The Fermonster Plastic Carboy fermenters are made from PET plastic (same as 2L soda bottles) which is far more resistant to oxygen than regular plastic. Plastic PET carboys are safer than glass carboy fermentors. Full carboys can be heavy and hard to maneuver and glass can break resulting in possible injury. Also with a wider 4" mouth, there is easy access for cleaning. Brilliantly clear with built-in 5-gallon and 6-gallon markers on the side for your convenience. One of our absolute favorite parts about it is the bottom center has an up cone and a little divvet in the center of that cone, which allows all the trub and yeast cake to settle on the bottom and is a perfect place for your racking cane to sit and siphon clean beer from. 7 Gallon Specifications: Lid with O-Ring and Hole for #10 Rubber Stopper Included Additional O-Rings and Lids (with and without hole) available Rubber Stopper and Airlock NOT included Weighs 3.1 lbs Rated to 140 degrees F Height: 20.9 inches Diameter: 11.3 inches Completely taste and odor free
