Beer not fermenting...

[Gderem]

Just tried one of these beers. Bottled it 3 weeks ago. Doesn't taste carbonated. I did a heaping 1/2 cup of corn sugar, making it a bit over 1/2 cup. Do you think I used too little?

There are bubbles and a tiny bit of foam, but doesn't taste like it. How much longer do you suspect I need to put this batch away for before trying again?

Taste is ok, time and carbonation should make this batch good.

I do think you could have used too little priming sugar (for a 5 gallon batch anyway) - once I started weighing my corn sugar I discovered that 5 oz will almost fill a cup. It also just may need another week or two to finish carbonating, some batches just take longer than others. One thing you might try is rolling the bottles back and forth a few times to swirl up the yeast, then give them another week or two to get as much as you can out of them.
