Behind the origin of the sour taste of coffee and the sour taste of coffee is a very complicated problem.

Raw coffee beans contain sour ingredients such as citric acid, malic acid, quinic acid and phosphoric acid, but these are not the main sources of sour taste when drinking coffee. The acid produced during baking is the main source of sour taste. Raw beans produce a series of chemical reactions during baking to form new acids. The most important thing is that chlorogenic acid is decomposed to form quinic acid and oligosaccharides.

Collect some data and opinions of the roaster.

1. First of all, I feel that the most important part of the coffee machine is to solve the drum problem. The first one in the picture above is the alp drum, which should be evenly stirred, but it is very troublesome for us to design this kind of design. The second is hottop's drum, which feels that the baking of small grams is very good, especially the middle slide can not only stir beans from separate parts, but also be good.

The thinking mode of extraction 2b-extraction time is transferred from Douban

Continuing with the previous article, http://www.douban.com/note/244706236/ extraction time looks easy, but it's actually a little more complicated than I thought.

We still return to the original two purposes, get the reasonable extraction rate and get the proper concentration.
