One of my academic interests, as I have mentioned in my C.V, is mysticism. If you are interested to read more about that, particularly its relation with viticulture see my joint paper, with Professor Tim Unwin in Journal of Wine Research:

Abstract:

This paper explores the symbolism of wine in medieval Persian poetry, focusing particularly on the works of Hafiz. It provides a brief overview of the archaeological and historical evidence pertaining to wine in Persia. This is followed by an account of medieval court poetry in Persia, before attention focuses explicitly on the work of Hafiz. This highlights the symbolism of wine particularly through an interpretation of Hafiz's ethical system, which is seen as being closely derived from 8th century Malamati philosophy.
