So I've heard that if you add dead yeast it can serve as an nutrient for the rest but I read in an wikipedia article on stuck fermentation that "Once the fermentation is stuck, it is very difficult to restart due to a chemical compound released by dying yeast cells that inhibit the future growth of yeast cells in the batch."
So do dead yeast cells "sabotage" the rest?
