If you keep your carboy in a fermentation locker or other area with little to no head space, every inch counts. We love these low-profile 2-piece airlocks for their compact size and simple design. Instead of a floating plastic "hat", the center piece is molded into the lid. One less thing to clean and misplace! This is the larger of the two mini airlocks we sell, holds more liquid than the smallest design, and is good for fermentations volumes up to 13 gallons.  Holds approximately 0.67 fl oz (20 ml) Chamber - 1-5/8" tall x 1-3/4" diameter Stem - 1-1/4" long Stopper not included

Use this specially made carboy bag to protect yourself and your beer! Carboys can be slippery, especially when wet. Our strong canvas bag allows you to more safely carry a carboy. If it is accidentally dropped the canvas will help contain the broken glass and reduce personal injury. Your beer also benefits as it is protected from light. UV Light interacts with compounds in hops to create skunky off flavor (editor note... I may not be a smart man but I do know skunky flavors in beer aren't good). These are made in the USA from heavy black canvas with strong nylon webbing that is stitched (very strong) to support the carboy when lifting. In the summer, you can help reduce high fermentation temps by placing frozen ice packs in between the canvas and the carboy.
