The optimal steeping time for Jasmine tea can vary depending on the type of tea and your personal taste preferences. However, in general, it is recommended to steep Jasmine tea for a shorter period of time, around 2-3 minutes, as steeping for too long can cause the tea to become bitter.
It's also important to note that the water temperature plays a role on steeping time, Jasmine tea should be steeped with water at around 80 to 85°C to prevent the tea from becoming too bitter or too weak.
It's best to start with a shorter steeping time and taste the tea every 30 seconds or so, adjusting the steeping time as needed to find the perfect balance of flavour for you. And always follow the instructions provided by the producer, they can give you more specific information on steeping time, temperature and amount of leaves to use.
