Most calcs/charts for residual CO2 only go up to 80° (including iBrewmaster) but I brewed a saison that I warmed to 91° in order to get it funky and prevent it from stalling. How do I calculate the residual CO2? I can't even find the formula to determine residual CO2.
I would like 2.2vols for 5gals, primed with dextrose. I can assume that it wouldn't make too much of a difference but I also don't want to over-carb because it might make it difficult to quaff. (9.5%ABV, 1.001FG beers should always be quaffable, lol)
Thanks for you help!
