About 15 years ago I bought an all grain setup (or so I was told). Life got complicated and I never did anything with it except let it keep dust off of the attic floor.
The parts I have include:
A 1/2 barrel keg with top cut off. I see them used as keggles here, but I think when I bought it I was supposed to use it as part of the sparging setup. Maybe I was supposed to boil in it too, but the place I lived it at the time had no place try to boil in a keg.
I have a copper tube with holes in it to sprinkle water on the grain as it spun around. The tube has a fitting on the top to let warm water in. I assume I was supposed to have the grain in some sort of giant colander or bag or something.
And I have a orange 5 gallon cylindrical cooler I was supposed to add a fitting to so I could connect a hose to the copper tube. The cooler has been used many times to dispense liquids, but never to sparge grain.
I also have some large enameled pots that look like the ones used to boil crabs. I think I bought these to boil in, but they are too thin and the wort burns to the bottom (I figured this out while doing a partial grain full boil).
Keeping in mind that I bought this stuff 15 years ago and I've spend a lot of those years killing brain cells, does this equipment list make sense for an all grain setup?
