Coffee is one of the most famous drinks in the world and its admirers are those who were responsible for popularizing the drink as a beverage in the Ottoman Empire. It is assumed that it entered the Ottoman soil after the conquest of Mamluk Egypt. In the mid-16th century, when it arrived to Istanbul, it got a great response which also spread to the European lands approximately one hundred years later. Culture, tradition, and customs that have developed around coffee drinking were not always positively accepted. Nevertheless, they have mostly managed to be maintained to this day. Coffeehouse, a new social institution that occupied the public space, caused controversies that were justified through numerous different reasons. Comparisons with wine, carbonization, poor physical impact on the body, deterrent to prayer, and so on are just some of the arguments why, according to the religious circles, coffee had to be banned. However, the bans did not last long because by that time the culture of coffee drinking, that is Turkish coffee, had already been firmly settled into society.
