Advice request for a larger-than-normal mash tun
« on: March 17, 2020, 07:27:03 PM »
I'm going to switch to all-grain brewing (yay!) and normally make 6 gallon batches. I've read a lot about the considerations for optimal mash tuns for my usage, but I'm wondering if some of you experienced folks wouldn't mind chiming in on my following idea for a larger-than-normal mash tun?

I normally ferment 6-gal batches with OGs of 1.050-1.065. I think an 8-10 gal mash tun would be fine. (Round or not, it doesn't matter to me, as I'll be using a custom manifold and not a false bottom.)  Sometimes, I do back-to-back batches (i.e. a pair of 6-gal fermenters) so a larger mash tun would be nice to have.
Idea: What about the following 70 quart Coleman cooler?
https://www.amazon.com/Coleman-Quart-Xtreme-Marine-Cooler/dp/B00DP67PZY/ref=pd_sbs_468_18
This cooler is taller, not longer, so I'm thinking for 6-gal batches, I'd only fill it halfway and still have a decent grain bed. For double batches, a deeper grain bed seems fine based on what I've read.

Does this sound feasible? Or do y'all think I might be pushing my luck? :)

Thx in advance!

70 quart should be fine. I used a 100 quart coleman cooler for my 5 to 6 gallon batches. I used whatever water volumes were needed for the size of the grain bill not the size of the cooler.
