1: rolling.
Although crushing is a simple mechanical process, the degree of crushing is very important to the biochemical changes of saccharification, the composition of wort, the filtration speed of wort, raw materials and utilization rate.
2. Gelatinization and saccharification.
Gelatinization is to crush rice, put it in a flowerpot and add warm water. At a certain temperature (45℃), starch swells and splits into a uniform paste-like solution in water to make a completely liquefied liquid, which is malted with it in a saccharifying pot.
3: wort filtration.
After saccharification, the mercury in the saccharified liquid is sent to a filter, and the wort is separated from maltose to obtain clear wort.
4: Boil at high temperature and add hops.
Convey wort to wort boiling pot, add hops and boil for 65438 0 hours, so that the components of wort are stable, and the aroma, bitterness and various effective components of hops are dissolved in wort.
5: Clarification and cooling.
The wort is cooled in a cooler, and when it is cooled to about 65438 00℃, various beer yeasts are fermented.
6: Add yeast for fermentation.
After the wort is cooled, beer yeast and sterile air are added, and the wort is transported to the fermentation tank to start fermentation. Fermentation mainly uses beer yeast to convert maltose in wort into carbon dioxide and produce various flavor substances. After a certain fermentation period, it becomes a mature fermentation broth, also known as "tender beer".
7: Diatom filtration.
After the fermentation is mature, the yeast and macromolecular protein in the fermentation broth are removed by centrifugation and multiple filtration to become crystal clear alcohol, which can be canned after sterilization to make mature beer.
8: Packaging finished products.
In order to maintain the quality of beer and reduce the influence of ultraviolet rays, brown or dark green glass bottles are generally used. Empty bottles are soaked in a bottle soaking tank (alkali solution 2 ~ 5%, 40 ~ 70℃), then washed by a bottle washer, filled with beer by a filling machine, and capped by a capping machine.
Brewing beer is a famous technology that has been circulated for thousands of years. Related brewing knowledge can be found in many places, whether in books or online. The above are some basic general processes. Each craft beer has its own unique fermentation and brewing process, but for most people, the knowledge of brewing is not the most troublesome place, but it takes a lot of energy to obtain materials and props, hoping to help you.
