Although sun tea relies on ambient heat rather than active boiling, it is sometimes grouped with cold brewing methods. For example,

this analysis comparing sun tea and cold brew tea methods

examines the differences in both safety and flavor.

Sun tea, while popular for making iced tea, has raised concerns due to the potential growth of bacteria when water is heated slowly over time.

The same analysis also documents testing of various brewing techniques and ultimately suggests that cold brewing may provide better results without relying on sunlight.
