Come to Yunnan to enjoy a slow life and a quiet afternoon accompanied by coffee and books in the sun

To travel to Yunnan, no matter how many days you plan, urgent or slow, please slow down your pace and do as the Romans do and live slowly like the people of Yunnan.

General knowledge of coffee bean baking equipment and roasting theory of coffee beans

In addition to the degree of baking is divided into factions, even the roaster also has a family view. At present, there are two major professional roasters, one is the traditional rolling furnace (Drum Roaster), and the other is the newly developed hot gas furnace (Air Roaster). The former is heated by gas across the bottom of the furnace, while the metal blades in the furnace keep stirring the beans, while the latter bakes the beans with high-temperature hot air flow.

Hand-made coffee-- questions and answers on flannel filter cloth

Today, I use French blue velvet filter cloth to make Brazilian Syrador. I make a cup of water at a temperature of about 85 to 88 and a particle size of 3.5 in a small, medium-sized way. 2 flat tablespoons, but found that the coffee tastes strange ~ no acidity and sweet taste, a mediocre feeling, like a breeze with no special coffee flavor. So I decided to use the filter paper to make a cup in my hand and found that the smell came out.
