How popular is Alcohol in Turkey?

I know that Alcohol is widely available and Turkey and is very popular among secular Turks. In Fethiye and Antalya and Izmir, Supermarkets and Shops have a very large variety of Alcohols(Beers, Wines, Scotch and Tennesee Whiskies, Tequila, liqueurs etc, you name it). Are the variety of Alcohols mostly aimed at locals or tourists. Is Alcohol also popular among people in South Eastern or Eastern Turkey or just in the west?
