I have mash tun questions. I've read a few threads, where people have talked about them. But not in detail. What exactly is a mash tun?. Why a igloo "water" cooler?, what seperates the grains from wort? Why a mash tun? My pipeline is far from purchasaing one. Due to, not quit the pipeline I want & finances. But, just curious. info for the future, I guess.
