High-quality beer can be brewed by using craft beer equipment reasonably, but there are still some issues that need to be paid attention to when using beer equipment. So if you want to brew craft beer, you need to pay attention to a lot of details. The following will share with you some of the factors you should pay attention to when you want to brew high-quality beer.
1. Wort composition: The wort contains a sufficient amount of base acids and fermentable carbohydrates, because only a small amount of alcohol is produced through the synthesis system [the base acid content in wort is controlled at (18±2) mg/L. Appropriate. If the ratio of excipients is too large and too much sucrose is added, it often leads to the lack of a group in the wheat meter, resulting in an increase in alcohol.
2. The amount of yeast added: (1.5~1.8)X17/mL is suitable. High inoculation amount and relatively few newly proliferated yeast cells are beneficial to reduce the formation of alcohol; if the yeast cells multiply more, it is easy to form more alcohol: in actual production, the proliferation number of yeast is generally controlled within 4.
3. Fermentation type: Combined tank fermentation is adopted (the main fermentation uses conical tank fermentation, and the post-fermentation is carried out in traditional fermentation tanks), and 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: The high dissolved oxygen in the wort and the 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.
