To achieve good flavor, we should choose freshly roasted coffee beans—this is a consensus we reached long ago. Based on experience, when coffee beans are in the "too fresh" stage (0–2 days after roasting), we "rest" them, meaning leaving them untouched until they have degassed slightly before brewing and extracting, so that the coffee's flavor will [more…]

Have you ever had this experience: you buy coffee beans that have been roasted not long ago, can't wait to open them and brew a cup, only to find the extraction is very unstable and the flavor performance is less than ideal. A few days later, when you brew again, it tastes better. What is the reason for this? In this article, Front Street Coffee takes you through what "bean resting" means. Coffee beans [more…]

Coffee enthusiasts who often pick freshly roasted coffee beans at FrontStreet Coffee know that the optimal flavor period for coffee beans is within one month, while for drip bag coffee it is half a month; does this mean that just-roasted coffee beans are at their freshest? This [more…]

Freshly roasted coffee beans continue to release carbon dioxide accumulated inside them during the first few days, and this natural degassing process directly affects the extraction efficiency of hot water. If the beans are too full of internal gas, the hot water poured in is easily blocked by bubbles, making it difficult for aromatic compounds to dissolve fully and evenly into the water. Therefore, al [more…]

The floral and fruity aromas of coffee are not magic conjured by the roaster, but genes written into the terroir of the producing region and the processing method. Flip through the origin records of the mainstream floral and fruity bean varieties on the market, and you will find that behind every fruity note lies a traceable origin story. The opening volume of the records is Ethiopia. As coffee's [more…]

Friends who brew coffee with a moka pot almost always struggle with one question: how do you pick a bean that isn't sour? After all, coffee made in a moka pot is highly concentrated, so any sourness becomes very obvious once it appears. The good news is that as long as you stick to the directions of "full-bodied, low-acid, rich in oils," there are excellent choices from beginner to advanced levels. [more…]

Anaerobic natural, lactic fermentation, barrel-aged, yeast inoculation—the vocabulary of specialty coffee processing methods has exploded in recent years, and coffee menus increasingly read like a brewery's process manual. These experimental processing methods are not marketing coinages; each one corresponds to a genuine technological innovation. This article maps out the mainstream lineage and examines "flavor alchemy." [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…]

Decaffeination processing causes subtle changes to the cellular structure of green beans. After being heated during roasting, the pores inside the bean are often looser than those of regular beans, and the rhythm of degassing and flavor release is also more unique. If you want to taste clean, transparent fruity notes and sweetness from a pour-over brewer, understanding the freshness curve and degassing process of decaf coffee beans is [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…]

From the day roasting finishes, the aroma of coffee beans enters a track of continuous change. When SOE is pulled directly as espresso, if the gas inside the beans is still vigorous, the puck tends to extract unevenly, and the acidity in the cup is lively but somewhat scattered; as the beans gradually relax, sweetness, aroma, and texture come together more easily. Therefore, deciding whether to pull it as espresso, [more…]

Freshly roasted coffee beans are rich in carbon dioxide internally. Under the heat of a medium roast, a loose, porous structure forms, and these gases are gradually released over the following days. If you grind and brew the beans immediately after getting them, the vigorous bubbling of gas will hinder full contact between the water and the coffee grounds, leading to uneven extraction. [more…]

Freshly roasted coffee beans are filled with active carbon dioxide gas internally. During extraction, this gas creates resistance that prevents hot water from fully contacting the coffee grounds. For espresso extraction, excessive gas makes the crema appear coarse and dissipate quickly, while the flavor tends toward dryness. Allowing the roasted beans to [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…]

Many friends assume that freshly ground coffee means fresh coffee, but that's not actually the case. In reality, to truly enjoy the aroma of coffee, it's not just about grinding fresh—the roast time of the coffee beans also matters to some extent. Front Street Coffee has always placed great emphasis on the freshness of coffee beans, high [more…]

Some people drink coffee and only taste a "coffee" flavor, while others after just a couple of sips can casually say whether it's a nutty or floral coffee, and can even determine the coffee bean's origin and harvest season, leaving those around them [more…]

Mandheling coffee beans mainly exhibit a rich mouthfeel and a sweet, caramel-like flavor with a pleasant bitterness. Therefore, they are generally dark roasted. Taking Front Street's Golden Mandheling coffee beans as an example, before roasting Golden Mandheling, Front Street will roughly determine the roasting direction based on the growing information. The Golden Mandheling coffee beans are grown at an altitude of 1100–1 [more…]

"In the sixth to eighth centuries AD, Kaldi, a young Ethiopian goatherd, was tending his goats in a forested mountain area. Then one day, he noticed that his flock had suddenly become inexplicably excited, jumping and frolicking about. Even an old sick goat regained its vigor and was soon running briskly. After careful observation, he finally discovered that these 'symptoms' appeared after the flock ate from the forest [more…]
