My last batch of beer was severely overcarb'ed and I don't want that to happen with the batch that I have lagering on my porch. When I look at Beersmith, which I used for this recipe, it says to use 4.32 oz of corn sugar. This sounds about right, but when I adjust the measured bottling volume I expect that amount to change with it but it doesn't, and this makes me suspicious. If I adjust the carb level it will change the sugar qty, as expected, but why doesn't bottling volume come into the picture?
There is also the carbonation tool, which takes carb level, temp, and batch size and that does work, but gives me a different answer than 4.32, more like 3.59.
Which of those answers would you use?
