Ethanol freezes at -114°C (-173.2°F).<br/><br/>The more ethanol there is in an alcoholic beverage, the lower it's freezing point. It's actually possible to "reverse distil" a beverage. Distillation involves heating the drink so that the alcohol boils off, and then condensing it back again. Alcohol having a lower boiling point that water. Reverse-distilation involves freezing the drink and pouring off the last liquid to freeze.<br/><br/>This is why adding ice to a glass of scotch makes the drink stronger - until the ice starts to melt.
