Oolong tea is a traditional Chinese tea known for its unique flavor profile that lies somewhere between green and black tea due to its partial oxidation during processing. Let’s delve into the caffeine content of oolong tea, its health benefits, and other related aspects.
Understanding Oolong Tea Processing
Oolong tea is crafted through a meticulous process that includes several key steps:
- Withering: Freshly picked leaves are withered to reduce moisture content.
- Bruising/Rolling: The leaves are gently rolled to start oxidation.
- Oxidation: This controlled oxidation gives oolong its distinctive flavor and color.
- Firing: Leaves are heated to stop oxidation at the desired stage.
- Sorting and Grading: Finally, the leaves are sorted and graded according to quality.
This combination of methods results in a tea that displays the grassy freshness of green tea and the rich depth of black tea.
