This tea is probably the most popular tea from Zhejiang, south of Shanghai.  The name 'gunpowder' was given to this tea because of its rolled leaves, which have the form of bullets.  If the rolled leaves are brewed with hot water they begin to crackle.  The tea can be brewed more than once, the first may be discarded if too strong, leaving a lower caffeine second brew with a more tender flavour.  In northern Africa the first brew is served with a mint leaf.
