Test, transfer and taste your fermenting beer like never before! The ported lid for Big Mouth Bubbler® Plastic is designed for maximum interaction with minimal oxygen exposure. Its port size fits standard brewing tools so you can monitor fermentation without unscrewing the lid. Your siphon, thief, small universal bung, and blowoff hose will all fit within the diameter of the lid port.
*Please note: these rings are only compatible with the Big Mouth Bubbler® Plastic, they will not fit the Big Mouth Bubbler® EVO 2. They are also incompatible with the Big Mouth Bubbler® Universal Lid.
Best of all, cleaning is easier with a modular lid. The white disc is separate from the blue screw ring, so you can disassemble for a deeper clean. And the screw ring works seamlessly with both single- and dual-port lids.
