Does Eggnog Freeze?

So we had Thanksgiving yesterday and one guest brought over about a gallon of eggnog in 4 of those 1/4 gallon paper jugs. 3 of them were unused and we didn't have room in the fridge. They ended up just outside the front door on the enclosed porch.

This morning I woke up to 16 degrees outside. I pulled the eggnog in and it wasn't frozen! It was pretty cold though!

My thermostat allows the house to go down to 55 at night.

Given my front door is the original 90 year old one, do you think eggnog freezes far below 32 or my front door is loosing a heck of a lot of heat?

I don't think so. I posted this on my my woodworking board and they suggested that the sugar would lower the freezing temp some. I'm hoping that the enclosed porch had an effect on it too. I'd hate to think my house is loosing that much heat out the front door.

I remember there was something from chemistry class stating each mole of solute lowered the freezing point some amount, but figuring out how many moles of solute in eggnog is beyond my capabilities! :lol:
