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.

Default I thought I was better at math

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.

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!
