any thoughts on having a rectangle-shaped igloo cooler mash tun vs. the tall circular (gatorade containers?) cooler mash tuns re: stuck/very sticky mashes?
My experience is that because the grain bed is so much deeper in round ones, they're more prone to sticking.
I would have to agree. However, I found that if the flow from my Igloo (tall round) begins to slow, I simply open the ball valve a little more and the flow increases. On very rare occasion did this solution fail. But for the most part, my igloo works great.
