Mashing 2 1/2 gallon batch in a 10 gallon cooler
|
|
Title says it all. Is a 10 gallon cooler too big?

What part of too big are you concerned about?
If you are talking about heat loss...if you preheat your mash tun all the way up you will probably be fine...some people make a floating lid of styrofoam that they set on top of the grain bed if they are worried about it. It helps hold the heat in.

That's a good idea. With that much dead space, I wasn't sure if it would hold the temp..

Yup, what Revvy said. I tried a smaller sized batch in a 10 gallon and it lost heat like crazy. I would try the stryofoam route.

Can I really put the styrofoam right on top of the grain bed?

Why not? You're not worried about sanitation at this point. It's pre-boil.

I swear I once saw one covered in duct tape posted on here...

Come to think of it, it might not have been duct tape, but aluminum foil...I'm thinking the glue might not be a good idea in the mash... Just cut a piece of foam to size(less the the ID of the cooler), and get some ultra heavy duty aluminum foil and wrap several layers around it. You'll seal up the foam (which will prevent little crumbles getting in the tun) and the foil will also help hold in heat.

Grain bed depth??? I thought this when you posted this, no one touched on it. If you batch sparge, I dont know if it matters anyway... but grain bed depth is something to be considered generally.
