Alcohol freezing point
Alcohol over 34% volume you can not freeze yourself.
Beer: -3 degrees Wine, sparkling wine: - 5 degrees Liqueur: with 23% and high water content - freezes the water, but not the spirit. Liqueur: with 23% and low water content (eggnog or similar) -10 degrees
Rule of thumb:
Volume % alcohol : 2 = freezing point in - C°. So 40% alcohol freezes at about -20 degrees.
It does not help to stretch the alcohol with water, it does not work.
