...Sure, I'll take a poke into this thread... (and wildly thread-jack, most likely...)
Leaving aside the danger of accidentally poisoning yourself with ergot, what I find very interesting is the role of alcoholic beverages (with or without hallucinatory substances) in leading people toward a perception of deep mysteries.*
To an extent, that's something I still believe in. I had what I consider a transformative experience with a small glass of Laphroig Scotch this past spring, where I felt my place in the world, and was content.
Truly good beers do this as well, I feel. You appreciate the natural ingredients in it - the grains, the water, the "alchemy" of the yeast. I suppose, what I'm thinking is, that we brewers are the alchemists of modern life, and because of that we have the chance to show our non-enthusiast friends what it's like to understand the magic of brewing - and of drinking. A time and a place for everything...
(*Not saying these mysteries are real, or valid, or not-real, or whatever; only referring to the human experience and perception of these.)
PS - I'm half-way through a 720ml bottle of a Belgian Brown made with maple, yams, spices, etc... so if this post is a little wacky, that's my excuse
