Got about ten batches under my belt during the last year. Have decided kinda like this hobby and need to invest a bit more. My brew pot is ss and I bought it as a kit. Problems I have with it: no matter how much I stir I always seem to get scorch marks on bottom of pot. Also before pot gets to a boil it rocks back and forth. Actually believe this rocking action cracked the glass top of the stove. Please suggest quality pots that can easily handle five gal batches that shouldn't have the above issues
