Can someone explain or better yet give me comparables for different Volumes of Co2? Honestly i'm not sure what i'm looking for. I usually shoot for the low end of volumes because i've gotten gushers from 2 batches were i used the full 5 oz corn sugar. Admittedly one of them was on 3 gallons but the other was on 5 gallons. Is there a big difference between 2.2 and 2.7? Assuming everything else is equal. Also i have used 3oz corn sugar in 3 separate batches/recipes and gotten 3 different outcomes This last batch is the Simcoe one. It's just a little bit flat. Used 3oz corn sugar on 5 gallons at 68deg F. Just afraid if i go the full 5oz like the calculator says i'll get gushers again. *man i really want to go to kegs so i don't have to deal with this, LOL.
