Notes

The beginner method of using 3/4 cup of corn sugar for carbonating a five gallon batch is simple but it has some serious drawbacks. The present calculator offers a more precise method to acheive the desired level of carbonation.

Basic carbonation reference (volumes of CO2):

Using over 3.0 volumes of CO2 is unsafe for standard beer bottles. Highly carbonated beers need sturdy Belgian ale bottles that have corks held in place with a wire basket.

If multiple temperatures were maintained during fermentation, the highest temperature is the one that should be used for the calculation.

A tip is to stir the beer gently in the bottling bucket with a sanitized spoon before filling the bottles to evenly mix the priming sugar solution. Uneven mixing can produce inconsistent levels of carbonation for the batch.
