Have you run the numbers to make sure 100 gallons of combined mash tun capacity will be large enough for you? That would support a mash of about 250 lbs. of grain with a mash thickness of 1.25 qt/lb. If you're making an 80 gallon batch (post boil volume into the fermenter), that would let you brew a 1.090 beer at ~80% efficiency...maybe too ambitious for a big beer? You can always brew back to back to go bigger.

I'm assuming that many of the formulas I use for smaller batches will scale up to larger ones. Not really sure about that though.

Not that ANYBODY really cares about this or even thinks about abiding by it, but isn't against the law to exceed the 100 gallon Per Adult Per Year limit set by the feds?

I think it is a cool idea, I see so major issues with the power needed to heat and maintain the strike temp, not to mention heating and maintaining the boil...


But what the hell......

The stock tank is perfect but I believe Cold Steel is a bit freaked that it doesn't have some giant FDA approval on it

They make aluminum stock tanks. but I doubt the FDA put their "Food Safe" lable on those either.

*Edit*
see my later post about Galvanized Steel Stock Tanks

hehehe I am freaked. I love beer. I hate cancer. Dont get me wrong. This thing is money!!! Plus its so freakin cheap. I can get one brand new for $69 bucks! The inner cheapo is trying to justify, believe me. My intension is not to offend if have I am sorry.

I called again because i didnt know the plastic. It is HDPE. I asked her if she considered it to be a food grade plastic and she said no.
She said it has a working temp. of -20 to 140 degrees. I asked her what happens after those temps and she said its untested.
High-density polyethylene - Wikipedia, the free encyclopedia

"A food-grade container is one that will not transfer non-food chemicals
into the food and contains no chemicals which would be hazardous to human
health."

All I am doing is stating facts. (Except for the cancer part, I have no idea. It just seems like everything causes cancer)


Aluminum stock tanks, I cant find them online. I found fuel tanks but nothing that would work.

I still think the best idea is 2 mash tuns, for me.

It is against the law to exceed the 100 gallon Of Fermented Beer Per Adult Per Year limit.

It is not against the law to make enormous quantities of unfermented wort in any time period.

If my brew club gets together and cooks up an 85 gallon batch of unfermented wort and I take home 5 gallons and put the yeast in at home I consider it to be 5 gallons of my personal limit, not 85 gallons towards the limit of the guys driveway we did the boil in.

I couldn't find Aluminum either, but I did find a couple of articles about Galvanized steel being food safe as long as the plating is intact. I just read several articles regarding cooking in Galvanized Steel trash cans (As an oven, as a Smoker, and as a steamer.)

Galvinized steel is still used in drinking water pipes today, and is a cheap alternative, similarly priced to the HDPE stock tank.

Also check out http://www.plastic-mart.com/class.php?cat=9
Most of their tanks are FdA approved, but are more than $80/100gal

http://www.plastic-mart.com/class.php?item=49 looks like a winner for you!

Another option is to purchase a tank of sufficient size from a tank supply (USplastics) . Possibly a cone bottom?

edit... oops, forgot about the FDA until 140degF.
