Oolong
is a traditional Chinese type of tea somewhere in between green and black
in oxidation. Oolong tea undergoes a few delicate processes in order to
produce the unique aroma and taste. The leaves undergo a wilting process
whereby they are sun or air dried to remove some moisture. The leaves are
then bruised to create a larger surface for the oxidization process. The
leaves are then tumbled and fired to halt any further oxidation. Finally
the oolong leaf is cooled and dried to remove any excessive moisture. Oolong
teas generally contain approximately 3.75mg of caffeine per fluid ounce.
White tea is tea made
from new growth buds and young leaves which have been steamed or fired to
inactivate polyphenol oxidation, and then dried. The buds may be shielded
from sunlight. White tea tends to have the lowest concentration of caffeine
with levels as low as 2.0mg per fluid ounce.
