To build my own good system it seems I'm only saving if I skimp on parts... a cheaper cooler, braided hose instead of a false bottom. I want it to be efficient and move up with me as I brew more and more.

What do people use for brewing 10-15 gallon batches?
Regarding the false bottom comment, IMHO they work the best in cylindrical MLTs or kettles. In my experience, the only cylindrical MLTs I've ever seen are 10gal. If you are wanting to do up to 15gal batches, you may want to reconsider the false bottom as I think the only way you can get 15gal of a beer with a 10gal MLT is to supplement with extract or just make a very low OG beer.

The attached pic is in my 12gal MLT. I did a 12gal batch of 1.070 wort. Very tight fit! I'll be upgrading to a 70qt rectangular cooler sometime this year.

EDIT: Grain bill had 30# of grain.

^ "very tight fit" is a bit of an understatement

Looks like Mount Malt Island rising in the middle...

Cheers!

First time poster. 3 yrs brewer here in MN.

6 yrs later and this thread is still giving. I used this model to a Tee (except my hose was 5ft). Cooler was $45+tax and parts were $32 w/tax. \

My only issue is that the spigot wants to spin. Any resolutions to that?

After doing more research we (my brother and I) decided we want to do 15g batches. For some of our grain bills this might reach 50#s! I guess the igloo is out of question. We need a big rectangular or something else. Any good suggestions?

I'm thinking of upgrading to this cooler for my bigger batches:

Read the comment "Xtreme Mash Tun". Has very good info on equipment to convert to a MLT.

If you want to do 15 gallon batches - 70 quart xtreme cooler
If you want to do 10 gallon batches - 70 or 52 quart xtreme cooler or 10 gallon rubbermaid/igloo cooler

Personally I'm going to go to the 52 quart xtreme for my 10 gallon batches, "IM HOPING" it holds heat even better than the 70 quart for 10 gallon, but not positive.

I have this cooler. I did end up with a slight amount of leaking at the bulkhead, so I silicone'd the opening and let it cure before re-assembling. I now get a tiny bit of leakage during the mash, but it's probably 2-4oz. of liquid, so I don't care. The silicone means it's not going into the insulation and getting nasty, so I've accepted it.

It's huge, though. I usually only have 20# of grain in it and it's maybe half full (I mash SUPER thin, too, usually 1.75-2qts/lb). I lose 10* overnight, which is how I mash. I don't usually lose even 1* in a 60m mash.

That's why I mention the 52 quart one for people as well if they want to do 10 gallons. It would fill it up more, and probably keep the heat better.

But if you notice, I don't lose even 1* in 60m...so that's about as good as you can get with a cooler that's not having heat applied. Losing 10* in an 8 hour mash seems reasonable and has worked for me, too. I have made adjustments to starting mash temps accordingly.
