the cup that suits you best among brands like Front Street Coffee. [more…]

Introduction: Dirty coffee burst onto the scene a few years ago, converting many latte loyalists into Dirty devotees. Unlike iced latte, Dirty coffee offers a visual and taste-bud double delight as you watch the espresso and milk create a gradient effect, and with one sip you go from rich coffee to sweet milk. [more…]

The transformation of a bean from light roast to dark roast takes only a few short minutes to complete, with a temperature difference of just about 10°C, yet the flavor and aroma undergo earth-shattering changes. Light roast refers to beans dropped during the period from the middle of first crack to just after the end of first crack! At this point, the beans, because within their bodies [more…]

Starting the workday with a cup of coffee has become a habit for many friends. With the development of the coffee industry, more and more novel coffee processing methods have emerged. In addition to the diversity of processing methods, the segmentation of coffee categories is also increasing. For example, what Front Street Coffee is going to introduce today is one of the more special ones. [more…]

SOE beans need to go through a degassing process from the completion of roasting to the unfolding of flavor. Freshly roasted beans contain a lot of carbon dioxide, so when brewing, the contact between water and coffee grounds can be uneven, and the aroma may also seem closed off; after proper resting, the acidity, sweetness, floral notes, and finish will gradually come together. Therefore, the closer the date does not necessarily mean the cup [more…]
