Prime Minister Erdogan has questioned why Turkish people should drink alcohol
The Turkish parliament has approved controversial legislation to restrict the sale and advertising of alcohol.
The Islamist-rooted ruling AK party says the law will protect the population, particularly young people, from the harmful effects of alcohol.
Critics say it is a new move to impose an Islamic agenda on a secular, though predominantly Muslim, country.
The law bans the sale of alcoholic drinks between 22:00 and 06:00 and bans producers from sponsoring events.
To take effect, the law must be signed by President Abdullah Gul, but the politician - a member of the ruling AKP - is expected to do so soon.
Diageo Plc, the world's largest distiller of alcoholic beverages, has expressed concern about the legislation.
In 2011, Diageo bought Mey Icki, a producer of the traditional Turkish spirit raki, for $2.1bn (£1.7bn).
It said this week it had bought the company in the belief it was investing in a country "that encouraged foreign investment".

AKP politician Lutfu Elva, head of the planning and budget commission, defended the law, saying similar restrictions were in place in Scandinavian countries.
But Musa Cam, an MP from the main opposition party, the CHP, said: "No one can be forced to drink or not to drink. This is a religious and ideological imposition."
Quoted in an article in Turkish newspaper Hurriyet, he said: "This is not a struggle against the ills of alcohol but an attempt to redesign the society according to their [AK party] beliefs and lifestyle."
Hasip Kaplan, a Kurdish MP, warned the law would hurt tourism, which "can't recover easily once collapsed", the state-run Anatolia news agency reports.
