So I have been doing all grain 3 gallon batches in my 5 gallon kettle recently. So my major problem I've been having is mash effeciency. I tthink my problem is that the bottom of my kettle, on my electric burner on the stove, runs about 7 to 10 degrees hotter than my top half of my water. So do I take the kettle off during my mash? And just set it back on the burner if I get below 150? I think I screwed up my saison I brewed last night. I found the water at the bottom was around 160, whIle my top water, which I was temping, was 152ish. So I just want an idea how to fix this before I brew again. Any advice is much appreciated.
