After coffee beans are roasted, a large amount of carbon dioxide gas accumulates inside the beans, and this gas is slowly released over time. When extracting espresso, overly active gas can hinder uniform contact between the water flow and the coffee grounds, which can easily lead to channeling during extraction or excessively coarse foam. Understanding [more…]

The appeal of coffees with notes of nuts, cocoa, and caramel often lies in their consistent sweetness, mild acidity, and smooth entry on the palate, making them suitable for hot Americanos, milk-based coffees, or moka pot brews. However, the same bag of beans, when drunk at different times after roasting, will vary in aroma, body, and finish. When choosing this type of coffee, besides looking at the flavor description, also pay attention to the roast [more…]

Freshly roasted coffee beans are filled with carbon dioxide internally. When making a latte, the state of gas release directly affects extraction efficiency and the degree of integration with the milk. Understanding the degassing process of coffee beans at different stages helps us taste a balanced and full-bodied coffee flavor during the phase when aromatic compounds are most active. The initial period after roasting is [more…]

Yirgacheffe is often remembered as a coffee with floral notes, citrus, and a bright tea-like quality, but these descriptions are not fixed labels. From the moment roasting is completed to the moment it is sipped, coffee beans go through degassing, aroma development, and flavor decay. Seeing this curve of change clearly can help us judge the condition of a bag of beans and also provide a basis for identifying origin information. [more…]

Until recent years, all coffee beans were packaged in burlap sacks and transported in shipping containers, only reaching roasters several months after the beans had been processed. If roasters and importers occasionally wanted to cup coffee beans from the place of origin, or taste a "pre-shipment sample," what they received instead would be stored [more…]

Freezing is a very popular method of "preserving" coffee beans in recent years. Simply seal the coffee beans and toss them into the freezer, and the flavor loss of the coffee will slow down, thus extending its shelf life. Many friends have adopted this method to stock up on coffee beans purchased during Front Street Coffee's discount events. [more…]

Freshly roasted coffee beans have accumulated a large amount of carbon dioxide inside, and at this point the bean structure is tight and the aromatic compounds have not yet fully unfurled. If brewed immediately after roasting, the violently released gas can easily prevent hot water from evenly penetrating the coffee grounds, often making the extracted coffee taste thin or sour. Give the coffee beans a [more…]

Darker-roasted coffee beans undergo full caramelization and Maillard reactions in the roaster; the fibrous structure inside the bean expands, creating larger pores, and the degree of gas saturation and the rate of release are noticeably faster than in light roasts. Understanding the degassing patterns and flavor evolution of dark-roasted beans helps you accurately gauge the bean's condition during everyday pour-over brewing, allowing [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…]

After coffee beans are roasted, they continue to release a large amount of carbon dioxide gas internally. In the pressurized extraction environment of a fully automatic coffee machine, the state of gas release directly affects the contact between water and coffee grounds. Understanding the degassing patterns of coffee beans and the resting period helps the machine extract a more [more…]

The flavor of dark-roasted coffee beans is built on the sweet-bitter balance brought about by caramelization and the Maillard reaction, and this part of the flavor is relatively overt, and also more dependent on proper storage. The darker the roast, the more porous the bean body, the more easily aromatic compounds escape, and the faster the oils are exposed to the air. Mastering a few key storage points can keep a [more…]

How much of an impact does the freshness of coffee beans really have on flavor? Through comparative observation and roasting cupping of four washed Yirgacheffe G2 green beans, this article analyzes one by one the key role of freshness in coffee quality, from green bean color and dehydration state to post-roast aroma and mouthfeel layers. The test used the same roasting curve and repeatedly evaluated the coffee by pour-over and immersion methods, ultimately finding that Sample A and Sample B formed a striking polarity—the former had prominent floral and fruity notes and a long, sweet finish, while the latter lacked vitality due to aging. Whether green beans or roasted beans, freshness is the core element that determines the soul of coffee, and Front Street Coffee has always emphasized the importance of storage conditions. [more…]
