Bigelow Tea's three new iced flavors in K-Cups are Unsweetened Iced Tea with Lemon, Perfectly Mint Iced Tea and Iced Tropical Green Tea. They are designed to be brewed hot over ice, using a Keurig K-Cup machine to prepare fresh-brewed iced tea at the touch of a button. Office coffee patrons simple fill a large non-glass cup with ice cubes, brew hot and stir to chill.
