High-quality coffee beans introduce the selection of coffee cooked beans, the maintenance of coffee beans, the roasting of coffee beans

After the coffee beans are roasted, the oxidation and aroma volatilization are irreversible. So coffee lovers have always been meticulous about the preservation of beans. This article mainly analyzes the preservation of cooked beans. I hope it will be helpful to you.

one。 What is raised beans (single product)

Freshly roasted coffee beans can not be fully released because of too much carbon dioxide, so they are tasteless. So beans are not as fresh as possible, it takes a period of time to "exhaust", we also call beans, most of the single beans can be drunk after 24 hours, if the baking is relatively shallow, you can drink for one more day.

two。 The best flavor period

The period of drinking after the completion of the cultivation of beans (about 24-48 hours) until obvious defective flavor appears is called the best flavor period. Take moderately baked beans as an example, the best flavor period is about 30 days. If it is light baking, it is about 40-50 days, while the best flavor period of deep baking is short, usually less than 30 days.

The best flavor period mentioned above is established under certain preservation conditions, that is, the three key factors for the preservation of ripe beans: sealing, protection from light and moisture.

Most of the coffee beans bought by beginners in stores or online have exceeded the best flavor period, so the player circle has always scoffed at bulk commercial beans and imported brands. It is often the business that buys baking in recent days or bakes after placing an order to ensure that the beans are received as fresh as possible.

three。 A bag of coffee and cooked beans

Most of them are one-way exhaust valve bags lined with aluminum foil. Aluminum foil can block light and air. The function of the one-way exhaust valve is to discharge too much carbon dioxide so that the bag will not burst without opening.

The bag is useless when you get the coffee beans. Because once the bean cultivation is completed, there is no need to let it exhaust again. When you press the exhaust valve around the smell of coffee, in addition to carbon dioxide, there are many fragrances are also discharged and lost. So changing the seal of the container is the first step, and when you want to drink coffee and open the lid, you will complete the exhaust.

For example, we use Kraft paper aluminum foil bags with one-way exhaust valves and seals that can be used repeatedly, but this kind of packaging is not suitable for long-term preservation of cooked beans. So the jar of one-way exhaust valve is also not recommended.
