I know that this is a pretty basic stuff, but I am trying to get equiptment together for gaoing AG. I am planning on going with the round beverage cooler type set up for masg and lauter, but I don't understandwhy the mash tun and lauter tun are two different vessels. Why can't I mash in to a cooler with a false bottom and steep the grains, then draw off of that and sparge all in the same cooler?

honestly, I don't see why someone would want a separate mash and lauter tun. you'd have to move the entire contents of the mash tun to the lauter tun in order to sparge...right?

I think only larger breweries have separate MT and LT, well, I am sure some homebrewers do too.

The reason you would separate them is so that you can start mashing while the first batch is sparging. There is no reason to do this if you are making standard 5gallon batches. But say you wanted to increase to 10 gallon, you could either build a bigger MLT or mash twice, combine and boil together.

I think the purpose of a dedicated mash tun is to be able to apply heat to raise the temp. The mash would need to be stirred during heating and a false bottom or manifold would interfere with this.

I'd wager that 90% of homebrewers who direct fire their mash have a combo mash/lauter. You don't really "stir" below the false bottom, you just recirculate the mash liquid with a pump. I don't know anyone that mashes in a cooler then dumps it into a dedicated lauter tun either.

Instead of the round picnic cooler, you might want to try something larger like the Igloo Ice Cube 50-68 qt coolers. Will allow you to do bigger beers or 10 gallon batches in the future.

This is good advice. My MLT is a 7-gallon cooler. Its more than big enough for standard 5 gallon batches, but not quite big enough for the bigger beers I'd like to do (like a dopplebock or Imperial IPA for SWMBO).

thanks for the info. that does make sense.

I kinda wish I'd gotten a 10gal cooler. but I was just gonna PM first...and after one PM batch I was sold on the whole 'grain' thing.

for now I'll stick to lighter beers and thicker mashes as needed til I upgrade my MLT.
