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!
first, those calculators that try to "guestimate" residual co2 should be taken very lightly to begin with. At above, oh, 65 degrees or so, the amount of residual co2 is negligible and should just be ignored. A 2.2 volume saison seems like it would be undercarbed to me. I'd use no less than 5 ounces of corn sugar for 5 gallons of finished beer (or, 1 ounce per gallon). Saisons are usually very spritzy, to the point of being gushers sometimes, but a lower carb level is fine to not have gushers or bottle bombs!
