So how does it work? You start at the Hot Liquor Tank on the top, where you add hot water. As that heats, it flows downward towards a tank full of Mash Tun, then a kettle full of hops.
That tank boils the combination and adds flavor—a very hoppy flavor, in fact—next, a cooling coil and fermenter makes the brew chilly and drinkable.
You can literally watch as your beer is made in front of you and, after a week, you can drink up your success. Then, you'll always have a weird-looking Christmas tree in your house. Win-win.
