Hi, found this because i have the same problem.. Does the yeast for off after a while? I went for the second fermentation option and added sugar but only after i opened a bottle ( probably 2 weeks after bottling) and it had no fizz, so i decided to add some carbonation sugar, but nothing's changed 2 weeks later no, so I'm wondering whether i just simply waited too long/ fermented too long? taste otherwise is to die for....
