I tried making 3 yeast starters yesterday by boiling 1 Liter of water and adding 100 grams of DME per batch. These were for Wyeast smack packs which I did smack an hour prior to adding to the yeast starter. 1 of the 3 batches shows activity but how do I really know if the other 2 batches are going to be ok? I have strirred them gently every 2 hours and they have been mixed for 14 hours so far? Thus, how do I know if these yeast are viable?
Thanks
