Iran has a variable climate. In the northwest, winters are cold with heavy snowfall and subfreezing temperatures during December and January.
The Iranian wedding ceremony despite its local and regional variations, like many other rituals in the country goes back to the ancient Zoroastrian tradition. Though the concepts and theory of the marriage have changed drastically by Quran and Islamic traditions, the actual ceremonies have remained more or less the same.
The alcoholic drinks market in Iran consist of only non-alcoholic beer, as the law bans alcohol for Muslim citizens. Non-Muslim citizens (namely Christian and Jewish citizens) are allowed to produce alcoholic beverages for their consumption. Non-Muslim citizens are also allowed to bring alcohol into the country. However, despite complete prohibition for Muslim citizens, there is still widespread alcohol use across Iran.
