Sorry..i've read a dozen or so threads on this but have not found what i'm looking for.
Anyway, i brewed my first batch (american pale extract kit) about 2 months back..fermentor for 2.5-3 weeks, bottled (boiled the priming sugar and let cool and added but did not stir) and let sit at room temp (~70-75) for 3 weeks. After that i took our first 6 pack camping and it was AWESOME..nice carbonation..maybe even a little high.
However, since then 10 or so are almost without carbonation. I've tried rolling the bottles to rouse the yeast last week and let sit for a week and still mostly flat??
It seems unlikely that the first 6 could be so good, and the next 10-12 flat. I don't think I have any leaks..is there anyway to check this? Any other suggestions on my technique?
