I just received a Grainfather G40 for Christmas. I wanted to try and streamline my gravity based brewing set up, and I am getting tired of lifting heavy kettles, mash tuns, fermenters, etc. More importantly, I was fearing an eventual back injury from lifting on brew days. To work for my garage set up, I needed a way to easily move the Grainfather around so I could mash/boil/chill in the driveway and then roll it into the garage to pump the wort into my conical fermenters. I thought about a number of options and then remembered that they sell 55 gallon drum carts. Voila, instant Grainfather cart!
