The article examins one of the most attractive topics of the Islamic everyday-life history, which concerns Islamic ban of production and drinking wine and other alcoholic beverages. The author focuses on the distinct gap between the ethical and the juridical norm, and the fact, that this ideal has been constantly evaded from a very beginning of the Islamic history. Within this context, one can speak about a kind of „civilizational schizophrenia“. The fact of breaking rules of Islamic sharia was influenced by a couple of social and cultural factors: the level of political culture upon a variety of regions of Islamic caliphate, the prosperity of an agriculture and the dynamics of trade with wine as always demanded comodity, the misuse of Islam as an ideological means, by which the aspirations of various social and political phenomena have been enforced. The author refers to some of these factors in detail.
