The delicate Jasmine flowers are plucked in the morning when the tiny petals are tightly closed. They are then stored in a cool place until night. Between six and eight in the evening, as the temperature cools, the petals begin to open. The flowers are mixed with either white, green or oolong tea. It takes four hours or so for the tea to absorb the fragrance and flavour of the Jasmine blossoms, and for the highest grades this process may be repeated as many as seven times. The result is a healthy and tasty tea full of the heady fragrances of Jasmine.
