I just did a search on my local craigslist and someone is selling a 20 gallon aluminum stock pot with lid for $60. I only make 5 gallon batches... will this this be way too big for my needs or should I go and buy it? Just a little background... I've only made 2 brews so far and both extracts. I'm trying to put together equipment for all grain but I only intend to make 5 gallons at a time.

I got a 15 gallon stainless with lid for under $100 off CL. I would hold out for stainless. 15 is great for 5 gallons, never boils over. 20 might get a little annoying because of size, but I wouldn't say it's too big. Plus it allows you to do a 10 gallon batch if you ever decide to split with a friend or something. Unless it's really wide, then your evaporation rate might be really high.

I use a 20 gal aluminum pot. I brew both 5 and 10 gal batches. I don't see any reason why filling a pot 25+% would be a problem.

That's also an incredible price assuming good condition.

Also I see no problem using aluminum vs. stainless steel for a brew kettle. If you take good care of it, it will easily outlive you.

I too am looking at a 80qt or 100qt aluminum for my starting out on 5 gal batches. I plan to put a weldless valve on it too. 10 gal is roughly 15" dia with a 20 gal at 19" and 25 gal at 20". The only thing I can think is that it has more surface area to the burner and may have more boil off?

I think for a 5 gallon batch in a pot like that you'd have to start with a boil volume of 7+ gallons. It wouldn't even fill the pot halfway! If I was only ever going to do 5 gallon batches, I'd start with a 40 quart pot.

If you do brew in a bag (BIAB) you will like having at least 12 and 15 is great for big beers. 20 is overkill in my opinion. BIAB cuts way down on equipment needs. Great thread on this forum.

I do 5gal brews using the BIAB method. I mash in a Bayou Classic 7 or 7.5 gal aluminum pot. Works great! Not too much head space so I keep good temps during the mash (with proper insulation) and the 5 gal paint strainer bag fits perfectly over the mouth of the pot and sits in the water enough to keep the grains off the bottom but well submerged using 4 gal to mash. (see pic below)

When I started I was doing 5 gallon batches, after moving up to BIAB (same setup as the picture above) I wanted to do 10 gallon batches so I set up a 3 tier gravity system, now I wish I had a bigger pot to do 15 gallon batches. If you like the hobby and think you will stay with it buy the biggest pot you can afford.

Agreed. I also have a 15 gal SS pot I use as well. The larger SS one has a larger diameter and works great for those full 7 gal boils. Then I just transfer back to the smaller aluminum pot after the boil to cool in an ice bath while using an immersion chiller.. The transfer helps promote cooling, too.
