i did SOOO much research on this subject before going AG... i ended up going aluminum originally... NOW, i have stainless steel, just cause it's cooler :)

however, there seemed to be equal pros and cons for each, and for the price you just can't beat aluminum... and if you're drilling through it to put valves and things, HOLLLLLY aluminum is easiser to work with than stainless... for me i've brewed with both... and i can't say i like one more than the other! so specially if you're just starting in AG - aluminum will help lower your initial cost..

Noob hear, but Aluminum has a lower BP than SS. So do Aluminum pots allow for quicker boiling of water/wort?

The property of consideration between aluminum and SS efficiencies is thermal conductivity. Aluminum is 215k at 115 deg C, whereas SS is 17k at the same temp. To reference, a very conductive metal, copper, is 400k, whereas an insulator, glass, is 1k.

This means that the heat transfer is more efficient in an aluminum pot. The effect may not be significant, as there are greater convective heat loss issues that overpower conductivity efficiencies. The surface area contact of the pot vs, the volume of the liquid being heated also levels the efficiency playing field much.

Here is the ref for the stated info:

Note that one key difference is that you can't use oxygen-based cleaners (like PBW and Oxyclean) to soak aluminum vessels. It will pit the metal. You have to wash and rinse immediately. With stainless, you can let it soak.

What is your budget for the pot

I just got a 19 gallon pot Stainless Steel for 170 from ontariobeerkegs.com

OBK has really great deals on pots... a few years back when I bought mine, discount ones were still 300$ and barely available in Canada - in those days aluminum was a significant cost savings, as you could get a big 20 gallon aluminum pot from bass pro shop for 130$ - now days I don't think it's worth it with OBK's price on kettles

I had to smuggle all my pots from the US 10 years ago. No one sold SS pots and when I found one that did, the price was just stupid. We have come a long way, but what took us so long?
