Hello to all, I was doing a search here looking for opinions on sparge water temperature and noticed I was not doing it correctly. I batch sparge and this is what I have been doing as of last batch. I collect my first runnings from my mash, then fill my tun with 200 degree water to get to 170 degree grain bed \water, let sit for 30 minutes then collect runnings.The volume of water is the amount I need to make boil volume, so I am doing one sparge, what I have read here is that most people do two or more sparges. I always hit my numbers, as far as OG. What would be the advantage of splitting sparge into two or more sparges?
