Carbonation Problems

I've bottle many batches but I can't seem to increase my carbonation. I've increased the amount of priming sugar from 4g to 5 to 6 and even close to 7 or 8. Alcohol is less than 5%, conditioning temps are fine, carbonation doesn't change much from one week to one month.

The thing that I might suspect be the problem however, is my siphoning technique. I rack to a secondary before bottling. Then I let it settle again and then bottle from there. My beer is crystal clear and there is maybe 1/4 of a centimetre of yeast at the bottom of each bottle.

Am I taking too much yeast out? What else could it be?

How long are you waiting and at what temp are the beers stored at?

The 3 weeks at 70 degrees, that we recommend is the minimum time it takes for average gravity beers to carbonate and condition. Higher grav beers take longer. Lower temperatures take longer.

And just because a beer is carbed @ three weeks, doesn't mean that it doesn't still taste like crap and won't need more time to condition.

Stouts and porters have taken me between 6 and 8 weeks to carb up..I have a 1.090 Belgian strong that took three months to carb up.

Temp and gravity are the two factors that contribute to the time it takes to carb beer. But if a beer's not ready yet, or seems low carbed, and you added the right amount of sugar to it, then it's not stalled, it's just not time yet.

Everything you need to know about carbing and conditioning, can be found here Of Patience and Bottle Conditioning. With emphasis on the word, "patience."

As long as I've been on here, this has been the issue 99% of the time, simply not waiting.

Yeah time can be a real pain, especially since it's colder now. Having my ambient close to 80 during the summer when I was at work led to beers being pretty nicely carbonated at 2 and 3 weeks. Even dropping to just 65-60 has made a month seem like not enough.

The time factor is probably it then. My ending gravities have been pretty high so that's probably why. Thanks Revvy!
