Determining Current CO2 Prior to Priming
« on: June 10, 2019, 06:55:45 PM »
I was reading in "Brew Like A Monk" that it's best to determine the existing level of dissolved CO2 before figuring out how much priming sugar to add before bottling. Anyone know how to do this? Is there a function on Beersmith that will compute it for you? (If my Beersmith was a VCR it would still be flashing 12:00 at me) Thanks in advance!

Beersmith like other software asks you for a temperature and then Beersmith figures out how much carbon dioxide is dissolved in the beer assuming that things are in equilibrium.  Assuming you use a bottling bucket and don't cold crash, the best temperature to use would be the current beer temperature.  Being a few degrees off doesn't make much of a difference.

Thanks very much for the quick reply! I didn't realize that Dr Smith was already doing the math.

You want to use the highest temp the beer reached.  That's because as the temp increases, dissolved CO2 comes put of solution.
