Is Coors Banquet still unpasteurized?

I know they used to advertise that they cold stored this beer throughout transporting...but I haven't heard anything about that in a long time. I assume they now pasteurize, because otherwise we would still be hearing about it in their advertisements. I have been very curious about this for a while and have spent quite a bit of time on google trying to figure it out with no conclusive results. So does anyone know if Coors original beer is pasteurized or not?
