Turkish tea, also known as çay, is a popular beverage in Istanbul. It is a black tea that is brewed in a special double teapot called a çaydanlık. The tea is brewed in the upper pot, while the lower pot is filled with hot water to dilute the tea to the desired strength. Turkish tea is often served in small tulip-shaped glasses and is enjoyed throughout the day. It is a symbol of Turkish hospitality and is a great way to relax and socialize in Istanbul's tea houses and cafes.
