Can I mash it

[JammyBStard]

How do I work out if my 24L cooler box mash-tun Tun is big enough for 6.25kg of grain and 13.3L of water?

It is plenty big enough, but that's a very stiff mash and you will need to fly sparge rather than batch sparge.

There is a calculator here that I have found to be pretty darn accurate:

It's the 3rd one down.

Sorry, should have been 6.25kg of grain and 16.3L (2.6L/1KG)

Less than 21L then; should be fine. Thanks all
