Well, the title says it all. I'm looking brew a small, experimental batch and I'm wondering if it's prudent to use this big 10-gallon igloo cooler mash tun. The grain bill is around 7 lbs so @ 1.5 qt/lb, that's about 2.5 gal of strike water. I was reading somewhere about the height/volume of the mash compared to the surface area of the perforated dome, can affect efficiency. Am I overthinking this or is there something to it?
