Hi all, decided to batch sparge my next brew tommorrow and been looking at the calculator and am a little confused about the top up water, when it says 12.5 litres for mash and 5.2 top up water does this mean mash with 12.5 ltr for 90 mins then add the top up before the first runnings, and at what temp should the top up water be.
