HERMS systems put the runnings through quite a bit of temperature differential as it passes through the tubing and heat exchanger and back into the mash. It seems that gently introducing steam would be less detrimental. Of course, I'm relying on others' experience until I get my system built...
so how long would one stir the mash for? i read stirring is only good to do as u pour your grains in. So what do u do when youre ready to drain in the bk? wouldnt u want the grain to settle? or will there be a better false bottom than the ones widely used but still getting grain clogs? j/w b?c ive been trying to figure out a steam system but seems more difficult to brew with. i wanted to do stram b/c alot of big breweries use stram so it has to be the way to go.
