Priming Calculator

Calculates how much priming sugar you need for bottling homebrew beer. The calculator suggests the desired amount of corn sugar (dextrose), so you can score a perfectly carbonated beer every time.







Amount of priming sugar needed (in ounces):

The calculator takes all important factors into consideration such as the amount of Co2 that got dissolved during fermentation. Based on the temperature of the beer, it’s possible to determine how much Co2 is still present and take it into consideration when providing you with the correct amount of priming sugar.

For general advice on popular styles, you can refer to the table below.

Lager/Pilsner2.5-2.8
IPA/APA2.2-2.7
Amber2.20-2.7
Stout/Porter1.8-2.5
British Brown Ales1.6-2.2
Lambic2.8-4.0
Wheat2.6-4.0
Recommended Co2 levels in beer styles

This table serves only as a pointer and hasn’t covered all styles in detail. Although there are certain rules like the minimal amount of Co2 for beer styles, it’s possible to adjust it to your preference and what you want to achieve.

Personally, I like sparkier beers, so for instance, I always carbonate my stouts and porters to 2.5 because even 2.0 is too weak for my taste. Don’t over-carbonate or under-carbonate, find your ideal range by experimenting, guessing, or following recipe guides.
