About This

NO MORE BOTTLE BOMBS (or BURPING): Carbo-Caps feature a built-in Pressure Relief Valve (PRV) to naturally carbonate beverages to perfection and release pressure the second it starts to get over carbonated.
⚠️COMPATIBILITY NOTICE - READ THIS!⚠️: These caps are precision-engineered for 38-1768 thread bottles only. All GT’s Synergy bottles (16oz or 48oz) are a PERFECT FIT. Also works with any 1/2-gallon or 1-gallon growler that uses a 38-1768 closure. Does NOT fit all 38mm bottles. Check before you wreck!
DURABLE AND REUSABLE: Crafted from high-quality materials, Carbo-Caps are built to last, providing sustainable carbonation solutions.
EFFORTLESS OPERATION: No need for external CO2 setups, just seal your brew with Carbo-Caps and let the natural carbonation do the work.
PRECISION CONTROL: The PRV ensures consistent carbonation levels for the perfect fizz in every bottle.
QUALITY GUARANTEED: Carbo-Caps are backed by our commitment to your satisfaction, enhancing your homebrewing experience with reliable carbonation.
