Well, it's now bottled. The bottle time tasting had no buttery/butterscotch flavors so I think I'm in the clear as far as that.
I managed to screw something else up though, while heating the priming solution it boiled over in the microwave losing I'm guessing about half. I was thinking about adding some corn sugar to make up for the loss, but decided to just rune with it and risk under carbonating. I can always go back and reprime the bottles if it's too bad.
I'm trying a set of flip tops that I recently bought. I'm hoping they hold a seal better than the 1 L fliptops I've got.
