Yeti Clone- Mash Tun size and Mash Temp

[jasonclick]

I'm planning on making a yeti clone scaled up to 10 gallons... i've never done a 10 gallon brew or brewed a stout.

Here's a link to the recipe:

I've got 2 questions:
since this will be roughly 40 pounds or grain, will it fit into my Sanke Keg mash tun?
If you look at the recipe, it says to mash @ 149 F for 90 minutes. Wouldn't that be a thinner beer? I would think I'd mash around 156 or so. I'm sure I'm missing something there

Thanks for the help!

Another good reason to not like clone recipes. It's hard to say what will work on their system vs yours. Rough math says you'll fit 40# of grain in a 15g MLT at a grist ratio of ~1.1 or so. Doable, but you might run into some problems. The 90 minute mash seems a bit long, but it might be needed pushing the system this far. I have a very, very vague recollection of the Yeti since I only tried it once in their tasting room about 4 years ago, but I seem to remember it being not all that thick/chewy of a beer. That may be why a lower temp combined with the author's process on the author's system might be giving them a 'clone'. It might not work at all on your system & there's definitely other roads that would get you to the final product. From my vague recollection of the Yeti & knowing how my old system worked, I would've started my trial runs at a regular mash thickness/time but at 153.

My first thought would to be taking out some of the 2 row & replacing with DME so you can do a mash more similar to what you're used to brewing. It might take a couple of attempts. If I were going to attempt this, I'd definitely be pulling out my tiny MLT I use for starters & doing 1 gallon test batches before committing to that much grain. No 2 systems are going to work the same, nor processes for that matter. Good luck.
