So I am talking with one of my padawans about the upcoming brew day tomorrow. They were reading an article, specifically about mead, that states: “allow 9-12 months to insure you will not have bottle bombs from carbonation”. My response was: “or you can take gravity readings and know way sooner.”
But that got me to thinking about carbonation and bottle bombs.
While I have had batches that were gushers I have never had a bottle bomb (knock on wood). But just exactly how over-carbonated does a beer have to be before a bomb potentially occurs? Now obviously it is better to let fermentation go to completion and then add priming solution to achieve proper carbing volume, but I just found this to be a curious pondering.
For example: If I were to anticipate a batch of anything to end in a FG of 1.014. At what gravity could I safely bottle it without having gushers or bombs? 1.016? 1.020? I guess the question is how many points of gravity = 1 volume of carb? How many volumes of carb can a standard bottle withstand?
Not looking to do any kind of independent scientific testing but just something I guess I never thought about before (especially since I keg everything nowadays).
