I'm still practicing the simple stuff. I brewed a 2 gallon DME batch last night and for the first time, I re-hydrated the yeast instead of dry pitching.

I boiled some RO water in a pyrex cup in the microwave to sanitize the container. The hot water was then discarded and replaced with about a cup of Ozarka drinking water. Safale-04 was mixed with this at about 82 deg F and allowed to sit covered about 40 minutes with frequent stirring. The krauzen has taken off like a rocket at 6-8 hours. So I figure I either got it right or introduced some kind of go-getter contaminant.

Question after the fact: Is bottled water considered sanitary enough for dry yeast re-hydration? Boiling and then cooling down in time to pitch sounds like a real PITA.
My airlock passes gas.
