The Basic Changes When Wort Boiling

Depending on the process requirements, the wort after dilution needs to be boiled for 1-2 hours, while a certain amount of hops is added. Bitter and aroma substances can be dissolved into the wort by boiling, thus giving the beer a refreshing bitterness and a pleasant aroma. The wort after boiling is called the final wort.

The changes during the wort boiling process are as follows.
1) Dissolution and conversion of bittering substances from hops.
2) Formation and separation of solidifiable protein-complex polyphenols.
3) Evaporation of excess water to bring the wort to the required consistency.
4) Sterilization of the wort.
5) Absolute destruction of enzyme activity and solid wort composition.
6) The color of wort increases.
7) Increase of wort acidity.
8) Formation of reducing substances
9) Change in DMS content.
