My experience is that wine won’t freeze until temps lower than 20F, so as long as they don’t sit outside overnight you should be fine.
I reckon you should know !
Checked the weather forecast — should stay in the 30s this week, may even get up to forty by weeks end… then a dip into the 20s at night. So let’s hope the trucks are warm. I get too many frozen pears from Harry and David !
In for one !
