These sugar drops carbonate your bottled beer by giving the yeast a little more sugar to eat. Inside a sealed beer bottle, the CO2 has no way to escape, thereby dissolving into the beer and creating carbonation! The recommended dosage is 3-5 tablets for a 12 fl. oz. bottle. Condition for 2 weeks at room temperature. High carbonation: 5 tablets. Normal carbonation: 4 tablets. Low carbonation 3 tablets. Each pack contains approximately 270 tablets. Made from pure dextrose.
