Uncovering and Exploring the Facts About Tea
Yunnan Province-Home to King of Tea Trees
The World's Oldest Tree
China's Yunnan province is primarily a mountainous region with twelve tea mountains calling it     
 home, among them to the north of the Lancang (Mekong) River:  You Le, Ge Deng, Yi Bang, Mang
Zhi, and Man Zhuan, and to the south, Nan Nuo, Jing Mai, Meng Hai, Ba Da, and Meng Son.
Amid the mountains, growing within the lush for-
ests are ancient tea trees reportedly 500 and
1,000 years old.  There's even said to be one tree
on Nan Nuo Mountain called "King of Tea Trees,"
over a hundred feet tall and reputedly 1,700 years
old, making it the oldest plant on earth.

Yunnan
black teas are lush and assertive with a  
delicious combination of full body and maple
sweetness, and even a hint of pepper that's even-
ed out by plenty of sweet tips.

Both the
Keemun's chocolate flavors and Yunnan's
sweet maple flavors are formed by the Maillard re-
action, that occurs during firing.  It's caused when
amino acids and glucosides in the leaves combine
to form compounds called pyrroles and pyrazines,
both chemicals with sweet roasted flavors.

Yunnan and Keemun leaves both have different levels of amino acids.  Those in Yunnan leaves
form pyrazines that have a flavor reminiscent of cooked maple syrup, while those in Keemun
leaves have pyrroles, with the flavor of unsweetened cocoa but without the bitterness.

Yunnan province is home to 260 of 320 subvarieties of tea known
in
China.  Some of China's most flavorful teas come from the re-
mote area including Yunnan Buds of Gold and Yunnan Golden
Needles, the highest grades of Yunnan black tea with plenty of
long tips that give them a creamy, sweet, and malty flavor.

Like their Keemun cousins, Yunnan black teas contain plenty of
sweet glucose laden buds.  Starting off a light green, the buds turn gold during oxidation, the
same process that turns the tea black.  That's why many
China black teas have the words gold
or golden in their names, such as Yunnan Buds of Gold and Yunnan Golden Needles.

Both teas are made from an indigenous variety of large, broad leaf tea bushes and trees known
as dayeh.  This large leaf variety of tea was discovered by British botanist and adventurer,
Charles Bruce in the 1930's.

Dayeh is classified as a sub-variety of Camellia sinensis var. assamica, with large leaves that are
a golden reddish color both before and after brewing.

Yunnan's black teas have only been in production since 1939, but today Yunnan province is
China's largest black tea producer.

As the crow flies China's Yunnan province is not far from the
Assam region of India which touches
on the Tibetan Himalayas as does Yunnan.  Both regions also grow the same sub-species of tea,
Camellia sinensis var. assamica, to
make black tea.

This is a perfect example of two regions growing the exact same plant, but with two very differ-
ent tasting teas.  That's due to many factors, not the least of which are the varied manufacturing
techniques, but climate, soil condition, wind, rain, altitude-that and more combine as the
terroir,
determining what the final product will taste like.

Moving from the northwestern corner of Yunnan province, to the hot and steamy southwestern
corner where China's medicinal
pu-erh teas are grown.  The town of Puerh is a small market
area located in central Yunnan.  Oddly enough pu-erh teas aren't produced there, but in nearby
Xishuangbanna.  

                                              The town of Puerh was important, though, as it marked the             
                                                beginning of the Tea Horse Route as a distribution and collection    
                                                point of goods for those caravans travelling north and west.

                                               Xishuangbanna has a mild climate allowing for early spring tea       
                                                harvests beginning in late February.  In this more tropical area       
                                                the dayeh tea bushes are actually tea trees that have been pro-
ducing tea for hundreds of years, many of which have grown to heights of 20 to 30 feet tall.

The exact manufacturing process of China's pu-erh teas has been kept se-
cret for hundreds of years.  With little knowledge of pu-erhs outside of
Yunnan the tea was mainly collected by wealthy Hong Kong and Taiwanese
businessmen.

Today pu-erh tea is popular and in demand worldwide, from
Japan and
Southeast Asia, to Europe, especially France to Germany, and Eastern
Europe, and America.  Pu-erh is touted for its medicinal qualities, especially
in regard to
weight loss, known as the "slimming tea."
