Many friends may find espresso very bitter the first time they try it, but gradually, you'll come to sense the rich aroma and full-bodied depth of espresso's original flavor—something other cof [more…]

By splitting the extracted espresso into 2~3 portions, then separately crafting each into a different type of coffee and finally combining them for service, this is a very popular serving format in coffee shops today—Coffee combo. Because you can simultaneously taste different "dishes" made from a single bean [more…]

In the cold brew world, blending is a popular trend—mixing two or three beans in certain proportions and steeping them together. The flavors complement each other, creating layers that a single bean can't deliver. With hot pour-over, blends tend to clash, but cold brew's low-temperature extraction is much gentler, allowing beans to meld together seamlessly—making it easy for beginners too. If you're tired of single-origin beans and want to explore something new [more…]

Whether the aroma of coffee beans can cut through milk in a latte depends not only on the beans themselves but also on how many days have passed since roasting. Freshly roasted beans are still rapidly releasing carbon dioxide, which can cause uneven espresso flow and coarser foam; leave them too long, and the nutty, caramel, or fruity notes gradually fade. Catching that middle window of peak condition, [more…]

After coffee beans leave the roaster, their flavor does not settle immediately. The beans continue to release carbon dioxide; when freshly roasted beans are used to make espresso, the puck is easily disturbed by the gas, making flow rate and extraction uniformity harder to stabilize. So-called freshness does not mean the closer to the roasting moment the better, but rather allowing aroma liveliness, degassing state, and [more…]

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…]

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…]

With the development of specialty coffee, more and more people are falling in love with single-origin coffee. Two types of coffee have emerged on the market: single-origin coffee beans and blended coffee beans. Single-origin coffee beans are generally used for making pour-over coffee, though many specialty coffee shops also use single-origin coffee beans to make espresso. Blended coffee beans [more…]

The flavor profile of commercial coffee beans evolves continuously over time; the moment they finish roasting is not when they immediately reach their ideal flavor. After being heated, the interior of the bean traps a large amount of carbon dioxide, and this gas continues to be released outward over the first few days. Understanding the degassing and maturation process helps us more calmly plan each [more…]

A highly sweet Americano often does not show its full expression on the very day of roasting. When coffee beans have just left the roaster, they are still degassing heavily; excessive carbon dioxide makes the espresso fluctuate more and causes the aromas to mask one another. Scheduling the bag-opening date for the stage when the flavor gradually unfolds allows the fructose-like roundness, clean finish, and aromatic distinctiveness to be more easily [more…]

Coffee beans just out of the roaster won't display their full flavor the moment they go into the espresso machine. They still hold a lot of carbon dioxide inside, and during pressure extraction this can make the water flow and crema behave erratically, while the aroma in the cup may also seem shut down. Give the beans a quiet period to degas, and the sweetness, body, and finish of the espresso will usually be more [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…]

Yirgacheffe's characteristic floral, citrus, and tea notes depend heavily on the time between when the beans finish roasting and when they're brewed. When buying beans, don't just focus on a few words on the flavor card—also check the roast date, the packaging method, and your own drinking speed. When the beans are in the right state, the aromas open up, and the acidity and sweetness show more layers. After roasting [more…]
