🍺 Top-down Brew: Carbonation With Sugar From Liquid Weights

Purpose: Determine the amount of sugar needed to achieve a desired level of natural carbonation. The volume is determined from weight and specific gravity.




Beer temperature (F or C)
Target carbonation (volumes CO2)

Notes

This calculator differs from most priming sugar calculators by using liquid weights to determine the beer volume. This approach is useful for bottling buckets or kegs that have no volume markings. The weight approach was inspired by an example from Lewis (2021 July-August, BYO Magazine, p. 38).

Basic carbonation reference (volumes of CO2):
