Many people have drunk coffee, but how many people know the real method of making coffee? Recently, I did nothing to find some articles about coffee brewing. After reading them, I realized that my understanding of coffee was quite superficial. Practice: (two persons) *

Pour boiling water 240c.c into a spherical beaker *

Wipe the water droplets on the outside and heat them with alcohol lamp *

Put 20g of coffee powder (the amount can be increased or decreased according to personal taste) in the refining cup *

After the boiling water at the bottom is completely boiled, turn the refining cup into a beaker and fix it *

When the boiling water rises to the refining cup, stir the coffee powder evenly with a bamboo scoop to completely release the ingredients of the coffee powder *

Turn off after about 20 to 30 seconds *

When the coffee in the refining cup flows down, you can take it off *

Eighty-seven degrees is an ideal drinking temperature. I almost forgot to mention in the article that this kind of brewing method needs attention, that is, try to avoid repeated brewing of coffee. Also, when the beaker is in high heat, it should avoid contact with cold water and cause rupture, and it should be noted that when there is no water or coffee in the cup, it should not be ignited and baked to prevent rupture. Finally, immediately after use, brew with lukewarm water or lemonade, and completely wash off the coffee oil, and air-dry it in the shade. Ha ha!
