This is how big your Mash Tun needs to be - Page 3

I was going to include all kinds of variables but then the table would have been quite large. I picked 1.25qt/lb because it's pretty common.

Also need to consider the dead space in the lid of the cooler.

Cooler manufacturers use that space for volume but we cant.

Mash calculator on the Green Bay Rackers calcs page scroll down to "Can I Mash It?"

Thanks Bobby. One day i need to drop down to Piscataway to watch you in action. I'm itching to go AG

Howdy! I'm trying to pick a cooler out for a new system I'm trying to build up. I'm looking to make 5 gallon batches at barley wine strength without sparging. I'm looking at about 54% efficiency, correct me if I'm wrong. How do I plug this in.

I hope someone's still watching this thread. great sticky!

That's where I just grab my BTP software and mock it up. Assuming you mean a STRONG barleywine like 1.100, at 55% efficiency it would take about 25lbs of grain with 10 gallons of water (that's a 1.6qt/lb ratio) to drain off about 7.25g of wort. The total volume in the MLT would be 13.5gallons. A 52qt cooler would be borderline but doable.

Thats what I was thinking lol.

Nice chart though. I am going to start all grain soon so this chart is going to come in handy. Thanks bobby!!

So I just finished building a five gallon mash tun from a round rubbermaid cooler (before reading this thread). I'm a noob at AG so bear with me. My question deals with sparging. If I'm maxed out at 12 lbs as the chart says, can I do a batch sparge or do I have to fly sparge? Does one's sparging method make any difference relating to the max grain/OG the tun can handle?
I ask because I plan on doing EdWort's Haus IPA this weekend and I need to know if I should build a sparge arm. I'm assuming batch sparging shouldn't be much different. I would just have to do more batch sparges to get to my target volume?
Thanks for the help.

Only if you sparge or not. Sparge technique doesn't matter. (Though I suppose, if you fly, you want room to have an inch of water above the grain.)

sorry if this is my own stupidity, but i do not see the chart anywhere on the posts. I assume that it was an image in Bobby M's original post. Do I have to be a premium supporter to see images? I didn't think so. Maybe its the computer I am on. Any help? Maybe re-paste it in a new post or let me know if I can find the chart posted somewhere else. Thanks!
