Why is rehydrating the dry yeast before pitching important?
Dry beer yeast needs to be reconstituted in a gentle way. During rehydration the cell membrane undergoes changes which can be lethal to yeast. In order to reconstitute the yeast as gently as possible (and minimize/avoid any damage) yeast producers developed specific rehydration procedures. Although most dry beer yeast will work if pitched directly into wort, it is recommended to follow the rehydration instructions to insure the optimum performance of the yeast.
这里有提到，活化过程有可能给酵母造成致命伤害。
我干投过几次，到现在没出现过问题。也活化了几次，这是唯一有问题的一次。当做一个经验吧 |
