Wouldn't this method be ok to do an all grain brew? I don't see what the difference would be by using a cooler with slotted or drilled pipe, except it might be easier to control temps with a cooler...is that all? Am I missing something?
Oop! Yes! What he said! Sorry, I wasn't paying due attention to the AG aspect of the OPJust be aware that that thread is partial mashing. it's a mix between All Grain and extract. You could do the whole recipe that way but would need a larger pot for larger grain bill. A complete AG grain will be between ~10-15lbs of grain.
Nope, you're missing very little.
