Types of Tea 1. Black tea - Fermented 2. Oolong Tea - Semi – fermented
3. Green tea - Un-Fermented
8
BlackTea Black Tea- Any variety of Camellia sinensis that undergoes a multi-step process after harvest of withering, rolling, oxidation and firing. Black tea requires a longer or fully oxidized enzyme process to create the character, color, flavor and aroma . Ex. Keemun, Darjeeling, Ceylon, Assam.
9
Oolong Tea Oolong Tea - Any variety of Camellia sinensis that undergoes a multi-step process after harvest of withering, rolling, oxidation and firing. Oolong tea’s enzymes are partially oxidized to create a liquor that ranges from reddish brown to green to pale yellow . Ex. Formosa oolong
10
Green Tea Green Tea – Any variety of Camellia sinensis that undergoes a process of firing or steaming immediately after plucking. This stops any enzyme action or oxidation of the leaves. The taste or character of green tea is heavily determined by the choice of clonal plant used, time of plucking, shoot maturity, geographic and weather conditions and cultivation method. Ex. Gun powder, imperial, Hyson, Chanmees.
11

Scented Teas These are made by adding flavouring like Jasmine flowers, rose petals, orange zest or mint leaves to tea during firing stage after which they are sieved out, for e.g earl grey, lemon scented ,cinnamon tea.
19
Production Methods 1. Traditional Orthodox Method 2. CTC Method
20
Production of Tea Plucking Withering Rolling Fermentation Firing
Sifting & Grading Sorting & Packaging
22
Traditional Orthodox Method Withering (Drying)
The plucked leaves are weighed and then spread out thinly or evenly on special racks 24 hours, where it is allowed to lose 50% of its moisture by evaporation
23
Rolling The leaves are put through rolling machines that break up the leaf cells. In this process the natural juices are released to come in contact with air.
24
Fermentation In this stage oxidation of tea tannin takes place. The rolled leaves are spread out on racks in cool humid room for about 3 hours, during this period the leaves become bright, coppery red because of oxygen and also develop flavour and aroma from the enzymes present in the leaf sap.
25
Firing The leaves are now fired in a current of hot,dry air for minutes.Firing helps in stopping of fermentation and turns the leaves to black , dry and crisp.
26
FIRING
27
Sifting and grading The dry tea is sifted, graded and packed into foil lined tea chests and sealed to protect the tea from moisture and odour. Method of producing green tea is similar to black tea except fermentation stage is omitted. For oolong tea partial fermentation is allowed.
28
Sifting & Grading
29
C.T.C (Cut, Tear and Curl) Method
The CTC leaves have pellet like appearance and always broken in size and have browner leaf than orthodox method.It produces strong liquor with less flavour. Leaves are processed through a special machine which cuts, tears and curls the withered leaves.
30
Grading of Black Tea Leaf tea Broken and small leaf teas Fannings Dust
31
Leaf teas grading are:4 SFTGFOP(super fine tippy golden flowery orange pekoe) TGFOP(tippy golden flower orange pekoe) FOP(flowery orange pekoe) OP(orange pekoe) P(pekoe) PS(pekoe souchong) Pekoe – Chinese word - leaf from tip.
32
Broken and small leaf teas Grading
Produced by CTC method. BOP (broken orange pekoe) FBOP(flowery broken orange pekoe) BP (Broken Pekoe) BPS (Broken Pekoe Souchong)
33
Fannings are small pieces of leaf
Fannings are small pieces of leaf.This grade includes BOP fannings,Pekoe fannings and fannings. Dust This is the trade name for Smaller leaf particle size.This grade yields stronger and darker brew with a shorter infusion time.
34
Tea bags Tea bags are nothing but blended tea in right proportion by experts having exact measured quantity.Tea bags exterior material doesn’t spoil the flavour of the tea. Tea bags are more expensive but they are more convenient and hygienic.
35
Making of Tea Tea is a unique beverage having aromatic and has highly volatile substances. Therefore it is important not to lose these in the process of making tea. For infusion the water should be at quite high temperature so that essential oils are released slowly.
36
Therefore tea should not be boiled,besides aromatic substances,tannin gets rapidly dissolved,i.e.if you boil tea;tannin being an alkaloid gives bitter taste,obstinate bitter flavour and black colour. Stored water is better to make tea as fresh water has more chlorine in comparison.
37
It is important to choose the right kind of teapot that retains the temperature for longer period.
The porcelain or china with shiny milky surface is considered to be good as there is less heat loss due to outer shiny silver surface,the chances of dropping temperature becomes less.

Benefits 3. In addition to the nutrients, tea provides about 70% of our daily fluoride intake. Fluoride is needed to support bone mineralization and protect teeth against dental caries. 4. Caffeine and polyphenols, the major non-nutrient components in tea has pharmacological effects.
43
Benefits 5. Scientific investigations have found the polyphenols could act as anti-oxidants after consumption, thus decreasing the risk of many diseases. Tea contains high amounts of polyphenols.
44
Benefits 6. Caffeine, the well-known stimulant, acts on the central nerve system, increases alertness and reduces feelings of drowsiness and fatigue. The caffeine in a cup of tea is less than half the amount found in a cup of coffee. Up to 300mg: of caffeine (8- 10 cups of tea) is considered moderate, with no evidence of harmful effects in the vast majority of the adult population.

47
Coffee Plant
48
Coffee Plant Coffee plant is an evergreen tree or bush which grows in subtropical and tropical climate. It is grown at 1850 m above the sea level. To grow coffee plant one requires rich soil,high rainfall along with hot climate. The part of plant is processed and used for making into coffee is the ripened berries which grow along the stem. The flesh of coffee fruits is removed and coffee beans are dried.
49
Varieties of Coffee Coffea arabica (Arabica coffee):
It is one of the best quality coffees. Its beans are uniform, bold regular sized and have good flavour. It is grown in India,Brazil,Colombia,Costa Rica,Kenya and Jamaica.
50
Coffea canephora (Coffea Robusta)
It is the second main type of coffee. The beans from the plant are usually smaller and of a lower quality with neutral flavour. It is grown is east and west Africa. Gives higher yield.
51
Coffea liberica It is third main type of coffee.
The beans are large in size but lack in quality. It is grown in Malaysia and Guyana.
52
Processing of Coffee The Dry Method
It is used in countries which do not have sufficient water. The coffee berries are spread out thinly in the sun and left till pulp shrivels tight on to the parchment.
53
Sun Drying
54
The berries are then put through hulling machine which removes pulp and parchment in one stage.
Beans processed in this way have traces of silver skin and lack attractiveness of washed Beans.
55
Coffee Bean
56
The wet method It is used in countries where there is sufficient water. The berries are processed through depulping machine, which removes fleshy part leaving the two seeds in their parchment jacket. They are then placed in large vats allowed to ferment for hours.
57
Fermentation During fermentation the coffee beans develop aroma any adhering pulp gets removed . The beans are then washed and dried in the sun. They are then put in machine for removal of parchment and sent for grading.
58
Sorting
59
Grading of coffee (varies from country origin)
# Bold or A Large,heavy,flat beans Second size or B Med. sized,heavy,flat beans Small or C Small size,heavy,flat beans # Peaberry Large,peaberry Peaberry Small,peaberry
60
#Elephant – Berries of above average size,often deformed in shape.
#Triage or T – Broken beans,usually of low quality. #TT Large broken beans. #CTT Mixed small flat and large broken beans.
61
Roasting of Coffee The green coffee bean has little or no flavour.
The flavour,aroma and colour is imparted by roasting of coffee bean. Roasting can vary from light to dark and is graded by colour . Light roast gives mild taste and dark roast gives bitter charateristics.
62
Grades of Roasting
63
Coffee grinding The roasted coffee bean is ground to allow the flavor, aroma and colour to be easily extracted by hot water. The ground coffee deteriorates more rapidly than the roasted coffee bean because of the high volatility of the flavoring oils.
64
Coffee Mixture Chicory a perennial herb is added to coffee.
Chicory when mixed with coffee produces a very strong and heavy coffee. At times figs are added to coffee. For ex. Bru & Sunrise.
65
Instant Coffee Instant coffee is pure coffee in soluble form and is made by brewing freshly blended roasted and ground coffee in large extractors where a very strong coffee concentrate is produced. The liquid is then atomised to a fine mist into a drying chamber containing hot air where the water evaporates from each tiny droplets leaving a pure coffee powder.
66
Caffeine-free coffee Caffeine is the alkaloid substance found in coffee due to which it has stimulating property. It can be removed upto 87% by putting green beans under vacuum. Caffeine free is suitable for heart patients. Ex. Nescafe Gold, Davidoff (Germany)
67
Popular Coffee Preparations
68
Espresso espresso is a concentrated coffee beverage brewed by forcing hot water under pressure through finely ground coffee. espresso often has a thicker consistency, a higher concentration of dissolved solids, and crema (foam) . As a result of the pressurized brewing process, all of the flavours and chemicals in a typical cup of coffee are very concentrate
69
Cappuccino Usually equal parts espresso, steamed milk, and frothed milk, often with cinnamon or flaked chocolate sprinkled on top. Some coffee shops will add more milk than that so that the customer will get a bigger drink out of the deal, but that makes the coffee itself far weaker

Cocoa It is a small tropical tree originally grown in South America and now commercially grown in West Africa. It needs a good soil, low altitude and high rainfall to grow. The fruit of the tree which grows on the branches as well as main trunk is used for making cocoa and chocolate.
79
The fruit is a large pod 4 inches-12 inches length, about 4 inches in diameter and has a hard leathery rind containing seeds in 5 distinct rows embedded in soft pulp.
80
Various Species of cocoa
Criollo Forastero The cocoa majorly comes from West Africa.
81
Processing of Cocoa Riped cocoa pods are collected, split open and the beans and pulp surrounding is scooped out and fermented under controlled conditions. Sweat boxes are used for fermentation where temperature is allowed to rise to degree centigrade.
82
Reasons for fermentation
To kill germs,prevent germination of the seed and decomposition of the bean. To encourage the enzyme reaction reducing bitterness and developing flavors. The beans absorb the liquid from the fermenting sugary pulp, which is then converted into alcohol and then into acetic acid.
83
The fermentation is stopped as soon as the mass of beans passes into the acid stage.
If fermentation is allowed to continue, it would develop unpleasant flavors and odors in the beans. Post which the beans are dried and roasted. Then the shells are removed (winnowing). Then at the final stage cocoa is extracted out.
84
Thank you.
