Why isn't beer served with ice? Well, the main reason is, the beer will get watered down as the ice melts – it's a problem that also extends to drinks that are served on the rocks, even though the coldness of the ice may help them to go down smoother. That's where the Beyond Zero system comes in. Instead of making ice cubes out of water, it makes them out of booze.
Invented by Kentucky-based entrepreneur Jason Sherman, the system actually consists of two devices – the Liquor Ice Maker and the Liquor Ice Storage Unit.
A liquor of the user's choice is first poured into the Maker, where it's cooled well below the temperature reached by a regular freezer, and formed into cubes. Exactly how that's accomplished is a trade secret, although the process takes just a matter of minutes.
Whiskey slushie, anyone?

The needed temperature is reachable using a regular closed loop with a compressor. The real trick is probably freezing the liquor without freeze distilling it. That and keeping your guests from hurting themselves with 'ice cubes' that melt at -30C.

The new CO2 (R744) based refrigeration systems would definitely have no problem freezing vodka.
R744 has some very good thermodynamic characteristics for sub-zero cooling.
Although its a little hard to work with because the high-side pressures are quite high. Design pressures typically 90 BAR. [danfoss.us]

Ignore above... Butthurt below made an observation which made my post above moot.
I had neglected the triple point of CO2. Old age, forgetfullness, and posting without researching, I suppose.
Sure seems I recall the triple point of CO2 being much lower... but sometimes one's memory plays tricks.

I stand guilty as charged.
