Use a roaster (hand-operated, electric, large machine) to roast raw coffee beans. Let me explain the usage of hand-operated (most commonly used at home). Shake the handle evenly and slowly, shake it quickly after hearing the blasting sound, until the fire is turned off 2 minutes after hearing the second blasting sound, and then shake it for 2 minutes.

Freshly roasted coffee beans will be bitter and release a lot of carbon dioxide, which needs to be put in a closed container for 7 days before they can be used.

After 7 days, the coffee beans have finished breathing and matured, and can be ground into powder to make coffee.

There are many kinds of coffee.

Automatic coffee machine-everything tastes the same.

Siphon pot-high technical requirements

moka pot

Hand-washed pot

Drip filter pot

Ice dripper (for authentic iced coffee)

Semiautomatic italian coffee machine

Automatic italian coffee machine

General household is mostly automatic coffee machine, siphon pot and mocha pot.

If you have any questions, you can ask me.
