Is probably the most widely consumed beverage in the world.

two main varieties of Tea plant are those of INDIA and of CHINA:
Most teas are cultivated at a height of about 2000m and are picked in spring.
Tea originated in China in 3000BC and spread to Japan in about 780 BC. It was not grown in India until the 1840's and in Ceylon (now Sri Lanka) in 1867. Tea was brought to Europe in the 17th century.
At first tea was regarded as a purely medicinal drink but soon became popular with the aristocracy and then with society in general.
Although the shrubs can grow to 10ft high they are usually limited to 4ft so that the leaves can be easily picked by hand.
The downy terminal bud and the top two leaves are picked from the stem. The smaller & younger the leaves the better the tea.
THE GRADES OF TEA:
Orange pekoe: the highest quality - the tip of the bud
Pekoe shorter leaves without the bud
Pekoe souchong even shorter coarser leaves
Souchong leaves older still and rolled into balls

3. Oolong Tea
Which is semi-fermented

Manufacture takes place in 5 stages:
Withering - the leaf is dried & softened
Rolling - the cells of the left are broken down to release a mixture of constituents)
Moist fermentation 2-3 hours at 27°C
Desiccation 20 minutes at 90°C

The Coffee tree which bears small red berries that contain seeds known as coffee beans originally came from Sudan & Ethiopia but is now widely cultivated.
Earliest known date 1420. Venetians imported first coffee in 1615.
Two main species of coffee tree are
Coffea arabica - elongated , oval & flat beans which are mild & aromatic
Coffea robusta ( a. k. a. canephora) - smaller & more convex - contain 2.5 times more caffeine - produce a more full-bodied & bitter drink
these two varieties make up 95% of world production
Minor varieties include - Liberica, Excelsia
PRODUCTION OF COFFEE
1. The fruits are treated to remove pulp, the "green" coffee are graded & bagged.
2. Roasting: The beans are continuously stirred during the roasting process - the degree of roasting is a matter of taste the more the coffee is roasted the stronger & more bitter the resulting coffee. The range is from very light roast (popular in USA), medium roast (Italy & France) , High roast (Holland & Germany), very High roast (Middle East & Turkey)
3. Grinding: The fineness of the grinding depends on the method used to brew the coffee. Ideally it should take place just before the coffee is made.
Storage: Store in a sealed container in a refrigerator, N.B. coffee loses its aroma quickly after roasting.
Caffeine: This alkaloid gives coffee its stimulating quality
Types of Coffee:
Coffee can be divided into the country of origin & the degree of roasting as well as type of bean. The most famous producers are:
Brazil, Arabia, Columbia, Ethiopia, Mocha (India), Mexico, Costa Rica, Ivory Coast, Angola, Zaïre etc.
Viennese - coffee with the addition of fig essence
Decaffeinated. - with caffeine removed.
Instant - spray dried/freeze dried/liquid extract

COCOA & CHOCOLATE
The cocoa plant is a small tropical tree originally grown in Central & South America but now grown in largely in West Africa.
The fruit is a large pod 4-12inches in length and about 4 in. in diameter. It has a leathery rind and contains 25-75 seeds in 5 rows.
Two main species of Cocoa are Criolli & Forastero.
Fermenting to prevent germination to encourage enzymes which develop flavour.
Drying either in the sun or in drying chambers
Roasting to develop flavour & aroma and give even colour.
Winnowing - removes shell leaving NIBS
Alkalising (Dutch processing) - nibs are tumbled in a warm alkali solution further develops flavour
Grinding - nibs are ground into very small particles, this process releases a lot of fat called COCOA BUTTER and the mass becomes a thick syrup
Extracting - some of the fat is removed and the solid mass is pulverised and sieved leaving a fine powder.
Cocoa Powder: the powder resulting from the above process which can be made into a drink by adding hot water or milk.
Plain chocolate : the mass is mixed with sugar, refined and standardised (Conched) - set in slabs/bars this product is also known as Couverture
Milk Chocolate: as above with the addition of milk "crumb" that is condensed milk & mass reduced to powder form.
Drinking Chocolate: is prepared from chocolate powder or flakes with the addition of hot milk or water.
