alright here is the deal.i am seriously contemplating moving on to AG brewing and have decided that i want to batch sparge vs fly sparging.i have read a ton and watched videos on doing this and pretty much get it.step your grains for 1hr or so then add your first batch of sparge water to that ,mix and let it sit for 10 min or so.reciculate and then do your first run off.then add your second batch of water,mix well,but now here is my question.evreywhere i have looked nobody says how long they let it sit befor the second run off?other than that question i am doing this correct right?
