I am trying to learn a little bit more about carbonation levels for bottle conditioned beer. I tried reading up on the subject, but have a few questions:
1. Assuming gallons are the form of measurement, when a beer has 2.5 volumes of Co2, does this mean for every gallon of beer, 2.5 gallons of Co2 are dissolved in the liquid?
2. From my understanding, Co2 more easily dissolves into liquids at lower temperatures. How does this affect the amount of carbonation in the beer? For instance, if you bottle and condition at 66F and then later keep in the fridge at 35F, is the amount of Co2 in the liquid the same? Likewise, what would happen if the beer is stored at higher temperature? I'm just confused because the online priming calculators use bottling temp, but don't use storage/fridge temp so I am unsure how temps affect these numbers.
3. What is the max PSI a normal, 12 oz. glass beer bottle can hold?
4. Obviously the carbonation levels in the bottle will not change based on temperature since the yeast produce X amount of Co2. What determines how much Co2 is in the liquid and how much is in the headspace?
Thanks for the help!
