I have access to a 60QT very heavy duty aluminum kettle. Now I know the aluminum is not a good insulator and will probably make sparging quite a frustrating ordeal but I would rather not spend 100$ on the pot I want just yet so I can start brewing sooner. Do you think it would be ok to use a really heavy duty aluminum pot or should I save my self some grief and just dump the dough on a heavy duty SS pot right now?
