I recently went searching for a  wine to use in the “Cakes and Wine” part of our Wiccan rituals.   I went to the organic wine section of a local store since it seemed to me important the wine we used be as respectful of the earth in its production as possible.  A lover of Zinfandels, I was looking at
several bottles, and then discovered one using “Demeter”  grapes and grown biodynamically.   Which means well beyond
organic, and in the right direction. 
The back of the bottle pointed out that the grapes were grown with
attention to the “four lunar cycles.” The word “Demeter” cinched it.

I purchased Reinking’s 2007 Mendocino County Zinfandel.  I had found my wine, in my opinion a very good one.  Alas, they do not have
a web site.
