Grain bill / water ratio

[BeerJ]

Hi guys,

I have bought a few all grain kits lately that have no water quantity’s on. I’ve been guessing from previous expierence and brews the split between mash and sparge water.
My question is is there a formula you use that can tell you how much mash water you need using a given grain bill size.

thanks

I use a 3.5:1 ratio mainly so 5kg of grain I use 18 litres of water. I then sparge with 14 litres

I use 3L per kg of grain. I think though some of the answer will depend on what works best on your system and gives you the best efficiency. Also the maximum capacity of your mash tun could be a limiting factor depending on how big it is. Some people prefer a wetter mash to aid recirculation, stirring etc. You will hit on what works for you with a bit of trial and error.
