So I have only brewed one batch of beer and when I was chilling the wort I was stirring the wort with the chiller. Is this an ok thing to do? I mean it went from 212 down to 74 in about 6-7 min. Also i am making root beer no alcohol should i still boil it for an hour then chill it or just boil it and then chill to keg it? Also i am doing an extract, but the next time i will make it from scratch with roots and stuff. any advice is appreciated.
