Many experienced beer brewers believe that yeast fermentation is a very important factor in determining the quality of beer. Today, ZHcraft beer equipmentmanufacturers are talking about what environment is suitable for yeast fermentation?

①Temperature, high temperature fermentation will bring bad flavor to beer, and fermentation process below the optimum temperature of yeast fermentation will slow down and also bring peculiar smell. We know that the general fermentation temperature of Aier yeast is between 18°C-21°C, and the Lager fermentation temperature is between 10°C-13°C (the actual fermentation temperature is subject to the recipe and yeast instructions!), and at the same time We need to pay attention to the fact that the wort temperature of the yeast will rise by 1°C-2°C during the fermentation stage, so the temperature at which we inoculate the yeast is 1°C-2°C below the fermentation temperature, and then let the fermentation heat up naturally.

②Yeast nutrient, whole malt brewing beer, wort contains almost all the nutrients needed by yeast, except for Zn, which cannot be provided by wort, so we need to supplement yeast nutrient. At the same time, some low-concentration beers need to be supplemented with yeast nutrients due to insufficient nitrogen sources.

③Oxygenation, this may be a tangled process for novices. Most people will ignore this process, or simply forget. Some people feel that oxygenation will oxidize the wort. This is a misunderstanding. When the wort temperature is lower than 26.7°C, the wort will not be oxidized when exposed to oxygen, and this stage is the only time when the wort can be exposed to oxygen during the entire brewing process.

The method of oxygenation pump + filter + bubble stone can be used to fill the wort with finely divided sterile air, or it can be filled with medical oxygen (not recommended, oxygen has strong oxidizing properties! High risk, especially contaminated with oil There is a risk of explosion when operating the oxygen cylinder by hand!). If you don't have the above equipment, you can also use two fermenting barrels to pour the wort back and forth. On the one hand, it helps to continue to cool down, and on the other hand, the wort is exposed to oxygen in a larger area. Good oxygenation can help yeasts to reproduce healthily. Insufficient wort oxygen will cause slow fermentation start and insufficient fermentation will produce peculiar smell.
