Three ways to make cold tea
Hot-brewed tea can be chilled over ice, and cold-brew tea can steep in the refrigerator. Sun tea sits for hours at mild temperatures, so refrigerated cold brew offers more control.
Make cold tea without leaving it in the sun
- Hot brew: steep the tea according to its packet, remove the leaves and chill promptly. Use more leaf if you plan to dilute it heavily with ice.
- Cold brew: use a clean covered container in the refrigerator. Steep for 6 hours or overnight, strain, then keep the finished tea refrigerated.
- Skip warm sun brewing. Mild temperatures do not reliably control bacterial growth. Iowa State Extension recommends refrigerated or hot-brew methods and using refrigerated tea within 3 days.
What does it taste like?
Hot-brewed iced tea can feel brisk and aromatic. Refrigerated cold brew is often softer and less bitter. Leaf, strength and sweetening still matter most.
What about caffeine?
Caffeine varies with the leaf, dose and steeping method. Herbal iced infusions may be caffeine-free.
Who might enjoy it?
- You want a cold alternative to coffee.
- You prefer softer, less bitter tea.
- You want to compare brewing methods at home.
