I don't Drink anymore. But I don't recall Vodka Freezing Solid when I did.
Here's a Question for you...
How come the Frozen Orange juice concentrate I buy will stay good for Years? But the OJ I buy in the Store only lasts for about a Week in the Frig?
The OJ concentrate Isn't frozen Solid. More of a Slurry. At lest in my Freezer it is.
Kinda like what my Nicotine Base looks like when I Freeze it.
OJ is water, not alcohol based, so it does freeze. Good per se, no, it looses vitamin C. Yes, it'll still have good flavor, but it'll lose the flavonoids present in the juice when squeezed.
Here's a chart of temps PG needs to freeze. If you store it in a big container you'll need low temps... but, still, again, what for?!?
Propylene Glycol based Heat-Transfer Fluids
Certain things shouldn't be frozen. Keeping them at 3C is EXACTLY the same. And no, Vodka doesn't freeze in a regular freezer.
