Guide

Before you start

Choose a style target if it helps, then adjust the CO₂ level to suit the beer, bottle strength, and how you like it served.

Method

How this is estimated

The estimate uses your beer volume, beer temperature, target carbonation, and sugar type. The style table is only a guide; the sugar amount comes from the CO₂ level you enter.

Safety and limits

A few notes

Do not bottle until fermentation is finished. Too much priming sugar can build dangerous pressure in the bottles.

Use accurate measurements for the best estimate.
