I would like to understand how to calculate how much priming wort I need to add at the bottling stage to reach a desired carbonation.
Desired Carbonation: 6 g/l Extract: 17°P Amount of fermented beer: 17 l
- I will fill at 22°C so I have 1.6 g/l.
- I require 6 g/l so I need to add 4.4 g/l carbon dioxide.
- Sugar(extract) is split 50% alcohol and 50% carbon dioxide so I need to add 8.8 g/l of extract.
- My wart is 17°P which is 170 g/l so…
Working backwards with a guess I can see that I need to add approximately 0.9L but I would like to know how to perform the final calculation to get the precise amount.
