Black and Green Teas.

Either may be prepared at will from the same leaves; the difference lies in the mode of treatment. The earliest leaves are the tenderest and best flavored; later gatherings grow more woody and bitter. Black teas are spread in the air for some time after gathering, then roasted and rolled by hand, again exposed to the air, whereby they undergo a slight degree of fermentation, and finally are dried slowly over charcoal fires. The leaves for green tea are, as soon as gathered, roasted a few minutes in pans over a brisk fire, after which they are carefully rolled and thoroughly dried.
