We believe this conversation is important, ongoing, dynamic, and bridges the gaps of age, gender, politics, etc. We bring homebrew to the masses (classes, demonstrations, competitions, beer festivals, and advertising outside hobby publications), Northern Brewer has been in the thick of it since 1993. THE PERFECT GLASS CARBOY FOR CRAFT BEER ENTHUSIASTS The fermentor that started it all, reinvented again! We’ve taken the revolutionary Big Mouth Bubbler glass and re-engineered it with the help of world-class Polish master glassmakers. Ribbed silicone rings ensure a positive seal while the non-threaded design allows the lid to move preventing an out-of-control fermentation from dangerously pressurizing your fermentor. WATCH. LEARN. ENJOY. Our Brewmasters are very passionate about brewing and want you to have an amazing brewing experience. Watch our detailed step by step brewmaster videos so you too can brew your best. Someday we want homebrewing to be as common a household craft in America as vegetable gardening, and we know that our hobby/craft/shared passion/obsession won’t get there through complacency.
