Brewed up a batch of Kolsch a few weeks ago, got it in the bottles, while cleaning up discovered the priming sugar never made it in the bottling bucket. What the *ell is wrong with me, anyways uncapped them all and added a teaspoon of the priming sugar. So 2 weeks later when trying them out they seem flat. Do I uncap the rest and add more. or leave it alone. they are flat not kind of flat
