So I brewed an Irish stout that finished @ 1.013 after two weeks in fermentor. I moved it to the keg and plan on storing it that way for a while at 63 degrees. I did not add any sugar, just put enough C02 on it to seal. Anyone see any issues with this. Will carb on gas as St Patties day gets closer. Any way to figure what is should carb to while "resting"
