Mash tun too small for needed water
« on: May 04, 2008, 08:22:48 AM »
I have a 5 gal Igloo cooler (6-gal kettle) equipment set up.  When I make a heavy beer (12 lbs or more grain) how do I get all the water calculated to fit?  For example I have a recipe that calls for 23 lbs of grain.  The Single Infusion, Full Body mash calls for 28.75 quarts of water, which won't fit in the 5 gal cooler.  Is there a way to have the instructions split it in half and I do two (or more) mashes?

I think I'm just missing something.

Hi,
  One way to do it is to reduce the water to grain ratio in the mash schedule - it normally runs about 1.25, but I believe you can run it down to about 1.0 before the mash gets too thick to handle.  You may take a hit in efficiency if you drop it too far though.

Cheers,
Brad

Sounds like a lot of extra work, do you have more than one Mash Tun? I would go shop around for a new Mas Tun Large enough to do the job. I picked mine up at WallyWorld ($8.99 Because it was missing Parts) and transfer your manifold to it. Problem solved.

Guess I should have gotten the 10gal cooler in the first place.  Live and learn.

(So now if I have and extra 5 gal... what can I do with that?)
