Next week, I'm taking a road trip from Los Angeles and spending a few days in Napa, where I'm sure I'll buy a few bottles. What precautions should be taken to ensure that the wines don't cook before I get them back home? I assume I should take them into the hotel room and not leave them in the car. Would it be advisable to keep them in a cooler with ice duirng the longer parts of the trip?
Thanks for any tips.
