Caffeine Content in Unsweetened Iced Tea
It seems like unsweetened iced tea is making a comeback. More and more people are drinking this refreshing and healthy tea over sugary beverages. But how much caffeine does it contain?
Caffeine Varies According to Plant Variety and Brewing Method
Caffeine content in brewed tea can vary depending on the plant variety and how the tea is prepared.
• White tea has the least amount of caffeine with an average of 6-60 milligrams per cup.
• Green tea is the middle range with an average of 20-60 milligrams per cup.
• Black tea has the most caffeine with an average of 30-70 milligrams per cup.
Iced Tea Caffeine Content Varies
Iced tea caffeine content is roughly the same as regular hot tea but can vary depending on how the tea is brewed. A single teaspoon of tea brewed in hot water and served cold can contain 40-50 milligrams of caffeine. However, if the same teaspoon of tea is steeped for an extended period of time the caffeine content can increase to 90-100 milligrams per cup.
Keep in Mind Sugar Content
Although unsweetened iced tea does not contain added sugars, it is important to keep in mind the caffeine content of the tea. Too much caffeine can lead to various health issues, including insomnia and elevated blood pressure. It is recommended that you limit your intake of caffeine to 400-500 milligrams per day.
Therefore, it is important to be mindful of caffeine intake if you plan on drinking unsweetened iced tea.
