My last couple of bottle conditioned beers have come out a bit undercarbonated. Not flat. Not inconsistent*. Just less bubbly than I wanted/expected. I used 5 ounces of corn sugar for five gallons, which should have given me 2.5-2.6 volumes, but they seem closer to 2.0. So my question is whether there's anything that can change the default assumption of 0.86 volumes of CO2 at 68F after fermentation. I did cold crash these, but brought them back to ambient before bottling.
*Just to preempt the question that many of you will have: I use two different size bottles and I know which were filled first and last. I also use two small PET bottles for the first and last of the batch. So yes, I am sure that the priming sugar was adequately mixed.
