How should coffee beans be roasted

One or two days.

Coffee beans fried with hand filter roasting tools can be stored at room temperature if they are to be used up within a week; if not, the best way to preserve them is to seal them in the refrigerator. Each time you use it, just take out the necessary amount and grind it into pieces. It takes about two weeks to maintain the inherent flavor of coffee beans.

A filter with a handle can be bought at a hardware store or a coffee shop. The raw coffee beans to be prepared are more suitable for beginners in Central and South America (Peru, Cuba, Mexico, Brazil, etc.). Pick out the defective beans by hand.

Put the beans into a filter with a handle and close the lid. Keep a certain amount of heat on medium heat, turn it into a circle and swing repeatedly, making the water evaporate. Hand filter baking carefully let the fire bake to every corner of the filter, and be careful not to scorch the beans, but concentrate on swinging the filter. After water evaporates, pay attention to smoke, color, fragrance and sound.

When the bursting sound of Battles goes off for ten to fifteen minutes, when the sound is still, there will be a second burst that lasts for fifteen to twenty minutes. As the status and types of coffee beans are different, the end can be judged by color and sound.

After pouring into the plate or basket, use the cold air of the fan or hairdryer to cool it quickly. After the fried test, the coffee beans will be reduced, leaving only about 85 grams.

Taste it (cup test) to see if the degree of frying is appropriate. At this time, it is the most tense and happy time. Let's try some delicious coffee made by ourselves.

Note: during roasting, there will be thick smoke and fragrance, and the skin of coffee beans will bounce off everywhere. Therefore, the gas stove should be covered with aluminum foil in advance, and the portable gas stove can also enjoy the fun of frying coffee beans outdoors.
