I'm going to make a variant of the Carbonated byrrgroni. In that recipe it calls for 1 charge to clear the gas, and 1 to carbonate with a yield of 2 drinks. If I want to do 8 drinks at once, (~600g total) how many more charges should I add? If I look at the other soda recipes, for that quantity of liquid, they recommend 1 clear, plus 2 charges, do you think the extra charge is necessary? Is that enough? Not clear to me how volume of liquid impacts # of charges necessary and I couldn't find an explanation in the class.
