Ichor Essence Wine was something that was originally meant for Celestials.
Normal wine would no longer affect cultivators, and the same could be said for Spirit and Immortal wine when Celestials consumed it. As such, they needed special celestial wines to get them intoxicated as well as to provide them with some great effects.
But among those, the Ichor Essence Wine was a bit special.
It was midway between the Immortal and Celestial wines, in that an immortal won't die from consuming it. It would simply get them quite drunk and if they were lucky, they could get some unexpected benefits.
The wine was made from a special substance called as Ichor which was found in some special mines. And when this Ichor was further refined, it would be turned into Ichor essence, which was a good resource for cultivation, not just for Immortals but also Celestials.
