First, a little background. Crystal Head Vodka was founded by the OG Ghostbuster himself, Dan Ackroyd. In fact, his grandfather was a legitimate spiritualist, so Dan grew up knowing about, and believing in, ghosts.
When it came time to build his vodka brand, which is crafted in Canada, he decided to go with the skull motif, in a tribute to life and death, purity and rebirth.
Heavy stuff for a mixer.
