D'Oh, Flat Stout
 

1 week Primary
3 weeks Secondary
2 weeks in the bottle

sneaked a peek and the first was AMAZING, rich Creamy head, incredibly smooth.

then I snuck another and it was totally flat.

after a few more samles I have yet to find one even close to that first one.

so now it just sits for another two weeks.

Is there any chance that you might have leaky capping?

This works better sooner after bottling, but you can put a balloon over the necks of some bottles and shake them and let them sit. If any of the balloons start inflating, you know that you have a problem.

good idea.

I'm pretty sure they're tight but I'll give it a shot

More time before you worry too much. Lots of times, my beer doesn't carb until week 3. Maybe you just got lucky with the first one. Check the caps, make sure they are on there well, but I wouldn't stress about this.

one of my first batches i forgot to mix the priming sugar in well well.
Some are carbonated nicely, others are not. I know its because i forgot to stir properly.

I mixed it very well.

it's a pretty heavy stout.
