View Full Version : when rehydrating the yeast, should it clump together?

I was trying to make my first batch of mead this weekend and when I got to the rehydrate the yeast step, i poured 2 5g packs into 100 mL of water. The yeast all started to clump together. Is this supposed to happen?

It's not the best of circumstances since that clump of yeast will not rehydrate as quickly as it should. The best way I've found to deal with yeast clumps during rehydration is to swirl the hydration vessel (I use a stoppered erlenmeyer chemistry flask, but a glass jar is also fine) a couple of times during the rehydration interval to ensure that all the yeast gets equally dispersed. I will typically swirl once just after I add the yeast, and again after about 5 minutes have elapsed, to maximize the amount of yeast that gets suspended in the liquid.
