Porter doesn't fully carb

[skwaler]

Hi all,

My first batch of porter didn't fully carb up despite using the same ratio of sugar I've used many times for my other ales. I tried turning the bottles every few days etc...

In the end I had to open them back up and add a little more (1/4 tsp) sugar. After a week or so they were carbonated well (some a little too well). I assumed I had made an error adding the sugar to the bottling bucket.

My second batch of porter has been in the bottle for 4 weeks, and I have the same issue...under carbonated beer.

Is there anything special about a porter that could be causing this?

Grain bill was: Pale, Crystal, brown & chocolate.
Yeast: S-04

Thanks

SK.

are you keeping the bottles warm? if they are outside, or in a cold part of the house, carbonation will take longer.

Temp is 20-22C

My other beers carb up nicely in under a week.

I've brewed about 20-30 beers and the bottles have carbed up every time. Except the very last batch I've made, it's been about 3 - 4 weeks and still not much carbonation at all. This is the first time I've used WLP051 Cal V ale yeast and from what I read it can be very temperamental. I can only assume it's gone to sleep when it gets cold at night, however it doesn't really get *too* cold indoors hre in Sydney in winter. I'm just going to leve it for a month or so or drink it all flat
