This is the second batch I've bottled with absolutely no carbonation. I'm so frustrated being new with this and both of my sets of beer have no had any bubbles. I've used the correct sugar and I followed all instructions for mixture of sugar and wort prior to bottling. What could I be doing wrong? I had excellent yeast growth this time around. Am I suppose to be loosing the yeast at the bottom for bottling o what? Plz help me as I'm getting consistently upset with my terrible brewing abilities
