Okay so I have been reading tons lately on going full mash!! Got all the equipment I need to do this, well not all, but the bare basics. I go to the brew store yesterday and get all my grains for my " Downtown Leroy Brown Ale ", my name for it.... I ask the HBS some pick their brain questions since the owner is a master brewer. I am told to pour the grains in my cooler, heat the water to around 165-168, and only cover the grain bead about an inch to 2 inches.....hunh? Everything I have been reading says to fill the cooler with about 3-4 gallons of water......am I crazy, been reading the wrong material, or just plain gone nuts here and need to drink some more homebrew before reading another piece of advice..... Would love some help with this to get more clarity!!!!
