Alcoholic drinks
Egypt is a predominantly Muslim nation and alcoholic drinks are forbidden (haram) for strictly observant Muslims. That said, Egyptians tend to adopt a relaxed and pragmatic view towards alcohol for non-Muslims and foreigners. It is tolerated by the vast majority of Egyptians and consumed by a sizable number of them (including less strict Muslims - you may even be asked to "procure" drink for someone!) Alcoholic beverages and bottled drinks are readily available throughout the country (especially in larger towns and cities, as well as tourist centers). Please note, however, that public drunkenness (especially the loud and obnoxious variety) is definitely not appreciated - without caution, you may end up drying out in a police cell. Try to be a good ambassador: if you must get "tipsy", confine it to the hotel or very nearby! (It's actually quite rare to see drunken tourists, even in the most intense tourist areas...)
Stella (not Artois) is a common beer in Egypt. Other local brands are available, most a with higher alcohol variant that have claimed levels of 7% or even 9%..
Restrictions on Alcohol
Egyptian laws towards alcohol are officially quite liberal compared to most Islamic countries, except for the month of Ramadan when alcohol is strictly forbidden. During Ramadan only holders of foreign passports are allowed to buy alcohol, by Egyptian law. However, the enforcement of this law is by no means consistent. In tourist areas like Luxor, alcohol is sold even during Ramadan, and those who look like foreigners will not be asked to show passports or other documentation.
During Ramadan alcohol is often sold only in Western-style hotels and pubs/restaurants catering especially to foreigners. A few days of the year, as the day of the full moon the month
Before Ramadan, alcohol is completely banned. Also some hotels and bars catering to foreigners will stop serving alcohol during the Muslim holy month of Ramadan - phone ahead to make sure alcohol is still being served in order to avoid disappointment.
