Some claim that the mash process creates all the nutrients necessary for good fermentation. Others claim that adding yeast nutrient such as 1/2 teaspoon of wyeast yeast nutrient or some other zinc addition makes for a better fermentation and better beer particularly when brewing with RO water. Has anyone done side by side experiments to prove this one way or another?
