Why do we have to bake coffee beans ourselves?

So why bake your own coffee beans?

1. Freshness brings the best flavor. Stale bread is not like stale coffee beans, the former cannot be eaten if it is not fresh, while the latter can still be drunk even if it has changed, and some people even enjoy it. Most people don't know how much coffee brewed from freshly roasted coffee beans will have an explosive taste with strong aroma, which can make people feel bright in front of their eyes, which is very different from the off-flavor coffee they usually drink. In fact, after the coffee beans are roasted, their flavor begins to decline sharply. The reason is that coffee beans themselves release carbon dioxide, preventing the invasion of oxidation, at the same time, volatile aromatic substances are also lost with carbon dioxide, and after the carbon dioxide emission period, the delicate coffee flavor oil will be oxidized and changed. So the best taste period for coffee beans is only two weeks after baking. Grinded coffee loses its aroma 50 times faster than whole coffee beans, losing it in a few hours or less. Just imagine how long will it take for a bag of imported coffee beans to cross the ocean from a roaster to a businessman and then to China? Therefore, only by roasting your own coffee can you maximize the freshness of the coffee. This is the minimum requirement for a good cup of coffee.

two。 Control the quality of coffee beans from the source. After the coffee beans are roasted, some of their own defects and shortcomings will be covered up, just like many deeply processed foods. Through coffee raw beans, we can distinguish their varieties, the refining methods of raw beans, fresh seasonal beans or old beans in previous years, defect rate, and even authenticity (inferior ones such as the famous Blue Mountain, etc.). Before baking, it is necessary to remove some impurities mixed in coffee beans, such as grass roots, leaves, stones and some defective beans such as moldy beans, worm-eaten beans, immature beans and so on. In this way, we can drink good coffee worthy of the name.

3. You can decide what kind of flavor you want. Coffee will show different flavor under different roasting degree, and the caffeine from different producing areas will have different characteristics due to the influence of soil, water, climate and other natural environment. Therefore, self-roasting coffee can bring different flavor and taste by mastering different roasting degrees. In this way, coffee can be customized according to its own characteristics or personal preferences.
