Oh, the Tippy-Dump. The Tippy-Dump sculpture is named after it's tipping Mash Tun. Place a garbage can on the built-in step and dump away after the brewing session is over. A nice benefit of the Tippy-Dump design is the placement of the Hot Liquor Tank under the Mash Tun. Excess heat rising above the Hot Liquor Tank helps keep the Mash Tun warm during the Mash. The 1550DD comes with 15 Gallon Kettles, but any of the three kettles can be later enlarged to the 26 gallon size (the 26 gallon Mash Tun basket and hardware must also be purchased). If you plan to mostly make 10 gallons at a time this is definitely the BrewSculpture for you. A folding handle allows you to pick up and move the system in a wheel barrow fashion. Easy to move, yet very stable in brewing position. Pros:Smaller footprint than the Flat Sculptures. Gravity from Mash Tun to Boil Kettle makes for an easy sparge. Built in casters for easy movement. Dump your mash after the brew is over. Built in Step for easy access to Mash Tun. Cons:Taller than the 1100 Flat System. You do have to use the step to mix grains into the Mash Tun.
