The pot is cuttin it close for full boils if you ask me. I had a 30qt and could never fill it up enough and not boil over...I would always end up with at the most 5 gal going into primary after evaporation. I just upgraded to a 40 quart aluminum pot that should last me forever.
"So we were slammin' beers in the church parking lot..."
How you can fit 13 gallons in a 30quart pot I would like to know.
I also have a 60qt pot. The 30 qt worked for full boils but now it's a HLT. I had to fill it up to over the bead near the top and kill the heat a few times during the hot break while using a spray bottle.
Everything is better with a beer.
