BrewJacket
Universal lid that fits all Big Mouth Bubblers, drilled with a 1.75″ center hole for use with BrewJacket Immersion and a sleeved grommet for air release. We recommend adding two additional stoppers to the top of the rod to allow enough room for the sleeved grommet.
Rod sleeves are required for all low pH fermentations, including wine, cider, mead, sours, and kombucha.
Sanitizing with Star-San also requires rod sleeves.
