So was in the process of making my MLT according to these directions. great idea btw. But after reading about all of the leak problems, and hard times finding 10 gal round coolers or SS washers, i got an idea.

Instead of trying to make a new seal and risk a leak, i tried to use the original. It was a perfect fit with the ball valve! Would of never guessed. So wrapped the spigot with teflon tape, and tested it. absolutely no leaks. For the braid i just wedged it in the inside of the original seal, and it too fit almost perfectly.



AG here i come!

Thanks for the tip! He does indeed have some more, so I'll be getting one of those false bottoms for sure. I have a couple of questions for you also:

1. What did you use for a pickup tube? Any pics?
2. Since his false bottoms aren't domed, did you have to add any spacers to raise it off the bottom? If so, what did you use?

Thanks again!

The ones that Jay makes aren't domed, I would just use some S/S bolts and nuts to make some legs for it to hold the false bottom up about an inch or two off the bottom of the cooler. The setup im using right now is the 10gal A/G cooler setup from morebeer.com. I got it about a year ago before I even knew about this site and looking back I wish I did. I'm in the process of piecing together a brutus ten and I'm going to use the false bottom that I got from Jaybird. I'd definetley get one before he runs out. As for the pickup tube on a flat false bottom, look back through the thread and you'll see a couple different setups that use rigid pipe, copper or S/S would both work fine.

*Edit* The thread I was referring too is the one in the classified section where he is selling the false bottoms.

Ok,
so a quick question here for all of you who have built and used one of these rubbermaid cooler MLT's...

I just got my 10 gallon cooler, and have not had a chance to use it yet, and I am trying to wrap my head around batch sizes.

Assuming that I am doing a "normal" 4% - 5% alcohol beer, what is the largest batch size that a 10 gallon MLT will accommodate? I know that I should be able to run a few calculations and figure this out, but for some reason my head is just not wrapping around the concept well, and I figure, you all have used the things, I will just ask what batch sizes you are making.

I used a 5 gallon cooler before this and I was able to get up to a 1.055 starting gravity with this much volume for a 5.5 gallon batch. This works out to about 5-6% ABV depending on terminal gravity readings (my Pale Ales came out at 5.6%). Now, my efficiency was only 70%, so if you could get better efficiency then you would be able to brew a "bigger" beer. So if I take this same formula and apply it to my new 10 gallon setup, then I should be able to make a 10 gallon batch of beer with the same ABV. I wouldn't count on doing much more than 10 gallons, although if you were able to get great efficiency and aim for a 4-4.5% ABV you might be able to get a 15 gallon batch out of one mash.

Thanks, that is the kind of info I am looking for. I usually do beers in the 4% - 5% range, and I am in the process of converting a couple of kegs to go with my new rubbermaid cooler, so based upon what you said, I should have no problem at all doing 10 - 12 gallon batches once all my new gear is ready to go.

I've been on the prowl for a keg myself...so I can make a keggle and do 10 gallon batches. With my 5 gallon batches, I normally collect 7-7.5 gallons but my last runnings are typically 1.03x or so. I think there are still some sugars in there, which means I could probably do another round of sparging and extract a bit more wort for the boil. I wonder myself if I could possibly get enough wort to do a 15 gallon batch. Or how about this: Take the first 7.5 gallons and make an IPA out of that, then take the next 7.5 gallons and make a blonde, or pale ale? Damn, now I'm getting all excited about brewing and I still have 7 hours of work left .

What would you ferment a 10 gallon batch in? Could you split it into 2 5 gallon carbouys?

That's what I was thinking. I actually have a 6.5 gallon and two 6 gallons. Or if you have some buckets for primaries, that would work fine too.

As to myself, I am shooting for about 12 gallon batches, the keggle being able to hold a max of 15.5 gallons. With some foam control, I would thing that 12 gallons should be no problem. As to fermenting a batch that size, I currently have about a dozen carboys, pretty much evenly split between 5 gallon and 6-6.5 gallon. My thought is to split a 12 gallon batch between three of them. Not only will this greatly increase my capacity, versus my current 5 gallon batches, but it will also give me the ability to do a lot of experimenting. Different yeasts on the same recipe, same yeast but at different temperatures, that type of thing. Now I just have to finish building all the toys so that I can get started.
