Changes in chromaticity
During fermentation, the color of the wort decreases.
The reason for the decrease is that, due to the change of pH value, the pigment material originally dissolved in the wort is condensed out again, and exists in the foam cover with protein, hop resin and other substances;
The second reason is that due to the reduction of tannins by yeast. In addition,the extent of wort chroma reduction is related to wort color. Those with high chroma have a large reduction range; those with low chroma have a small reduction range.

Changes in bitter substances
Formation of calcium oxalate
Oxalic acid is an intermediate product of sugar metabolism. During the fermentation process, calcium oxalate is precipitated from the liquor and attached to the yeast and fermentation container in the form of crystals. It is the main component of “beer stone”.

Advantages of Cylindrical Conical Tanks
- The cylindrical conical tank is taller, and it is easy to produce a gradient of carbon dioxide that varies from top to bottom, which can make the fermentation liquid form bottom-up or top-down convection.The higher the tank, the greater the convection speed, so the carbon dioxide dissolves better, and the beer foam is particularly fine and smooth.
- The cylindrical conical tank is suitable for both fermentation below and above fermentation.
- It can be cleaned automatically, the sterilization is more thorough, and the chance of contamination by miscellaneous bacteria is less, which is conducive to aseptic operation, which not only saves costs, but also reduces labor intensity.
- Since the cylindrical conical tank is pressurized and sealed for fermentation, the loss of bitterness of hops is reduced, so the amount of hops used can be reduced by about 15%.
- The washing device and the washing process generally use a spray head with washing liquid installed in the top of the tank, and through the reaction force of the washing liquid spray to promote the washing liquid to flush to the inner wall of the tank. In order to clean the tank, before cleaning, remove all the accessories that can be removed in the tank, clean and sterilize separately.
Hygienic of the process
- All the hoses for conveying materials must be sterilized with steam for 30~40 minutes before use, and the connection ports should be sterilized with alcohol cotton. After use, rinse the residues in the pipes with water for reuse;
- The fermentation tank must be brushed and sterilized after each use;
- Keep the ground and walls clean and hygienic to prevent the growth of bacteria;
- Escherichia coli shall not be detected in wort and fermentation broth.
Detection of fermentation broth
- Foam shape: For light beer, the foam should be white and smooth, and have lasting tear of beer.
- Aroma and taste: For light beer, it should have obvious hop aroma, pure taste, refreshing, harmonious beer body, soft, , no odor or smell; for Stout and dark beers, it should has obvious malt aroma, pure taste, refreshing, mellow, soft, strong taste, no peculiar smell.
- hroma Beer chroma is the depth of the color of the beer, which is mainly determined by the malting process, but it is also related to the mashing and fermentation process, and is one of the routine testing items for beer.
- Alcohol content, original wort concentration
