Once I went to a good friend's house to play. As soon as I entered the door, I found that her house had a hand grinder. I was excited and asked if I could grind coffee powder? She said enthusiastically that of course. I'm really excited. I've drunk coffee before, but it's all instant coffee. I've never experienced hand grinding coffee. It's really a good opportunity to experience it.
My friend added some coffee beans into it. I looked curiously at the coffee machine and began to grind it. It was about 20cm tall, brownish black, with an open top and a rotatable handle in the middle. It began to grind. My friend held the machine for me, and I rotated the handle. It was very difficult. Maybe it was because the coffee beans were too hard. While I was grinding hard, my friend introduced that the coffee ground by hand was the most delicious. Indeed, during the grinding process, the coffee beans emit a strong fragrance, with a slightly bitter taste.
I breathe deeply, and it really smells good. With our efforts, coffee beans finally became coffee powder. I had a lot of fun, and I grinned a little, packed it and took it home.My friend brought me a coffee bag containing coffee powder. She introduced this bag to me, but it was different from ordinary bags. It had a one-way degassing valve.
