  The sake was most likely [supercooled](https://en.wikipedia.org/wiki/Supercooling). It was cooled below its freezing point, but there were no impurities to form ice crystals. When it was poured into a glass, as the author of that video suggests in his comment, it created turbulence that produced ice crystals to form, and once that process starts, accelerates until it is completely frozen. It is a fun experiment [to do yourself with just water](https://www.popsci.com/supercooling-instant-slushies).
