Not dumb at all, I did 1 teaspoon of sugar per 750mL bottle. Capped, gave a few shakes and then kept at ~18-20 degrees since. I have had 6 bottles so far, 1 was completely flat, 1 was almost at what I would call full fizz, the others only mild fizz (little hiss when you open, few bubbles as you drink).EvilTwin said:
