This is possibly a stupid question but can shooting in cold weather affect the sensor where noticeable grain is introduced in the shot, more than normal?

How cold we talking? The only info I've heard on effects of cold have been positive, and that is when you're shooting really long exposures, because it keeps the sensor cooler.

Right around the freezing mark, -5C to 0C

I really can't imagine that it would at such a modestly cold temperature. I've certainly never had an issue and have used mine much lower than that, as have others.
The only effects I've heard of are positive ones related to long exposure. I poked around a bit online to see if I could find anything, and all I found was what I had already said.
Do you have specific images that show a manifestation of that? Are there other possible factors that could have caused it instead?

Perhaps condensation on the sensor or lens if you're taking it from a warm room directly into a cold environment.

On (very) long exposures you can have frost on you lens.
This happened for this shot : //concours.tikka2.com/gagnant.php?id=5
But it didn't seem to bother much the photographer : he was just afraid that frost could be visible on the photo.

Edit : from the photog : few hours at -15°C

Maybe its just me, I did a shoot in the mountains a couple weeks ago and just got around to editing the photos and have noticed an unusually high amount of grain in the images which were all shot at ISO100.

Underexposed any? look at the histogram of one of the originals. Snow will usually cause underexposure and bringing it back will cause noise. I saw snow because you say in the mountains and assume some snow.

Yea thats prob the case, there wasn't much of any snow but there are a couple that are slightly under exposed. Maybe Ill upgrade to lightroom3 and try its noise reduction lol.
