Which has more caffeine ice tea or hot tea?

This is because:

* Brewing time: Hot tea is typically brewed for a longer period of time, allowing more caffeine to be extracted from the tea leaves.

* Temperature: The higher temperature of hot water extracts more caffeine from the leaves.

* Concentration: Iced tea is often made by diluting hot tea with water or ice, which reduces the overall caffeine concentration.

However, the caffeine content of both hot and iced tea can vary depending on factors such as:

* Type of tea: Black tea has the highest caffeine content, followed by green tea, oolong tea, and white tea.

* Brewing method: Different brewing techniques can affect caffeine extraction.

* Brand and product: Different brands and products may use different tea blends and brewing processes.

In general, if you're looking for a lower caffeine option, iced tea is often a good choice. However, if you prefer a stronger caffeine kick, hot tea is usually the way to go.
