If all the hipster New Agers knew where this originated and that it is (pst...witchcraft), they would shite their pants.

I started a Summer Solstice brewing event back home many years ago and got the biggest of smiles when I popped over to the Grove of the Ancient Order on facebook today and saw Pete posted this and some of my former students and fellow practitioners from back in the day are all commenting and wanting to start the tradition back up.
Not my exact recipe and I ain't posting my secret ingredients, so don't ask. And you wouldn't want to use my version for culinary purposes. hahahaha
