Hence the idea being to use it to rehydrate the yeast, then pitch the mix into the must, then once the lag phase is finished and there's signs of active fermentation (bubbles) you then add whichever main nutrients are being used....
Ok thanks, that makes sense. So there should not be any nutrients added until the fermentation starts? There are several recipes floating around that mention adding the nutrients prior to pitching. What you are saying is that this practice is incorrect and should be avoided?
