Help... It just wont carbonate

[mackenziemicro]

OK so it is carbonating just no where near as much as I expect..... I have brewed 3 PM batches after doing a few kit and extract batches. The first PM batch carbed well after 10 days or so. First batch was 100g of corn sugar dissolved in boiling water added in the bottling bucket in the standard way.... The second PM batch I used 130 g for about 18 litres and after 5 weeks its still under carbed at a barmy 26°c room temp all I get is a tiny little puff on opening the bottle and very little fizz or head..... third batch I used 150g corn sugar and after 14 days again a tiny pfff on opening and very little carbonation.

For all batches Primary was 7 days and secondary 7-10 days all batches have a good clarity - fermentation temp is between 19-22 degrees all batches used same yeast Dunstar Nottingham rehydrated as per instructions.

Any ideas on what I can change, I was really nervous putting the 150g in the last batch was expecting foamers or bottle bombs not a pathetif pfff......

A fully conditioned beer will have the CO2 forced into solution if the bottle is chilled for a few days before opening. A bottle with fully conditioned beer will release less CO2 on opening than one that has not been chilled. The bottle that is not chilled will have more free CO2 in the head space.

Another possible problem is the priming sugar was not mixed through out the beer at bottling time. Some bottles will have more carbonation than other bottles. (I number the first 10 bottles and the last 10 bottles in case I run into an unequal carbonation problem.)
Have you poured multiple bottles from each batch?

Leaking gaskets on swing tops?

Second and third batches very high OG beers which will take much longer to bottle condition?

Soap residue in your glasses which immediately kills head formation?

I had a similar problem - turns out my wing capper was cracking the bottles. Any hairlines in the top of the neck?
