In the process of pour-over coffee, blooming is a step that seems simple yet contains a wealth of information. Many enthusiasts are accustomed to judging whether coffee beans are fresh by observing the extent to which the coffee bed puffs up during blooming—the larger the puff, the fresher; the smaller, the staler. However, Front Street wants to tell everyone today that bean freshness is not the only factor affecting the size of the puff. This article will start from the working principles of blooming and deeply analyze why the coffee bed expands, as well as what variables besides freshness can lead to differences in the puff. At the same time, we will also explore how the process of carbon dioxide release after coffee beans are roasted affects extraction, helping you understand the blooming phenomenon more accurately in your daily brewing.

The coffee bean bag you brought home is bulging—is it spoiled or is this normal? Many coffee lovers have encountered this question. In fact, a swollen coffee bag doesn't necessarily mean the beans have gone bad—roasted coffee beans continuously release carbon dioxide, which is the main reason the packaging expands. However, not all swollen bags are harmless; if accompanied by a musty or sour odor, that's a different story. This article will walk you through the chemistry of coffee bean degassing, the mechanism of one-way degassing valves, and why dark-roasted beans are more likely to make packaging bulge, helping you accurately judge whether the coffee beans in your hands are still safe to enjoy.

Tims, a Canadian coffee chain brand that has been in the Chinese market for five years, recently celebrated its 60th birthday. To mark the occasion, Tims launched a six-week promotion offering 9.9 yuan deals every week, along with a campaign where purchasing designated set meals would earn a limited-edition 60th-anniversary themed ceramic cup.

Brand CEO Lu Yongchen once said the company would accelerate upgrades centered on user needs. Judging from the feedback on this anniversary gift, Tims still has room for improvement in peripheral product quality control and experience. [more…]

The bag of coffee beans you just bought is bulging—is it spoiled? Can you still drink it? Actually, the reasons for coffee bean bag swelling are quite different from those for ordinary food.
