To make delicious cold brew coffee, Front Street believes three things are essential: choosing floral and fruity coffee beans: since cold brew coffee is extracted at low temperature over a long period, more small-molecule substances in the coffee beans such as floral notes and fruit acids are extracted, while large-molecule substances such as tannic acid and other bitter compounds are difficult to extract.

Buffalo milk has long been a specialty dairy product in the Guangdong and Guangxi regions, and in recent years it has been increasingly used by coffee enthusiasts to pair with espresso. It contains higher levels of protein, fat, and calcium than regular milk, with a lower water content, making it sweeter and silkier to drink. So, is buffalo milk actually suitable for latte art?

Freshly roasted coffee beans internally contain a large amount of carbon dioxide. These gases are both an important source of the rich crema layer produced during extraction and, in the early stage, also hinder the even contact between water and flavor compounds. Just-roasted coffee beans need to go through a period of natural degassing, so that the aromatic oils and soluble components inside can gradually [more…]

The refreshing, sweet, or heavy character of cold brew coffee is closely tied to the roast level of the beans. Long, low-temperature extraction softens the acidity and accentuates the aroma and sweetness.

In the first few days after an espresso blend is roasted, the beans are still releasing carbon dioxide. If you pull a shot during this time, the puck is easily disturbed by the gas; the crema may look thick and rich, but the sip can taste loose and the aroma isn't fully focused. Planning together around the roast date, the expected opening date, and daily usage is often better than simply chasing freshly roasted beans [more…]

Coffee brewed with a moka pot is quite concentrated, and the condition of the beans directly affects how it tastes. Freshly roasted coffee beans are usually still releasing carbon dioxide; though the aroma may be punchy, the liquid can seem thin. After resting for a while, the sweetness, body, and finish gradually come together. When buying beans, besides looking at the flavor notes, also pay attention to the roast [more…]

Full-bodied mouthfeel is not a flavor that is fixed in place the moment coffee beans are freshly roasted. After the beans come out of the roaster, they continue to slowly release carbon dioxide internally, and the aroma, sweetness, and mouthfeel will shift over time. If brewed too early, the cup may have a noticeable gassy sensation; when left to the right stage, flavors such as nuts, cocoa, and caramel are more likely to connect. [more…]

Freshly roasted coffee beans are not immediately ready for brewing; they hold a large amount of carbon dioxide gas trapped inside from the high heat. This gas is slowly released over time, and during this process the aromatic compounds inside the beans gradually become active and move toward balance. Understanding how coffee beans evolve from degassing to aroma development helps me [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…]

When making espresso, the golden foam on the surface of the cup is greatly influenced by the freshness of the beans. Freshly roasted coffee beans contain more carbon dioxide, which is rapidly released when they meet high-pressure hot water, making the crema look richer and the aroma more punchy. However, more crema does not mean the flavor has matured; the time since opening the bag, the roast level, and the beans' own [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…]

Espresso blend beans begin a period of change from the moment roasting is complete: in the early stage they release a large amount of carbon dioxide, in the middle stage the aroma and extraction gradually open up, and in the latter stage they slowly lose their vibrancy. When beginners choose beans, they don't need to treat "the closer to the roast date, the better" as a rule; instead, they should let the dates of arrival, opening the bag, and finishing the beans fall within a suitable flavor window.

Freshness is not about being as close to the roast date as possible, but about the beans [more…]
