Default is my Mash tun large enough

I want to brew a batch with 18.5 # of grain in a 10 gallon round cooler.....I usually mash at 1.5 qts per pound....

This would call for 7 ish gallons of water, how can I tell if it will fit in my mash tun......

Volume wise, how many gallons it 18.5#'s of grain....

go here: Green Bay Rackers--Mash Calculators

Great site for easy quick mash calculations

According to the site it will take up 8.42 gallons so you should be good to go.

I have a 10 gallon round cooler with slotted copper manifold and my record is a double batch of the Bee Cave IPA. It was 25.5 lbs of grain and the mash fit with about 1/2" to spare at the top. However, I batch sparge and it was impossible to add enough sparge water to collect the required pre-boil runnings at one time. So, I had to sparge more than once. I think this is an advantage of fly sparging.

18.5 lbs of grain is no problem at all for your setup. Use the calculator mentioned in the post above, it's very helpful. Also, if your mashtun has a false bottom, be sure to subtract that volume out if you think it's going to be close.

I have been told that this doesn't factor for the lid though, and have been meaning to attend one of their meetings to mention this.
