Cooler temp. & extra headspace

[NAZZ]

I have been fermenting a batch of beer thats has slowed or stopped on me. I used WLP 001 and have kept. it on the cool side between 65 & 68. I used a 2 liter starter and it started out at 1.060 and after 8 days has only dropped to 1.030. Is the cooler temps. just taking the yeast longer to attenuate? Also I am using a 15 gal. fermenter with 10 1/2 gals. of wort, will the extra headspace have anything to do with slow fermentation?
Thanks NAZZ

Yes, colder temperatures make the yeast work slower. Give it three weeks and I guarantee that you will have the attenuation that you seek.

No, extra headspace will not affect fermentation as far as I know.

Gently swirl your primary and move it to a warmer location.

Thanks, I just put some oak chips in. I will leave it for another two weeks and see where it is.
