Can freshly roasted coffee beans or powder be boiled immediately? How does it taste?

For professional baristas, please follow the coffee workshop (Wechat official account cafe_style)

You can drink it, but it will be a little irritating.

Because during the roasting process of coffee beans, a large amount of carbon dioxide is produced inside the beans due to the thermal decomposition of carbohydrates, which is constantly released during the baking process, but part of the carbon dioxide is still left inside the beans after baking. In fact, it is beneficial, because after the beans are roasted, they will continue to release carbon dioxide, which helps to isolate oxygen, delay the oxidation of coffee beans, and keep the flavor of beans from being lost.

I usually have a cup test immediately after baking, but if I officially sell it to the customer, I still have to leave it open for about 12 hours.

If you are baking yourself, then put it for a while before drinking. If you buy it, ask the store when the pot will be baked. The professional question is: have you raised beans?

Freshly roasted coffee beans should be drunk immediately. After the coffee beans are roasted to brown, their shelf life has been very short, only a short period of 15 days. The aroma and taste of the coffee bean reached its peak a week after the coffee was roasted, and the taste began to decline after a week, and the fragrance disappeared after 15 days. So good coffee must be freshly roasted.

The freshness of roasted beans is the life of coffee. There are three steps to determine the freshness of coffee beans: smell, see and peel.

1. Smell

Put the coffee beans close to the nose and take a deep smell to see if you can clearly smell the aroma of the coffee beans. If so, it means the coffee beans are fresh enough.

On the contrary, if the aroma is weak, or if the smell has begun to appear greasy (such as peanuts or nuts will appear for a long time), the coffee beans are not fresh at all. No matter how much effort it takes to grind and boil such coffee beans, it is impossible to make a good cup of coffee.

2. Look

Spread the coffee beans on your hands, determine the origin and variety of coffee beans, and determine whether the coffee beans are roasted evenly.

3. Peeling

Take a coffee bean and try to peel it off by hand. if the coffee bean is fresh enough, it should be easy to pull away, and it will have a crisp sound and feeling. If the coffee beans are not fresh, you will find that it seems to take a lot of effort to get rid of a bean.

Another important point to observe when peeling off the coffee beans is to see if the firepower is uniform when baking. If it is uniform, the outer skin and inner layer of the beans should be the same color. If the color of the surface layer is obviously much darker than that of the inner layer, it means that there may be too much firepower during baking, which will also affect the aroma and flavor of coffee beans.
