I bottled and capped my second batch of beer in 12 oz glass bottles and realized afterward I'd added far too little priming sugar. Recipe called for 3/4 teaspoon per bottle, and I only used heaping 1/8 teaspoons.

Is this batch a lost cause, or can it be salvaged?

How long ago did you bottle? – Graham Nov 8 '12 at 12:56
+1 to Graham's comment. If it were me, I'd chill a bottle after 3 weeks and see how the carbonation is before going to the effort of cracking 50 bottles and re-priming them. – JoeFish Nov 9 '12 at 17:11
Also, since you're new: when I say "chill", I mean put a bottle in the fridge overnight, then open it and pour into a glass to evaluate the carbonation. If you don't give it a long chill, the CO2 will not properly dissolve into the beer and the beer may seem flatter than it actually is. – JoeFish Nov 9 '12 at 17:12

Well, since you know how much sugar you added at first, you can add enough to cover the rest. I'd just take them out, uncap, add 5/8 teaspoons of sugar, recap, and let carb up again. You might even be alright to add the full 3/4 teaspoons since you will lose a little co2 from opening the bottles up. I don't know if adding the sugar will cause it to foam at all, either. It's better to give it a try and hope for the best than to dump it and never know.
