Craft beer equipment can brew high-quality beer, but there are still some issues to be aware of when using beer equipment. Therefore, if you want to brew high-quality craft beer, you need to pay attention to a lot of details. So what should be paid attention to when using craft beer equipment to brew high-quality beer?
1. Wort ingredients
The wort contains sufficient base acids and fermentable carbohydrates, because only a small amount of alcohol is produced through the synthesis system. If it is too large, adding more sucrose often leads to the lack of a group in the wheat meter, resulting in an increase in alcohol.
2. The amount of yeast added
It is appropriate to take (1.5~1.8)×17 pieces/mL. When the inoculation amount is high, the newly proliferated yeast cells are relatively small, which is conducive to reducing the formation of alcohol; if the yeast cells multiply, it is easy to form more alcohol. In actual production, the proliferation number of yeast is generally controlled within 4.
3. Fermentation
Using combined tank fermentation (main fermentation uses conical tank fermentation, and post-fermentation is carried out in traditional fermentation tanks), the total amount of alcohol increases by 2~25 compared with ordinary fermentation methods. Regardless of the method adopted, all measures to speed up the main fermentation will increase the alcohol content.
4. Fermentation temperature
Excessive dissolved oxygen in the wort and high temperature fermentation both promote the reproduction of yeast, and also increase the production of alcohol accordingly, so the process measures of low temperature main fermentation and high temperature reduction can be adopted. Pressurized fermentation is also beneficial in reducing alcohol formation.
