For extra sanitary caution, boil the water first and then add your yeast to it when it is between 95F and 105F (this is the recommended rehydration temperature for US-05, if I remember correctly- don't quote me. Look that up, it may be different for your yeast- should be on the package). Rehydrating at an incorrect temperature completely defeats the purpose of rehydrating in the first place.
I can't be arsed to keep up this list of what's in the fermenters, but hey, check out the cool brewery I own!
