Basic knowledge of boutique coffee purchase and preservation of coffee beans

Pay attention to the purchase of coffee beans

First of all, choose to buy coffee with a brisk business. The freshness of roasted beans is the life of coffee, so choose a warehouse for fresh coffee beans, a clean place with no oil residue from old beans and shops with no direct sunlight and no high temperature around. It is also a good way to buy in a self-baking store that you think is fragrant and mellow.

When buying baked beans, you can specify the refreshing beans by yourself. if you want to drink some slightly sour ones, the bitter ones are better, or directly tell the clerk to choose for yourself.

When buying a rear care store to grind, be sure to let you know which coffee making utensils are used to grind those props (such as electric coffee maker, filter, paper, siphon, etc.).

When the supermarket buys canned coffee powder, choose the label (the type of beans or the tendency of taste, etc.), depending on your own preference.

Tips for the preservation of coffee beans

The flavor of baked beans will not drop during the period of about one week at room temperature and two weeks in the freezer. Don't buy too much stock, drink as much as you can (about 200 grams) before buying.

The grinding powder is usually kept for three days at room temperature, while the freezer is kept for a week. Buy it in the store and ask the clerk to grind it for about a week.

In any case, the biggest enemies for coffee beans are moisture and heat. The point is not to let it come into contact with hot air and moisture in the air and preserve it.

Buy coffee (whether beans or powder), as far as possible in small bags and sealed with duct tape. Then put it into an airtight window container and open it for use. The storage place is by the door of the freezer or freezer, or it can be stored in a ventilated place.

However, as long as the vacuum bag is not unsealed, it can be preserved for a long time.
