Bottle Tower for a complete sanitizing and bottle draining package. With this bottle tower you will be able to stack up to 9 easily assembled and unassembled inserts plus the new Monster Cleaner as your top insert (Monster Cleaner sold separately). The top insert facilitates easy drying of our PET Carboy or FerMonster for a complete draining station! For heavy brewers, draining is made easy as our base is designed to empty directly into a sink with a standard 3/8" hose.
