Wit and carbonation

So I brewed the honey hibiscus wit Kit from AHS and it has been in bottles for 3 Weeks now and barely had any carbonation. Are wits known to take a while to carb? Was leaving this brew in primary for 1.5 months (to reduce sulphur) to long? It has been sitting at + or - 70* the whole time.

 

How much priming sugar did you bottle with?

 

4 oz corn sugar

 

That seems like enough sugar and three weeks should be long enough. Do you have any sediment in the bottom of your bottles? The only thing I can think of is your yeast all settled out and when you bottled you didn't get enough into the bottles. You can put a little bit of yeast in each bottle but it sounds like a pain to do.

 

This is a pain, I did it once. Completely (emphasize that) flat beer after 4 maybe even 5 weeks. Uncapped all the bottles, re-hydrated some dried cooper's and calculated the amount of rehydrated yeast (in ml's) to add to each bottle. Using a syringe, added yeast to each bottle and re-capped. The good news is, they carbonated and rather quickly. I suppose there are worse things in life, but I really don't want to do this again. It was really disappointing, week after week, hoping the beer would carbonate and it just didn't. All's well that ends well right?
