I am moving from Flagstaff, AZ to Spokane, WA. I have a wine collection of about 200-bottles many of which I consider ageworthy. Our movers have offered to transport the wine in the cab of the truck. There is a possibility that the truck may be stationary with our stuff for 1 to 2 days in potentially subfreezing temps. My concern is the wine being exposed to excessive cold temps. I know heat can damage wine but what about cold? Any suggestions?
