Black tea (also literally translated as red tea from various East Asian languages) is a type of tea that is more oxidized than oolong,yellow,white,and green teas. Black tea is generally stronger in flavour than other teas. All five types are made from leaves of the shrub (or small tree) Camellia sinensis, though Camellia taliensis is also rarely used. [2]
Two principal varieties of the species are used –the small-leaved Chinese variety plant (C. sinensis var. sinensis),used for most other types of teas,and the large-leaved Assamese plant (C. sinensis var. assamica),which was traditionally mainly used for black tea,although in recent years some green and white teas have been produced.
First originating in China,the beverage's name there is hong cha (Chinese :紅茶,"red tea") due to the colour of the oxidized leaves when processed appropriately. [1] : 127 Today,the drink is widespread throughout East and Southeast Asia,both in consumption and harvesting,including in China,Japan,Korea,and Singapore. [3] Similar variants are also available in South Asian countries.
While green tea usually loses its flavour within a year,black tea retains its flavour for several years. For this reason,it has long been an article of trade,and compressed bricks of black tea even served as a form of de facto currency in Mongolia,Tibet,and Siberia well into the 19th century. [4]
Unblended black teas are often named after the region in which they are produced. Different regions are known for producing teas with characteristic flavours.

Masala chai Indian (South Asian) spiced tea | Combines black tea,spices native to the Indian sub-continent,milk,and a sweetener such as sugar or honey;a beverage from India,possibly consumed for many centuries in the ancient kingdoms of the region before the arrival of the Europeans. Though the possibility of a pre-colonial tea culture still remains disputed,one can argue without any doubt that the post-independence Masala chai has played a significant role in India's modern tea consumption culture,making it the largest tea consumer in the world. [10] [ better source needed ] Masala chai has been widely recognised and adapted in the West by locals to their liking since its introduction by the British East India company,with changes in ingredients and the method of preparation to better suit western consumers. |
The tea is then ready for packaging.
Black tea is usually graded on one of four scales of quality. Whole-leaf teas are the highest quality,with the best whole-leaf teas graded as "orange pekoe". After the whole-leaf teas,the scale degrades to broken leaves,fannings,then dusts. Whole-leaf teas are produced with little or no alteration to the tea leaf. This results in a finished product with a coarser texture than that of bagged teas. Whole-leaf teas are widely considered the most valuable,especially if they contain leaf tips. Broken leaves are commonly sold as medium-grade loose teas.
Smaller broken varieties may be included in tea bags. Fannings are usually small particles of tea left over from the production of larger tea varieties,but are occasionally manufactured specifically for use in bagged teas. Dusts are the finest particles of tea left over from production of the above varieties,and are often used for tea bags with very fast and harsh brews. Fannings and dusts are useful in bagged teas because the greater surface area of the many particles allows for a fast,complete diffusion of the tea into the water. Fannings and dusts usually have a darker colour,lack of sweetness,and stronger flavour when brewed.
Generally,one uses 0.08 ounces (2.26 g) of tea per 8 US fl oz (237 ml) of water. [14] [ better source needed ] Unlike green teas,which turn bitter when brewed at higher temperatures,black tea should be steeped in water brought up to 212 °F (100 °C) for 3–5 min. [15] [ better source needed ]
Whole-leaf black teas,and black teas to be served with milk or lemon,should be steeped four to five minutes. [16] The more delicate black teas,such as Darjeeling,should be steeped for three to four minutes. The same holds for broken leaf teas,which have more surface area and need less brewing time than whole leaves. Longer steeping times makes the tea bitter (at this point,it is referred to as being "stewed" in the UK). When the tea has brewed long enough to suit the drinker's taste,it should be strained before it is served.
A cold vessel lowers the steep temperature;to avoid this,the brewing vessel is rinsed with water at a temperature of at least 90 °C (194 °F) before brewing.
The ISO Standard 3103 defines how to brew tea for sensory testing. [17] This standard is not meant to define the proper method for brewing tea intended for general consumption,but rather to document a tea brewing procedure where meaningful sensory comparisons can be made.[ citation needed ] This mix is thus more than twice as concentrated for normal consumption.
Black tea contains 2 to 4 percent caffeine. [18] The caffeine content of tea is affected by factors such as processing and brewing time. Typically,an 8-US-fluid-ounce (240 mL) cup of black tea without sweeteners or additives contains 47 mg of caffeine,and negligible quantities of calories and micronutrients. [19] [20]
The visible film often formed on black tea consists of oxidized polyphenols and calcium carbonate,and is therefore more pronounced for tea brewed with hard water. [21]
Black teas from Camellia sinensis contain flavonoids,which are under preliminary research for their potential to affect blood pressure and blood lipids as risk factors for cardiovascular disease. [22] Long-term consumption of black tea only slightly lowered systolic and diastolic blood pressures (about 1–2 mmHg). [22] [23] Black tea consumption may be associated with a reduced risk of stroke,but there is only limited research to evaluate this possibility. [24] [25]
Meta-analyses of observational studies concluded that black tea consumption does not affect the development of oral cancers in Asian or Caucasian populations,esophageal cancer or prostate cancer in Asian populations,or lung cancer. [18] [26] [27] [28]
Oolong is a traditional semi-oxidized Chinese tea produced through a process that includes withering the leaves under strong sun and allowing some oxidation to occur before curling and twisting. Most oolong teas,especially those of fine quality,involve unique tea plant cultivars that are exclusively used for particular varieties. The degree of oxidation,which is controlled by the length of time between picking and final drying,can range from 8% to 85% depending on the variety and production style. Oolong is especially popular in southeastern China and among ethnic Chinese in Southeast Asia,as is the Fujian preparation process known as the gongfu tea ceremony.
Tea is an aromatic beverage prepared by pouring hot or boiling water over cured or fresh leaves of Camellia sinensis,an evergreen shrub native to East Asia which probably originated in the borderlands of southwestern China and northern Myanmar. Tea is also made,but rarely,from the leaves of Camellia taliensis. After plain water,tea is the most widely consumed drink in the world. There are many different types of tea;some have a cooling,slightly bitter,and astringent flavour,while others have profiles that include sweet,nutty,floral,or grassy notes. Tea has a stimulating effect in humans,primarily due to its caffeine content.
Green tea is a type of tea that is made from Camellia sinensis leaves and buds that have not undergone the same withering and oxidation process which is used to make oolong teas and black teas. Green tea originated in China,and since then its production and manufacture has spread to other countries in East Asia.
Lapsang souchong or Zhengshan xiaozhong is a black tea consisting of Camellia sinensis leaves that is smoke-dried over a pinewood fire. This smoking is accomplished either as a cold smoke of the raw leaves as they are processed or as a hot smoke of previously processed leaves. The intensity of the smoke aroma can be varied by locating the leaves closer or farther from the source of heat and smoke or by adjusting the duration of the process. The flavour and aroma of smoked lapsang souchong is described as containing empyreumatic notes,including wood smoke,pine resin,smoked paprika,and dried longan;it may be mixed with milk but is not bitter and usually not sweetened with sugar. The tea originates from the Wuyi Mountains region of Fujian and is considered a Wuyi tea. It is also produced in Taiwan. It has been labelled as smoked tea,smoky souchong,tarry lapsang souchong and lapsang souchong crocodile. While the tea leaf grading system adopted the term souchong to refer to a particular leaf position,lapsang souchong may be made with any leaf of the Camellia sinensis plant,though it is not unusual for the lower leaves,which are larger and less flavourful,to be used as the smoking compensates for the lower flavour profile and the higher leaves are more valuable for use in unflavoured or unblended teas. In addition to its consumption as a tea,lapsang souchong is also used in stock for soups,stews and sauces or otherwise as a spice or seasoning. Beginning in the early 21st century,an unsmoked variety of lapsang souchong was developed in the village of Tong Mu Guan in the Wuyi mountains. The unsmoked variety has become increasingly popular,particularly in the Chinese domestic market.
Pu'er or pu-erh is a variety of fermented tea traditionally produced in Yunnan Province,China. In the context of traditional Chinese tea production terminology,fermentation refers to microbial fermentation,and is typically applied after the tea leaves have been sufficiently dried and rolled. As the tea undergoes controlled microbial fermentation,it also continues to oxidize,which is also controlled,until the desired flavors are reached. This process produces tea known as hēichá (黑茶),literally "black tea",though the term is commonly translated to English as "dark tea" to distinguish it from the English-language black tea.
White tea may refer to one of several styles of tea which generally feature young or minimally processed leaves of the Camellia sinensis plant.
Crush,tear,curl is a method of processing tea leaves into black tea in which the leaves are passed through a series of cylindrical rollers with hundreds of sharp teeth that crush,tear,and curl the tea into small,hard pellets. This replaces the final stage of orthodox tea manufacture,in which the leaves are rolled into strips. Tea produced using this method is generally called CTC tea or mamri tea.
In the tea industry,tea leaf grading is the process of evaluating products based on the quality and condition of the tea leaves themselves.
Camellia sinensis is a species of evergreen shrub or small tree in the flowering plant family Theaceae. Its leaves,leaf buds,and stems can be used to produce tea. Common names include tea plant,tea shrub,and tea tree.
Although health benefits have been assumed throughout the history of using Camellia sinensis as a common beverage,there is no high-quality evidence that consuming tea confers significant benefits other than possibly increasing alertness,an effect caused by caffeine in the tea leaves. In clinical research conducted over the early 21st century,tea has been studied extensively for its potential to lower the risk of human diseases,but there is no good scientific evidence to support any therapeutic uses.
Assam tea is a black tea named after Assam,India,the region of its production. It is manufactured specifically from the plant Camellia sinensis var. assamica (Masters). Assam's people tried to plant the Chinese varieties in Assam soil but did not succeed. Assam tea is now mostly grown at or near sea level and is known for its body,briskness,malty flavour,and strong,bright colour. Assam teas,or blends containing Assam tea,are often sold as "breakfast" teas. For instance,Irish breakfast tea,a maltier and stronger breakfast tea,consists of small-sized Assam tea leaves.
Nilgiri tea is a drink made by infusing leaves of Camellia sinensis that is grown and processed in the Nilgiris district in Tamil Nadu,India. The leaves are processed as black tea,though some estates have expanded their product offerings to include leaves suitable for making green,white and oolong teas. It is generally described as being a brisk,fragrant and full-bodied tea. The region produces both rolled and crush,tear,curl tea and it is predominantly used for blending. Nilgiri tea is also used for making iced tea and instant tea.
Gunpowder tea is a form of tea in which each leaf has been individually rolled into a small pellet. Its English name comes either from some resemblance of the pellets to gunpowder,or from a phrase in Chinese that phonetically resembles the word "gunpowder". This rolling method of shaping tea is most often applied either to green tea or to oolong tea.
Bai Mudan is a type of white tea made from plucks each with one leaf shoot and two immediate young leaves of the Camellia sinensis plant. Bai Mudan is sometimes preferred by white tea drinkers for its fuller flavor and greater potency than the other major type of white tea,Bai Hao Yinzhen. The latter is made purely with leaf shoots,and so it is comparatively softer and more subtle. The typical taste of Bai Mudan is a result of both the processing and the tea plant cultivars employed in the production.
Darjeeling tea is a tea made from Camellia sinensis var. sinensis that is grown and processed in Darjeeling district or Kalimpong district in West Bengal,India. Since 2004,the term Darjeeling tea has been a registered geographical indication referring to products produced on certain estates within Darjeeling and Kalimpong. The tea leaves are processed as black tea,though some estates have expanded their product offerings to include leaves suitable for making green,white,and oolong teas.
Canned tea is a relatively recent method of marketing tea which has been sold traditionally as leaf tea and also,for the last 100 years,in tea bag form. It utilises the canning process to produce a ready made drink. Perceived advantages includes ease of use and the possibility of additives;the disadvantages are the cost of shipment and a lack of freshness.
Tea processing is the method in which the leaves from the tea plant Camellia sinensis are transformed into the dried leaves for brewing tea.
Tea is a major cash crop that is grown in Kenya. Kenyan tea has been the leading major foreign exchange earner for the country.
Teatulia is a privately owned tea company based in Denver,Colorado. Teatulia is named after the Tetulia region in Northern Bangladesh where the company grows and produces its teas. It is the first USDA-certified organic tea garden in Bangladesh and the first tea in the United States that is imported from Bangladesh.
Food grading involves the inspection,assessment and sorting of various foods regarding quality,freshness,legal conformity and market value. Food grading is often done by hand,in which foods are assessed and sorted. Machinery is also used to grade foods,and may involve sorting products by size,shape and quality. For example,machinery can be used to remove spoiled food from fresh product.
