What makes iced tea cloudy sometimes?

Question

Does not contain sugar. Only tea from tea bags and water.

Answer 1

sugar is not completely dissolved

Answer 2

It becomes cloudy because it's cooled too quickly. A reaction occurs - the tannins separate and float around the container giving the cloudy appearance.

Let tea sit for 5-10 minutes and SLOWLY add cold water. This will yield a clear, not cloudy tea.

Answer 3

the type of tea and how well it was brewed
