India requires all dust grades and 50% of the leaf and broken leaf teas to be sold at auction
Tata Tea Under Scrutiny Again
Shantha Chhetri, a former parliamentarian from Kurseong, has written to the offices of the Prime Minister of India and the Commerce Minister, raising concerns about Tata Consumer Products’ consumer packs. She said the company blends its tea with those from Nepal, which is unsafe for consumption and does not meet safety standards. She has urged the food safety regulator, FSSAI, and the Tea Board to test their tea for MRL levels of banned pesticides. The company responded that they do not import directly from Nepal. And that any Nepalese tea in blends is sourced from Indian traders. Tata explained that their teas are rigorously tested within the company and are deemed safe. In 2021, Tata Tea and Darjeeling were at loggerheads when the Tea Board prohibited blending imported teas with GI-protected Darjeeling, Assam, Kangra, and Nilgiri teas. A year later, this ban was lifted. The Telegraph
Indian Government Requires 100% of Dust to be Sold at Auction
The amendment of the Tea (Marketing) Control Order, 2003, will come into force from 1st April 2024. One of the directives is that 50% compulsory sale of tea and 100% sale of dust grades must be sold through public auctions starting 1st April. This order is targeted at estates in North India, including Arunachal Pradesh, Assam, Bihar, Himachal Pradesh, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, Uttarakhand, and West Bengal. Dust grades account for 25% of Assam and West Bengal tea production. Retail prices for CTC dust are currently Rs 160 to Rs 190 per kilogram (IndiaMART). The move is thought to support greater compliance of tea towards boosting exports. The mandate does not apply to many small-volume mini-tea factories. Industry stakeholders are divided in their opinion on this new move.

Assamica is One of Five Distinct Genetic Tea Populations
By Roopak Goswami
A study published in the Journal of Plant Beverage Research reveals new Camellia sinensis assamica varietal traits. Researchers from India and China have worked on this study using 150 SNP markers and population genetics tools to conclude that Assam tea is unique. Researchers identified five distinct genetic populations independently domesticated from a western cluster of wild tea trees rather than introduced from a single origin. The varietal grown in Assam differs from the eastern cluster grown in Yunnan. This new understanding presents new possibilities for cultivating new hybrids bred from Assam tea.
The Assamica specimen was collected in 1949 for Kew Royal Botanic Gardens.
While there is a reasonable consensus regarding China type (var. sinensis) and Assam type (var. assamica), the classification of Assam tea needs to be clarified. Scientists associated with the study say it is essential to understand further the genetic diversity and population structure in c. assamica for efficient conservation and use of Assam tea germplasm in crop improvement programs. The objectives were to understand the genetic diversity and population structure in the Assam tea germplasm from India and China and to assess the efficacy of the current classification system for tea.
The present study used 150 Single Nucleotide Polymorphism (SNP) markers to analyze a representative set of Assam tea sampled from Assam, India, and from four ancient tea gardens in China. SNP markers are the most efficient molecular markers, helping scientists locate genes associated with essential characters. A total of 252 teas sourced from Assam, India, and China were used in the investigation.
Scientists from China, the USA, and India employing cutting-edge techniques and population genetics tools have shown at least five distinct var. assamica populations in their primary gene pool. These include:
1. India var. assamica, which is distributed in Assam, India, 2. Cambod type from Indochina, but the exact origin and distribution are not yet identified, 3. China var. assamica from Southwest Yunnan (leaves from Jingmai and Mangshi), 4. Jingping, Honghe district, Yunnan and 5. Malipo, Wenshan district, Yunnan.
Assamica leaf
Assam growers contribute around 12% of the world’s tea annually and are known for the large quantities of second flush leaf harvested in May-June. Made tea is characterized by its boldness and robustness and is topped with classic malt and woody astringency flavors. It is valued for its rich taste and bright liquors and is considered one of the world’s choicest teas. Because of its high caffeine content, Assam tea is marketed as a breakfast tea.
The study says that despite the joint adoption of the two botanical varieties (C.s. var. sinensis and C. s. var. assamica) by the tea research community, the genetic basis for the current classification system for Assam tea germplasm has yet to be comprehensively clarified. Several studies based on molecular markers have provided contradictory results.
“Our result confirmed that the wild trees found in Assam are indigenous to Assam and ruled out the possibility that they were introduced from Southeast Asia or China.”
In general, tea in India Assam is known for its high polyphenol content, broad leaf, and adaptability to hot and humid climates. In contrast, the Chinese small-leaf variety is well known for its hardy adaptability to many environments, high theanine content, and small leaves.
“The main finding is that Assam tea is unique and has separate centers of origin. Although the Assam tea available in Yunnan in China has a bigger leaf size, it is different from the Assam tea available here in Assam,” writes Dr. Devajit Borthakur, a study co-author. Borthakur is a tea breeder and was the principal investigator at Tocklai when he did research in the USA.
“The specialty of Assam tea lies in its unique genetic architecture,” says Borthakur, who holds a doctorate from Zhejiang University, Hangzhou, China.
“A thorough understanding of the genetic architecture of the popular Assam clones, including 154 garden series clones and at the same time, their blending compatibility need to be worked out to exploit the uniqueness of Assam Tea. TV-23, the most popular tea clone, does not reflect the true Assam character as the clone is a hybrid between the Assam and Cambod types, he says.
“The diversity among the Assam type tea in different tea growing countries is yet to be exploited. In tea, 80% heterosis (the superior performance of a hybrid progeny over the parents) is reported. Thus, there is a huge potential to improve tea’s yield, quality, and tolerance capacity if the breeding program includes the diverse tea germplasm available in different tea-growing countries. “Mutual exchange of germplasm between Yunnan in China and Assam in India and inclusion of this germplasm in tea breeding program may open up new possibilities,” he said.
“In conservation of genetic diversity, the important issue is that there should not be any duplication. Otherwise, the population size will be too big, and expenses and time will be well spent on maintaining the duplicated germplasm. To avoid duplication, it is essential to understand the exact genetic architecture of the germplasm. The panel of 150 molecular markers developed in our investigation is sufficient to avoid duplication in germplasm conservation of tea,” Borthakur said.
There is no doubt that China is the first center of domestication for tea, which can be traced back more than 2000 years ago. However, the hypothesis was that new studies, including the present one, did not support domesticated tea dispersed from China to India and Southeast Asia. Local people in Northeast India and Southeast Asia also domesticated tea using their indigenous wild tea populations.
“Our result confirmed that the wild trees found in Assam are indigenous to Assam and ruled out the possibility that they were introduced from Southeast Asia or China,” researchers say.
Side-by-side comparison
The study showed that research is still needed on the wild teas in Assam, the neighboring Northeast Indian states, and the countries extending south of China. “The distribution of genetic diversity in the Assam tea germplasm must be systematically collected and analyzed. The panel of 150 SNP markers developed in this investigation will help accomplish the task efficiently,” Borthakur said.
A hundred and fifty years ago, tea exporters in China faced a dramatic shift in demand due to conflict on the high seas and fierce commercial competition. The emergence of India as Europe’s black tea supplier disrupted almost three centuries of Chinese dominance in the world’s most lucrative black tea market. China needed something new, a cream and sugar-friendly alternative to smoky old-fashioned Lapsang Souchong. That tea was Keemun (pronounced Chee-mun), a modern marvel rivaling Darjeeling at breakfast and the fragrant black Uva teas used in Ceylon breakfast blends.
Invented in 1875, the aromatic “qi hong cha” or Keemun black tea, grown in Qimen County, quickly rose to prominence, explains senior tea master Lilian Xia, President of the Canada Tea Institute. She joins Tea Biz to recount the legacy of a Chinese market-savvy entrepreneur, Yu Ganchen, the pioneer of Qimen tea, who developed the processing method for Qimen black tea and expanded its sales overseas.

Keemun, the Most Famous of China’s Black Teas Returns to Prominence
By Dan Bolton
Lilian Xia grew up in Shanghai, China, a region that has been the commercial hub of tea export for centuries. In China, tea artists are certified by local government officials who test their competency. Lilian is the first batch of senior tea masters and became the instructor at Shanghai Tea Institute and, simultaneously, the chief evaluator at the Shanghai Municipal Bureau of Labor. She helped compile the textbook “Senior Tea Artist” and lectures widely. She and her staff in Canada offer seven-level courses for adults and teens. The organization, she says, “is committed to popularizing tea knowledge, using tea as a link to strengthen cultural exchange among all ethnic groups, all classes, and all ages.” The society hosts educational tea parties, tea-themed activities, and tastings, including a public introduction to Runsi Qihong (Keemun) sponsored by the Anhui Guorun Tea Co. Lilian and I met at the Toronto Tea Festival in January.
Dan Bolton: Hongcha is experiencing a revival in China as millions line up daily for their milk tea. Keemun has a special place in the story of black tea as it is the first modern market-driven tea. Tea fragrance has always appealed to tea drinkers. Jasmine is one of the world’s oldest and most famous scented teas. European royalty and the upper classes preferred tea with milk and sugar, crumpets, and dainties, limiting sales of green tea and creating an opening that Keemun quickly filled. Will you share the history of this fascinating tea?
Lilian Xia: Let’s first talk a little bit about the history of black tea. In the early Qing Dynasty, around 1650, the Dutch and English first brought Chinese tea to the West. Most of the tea was from the Wuyi Mountains, near the eastern coast of Fujian Province. Exports were mainly green tea or oolong tea.
The tea, called bohea (an English pronunciation of Wuyi), is dried in wooden sheds, taking on a smoky flavor. Less well understood is that after pan-firing and rolling, the larger coarse leaves from the plant are pressed into wooden barrels and covered with cloth or bruised in cloth sacks to ferment before being fired a second time. During this step, the tea develops a unique “Keemun” aroma. The dark black leaves are then finished in bamboo trays suspended above smoking fire pits filled with hot coals from locally grown Pinus massoniana and slash pine. Adjusting the height of the tray influences the intensity of the aroma.
The tea known as zhèng sh?n xi?o zh?ng became rapidly famous within China as well, driven by the immense profits from its export. The English pronounced it Lapsang Souchong after the Fuzhou dialect for lap (pine) sang (wood) souchong (meaning small sort).
The tea had been traded for two hundred years by 1875 when Yu Ganchen was promoted to junior Mandarin (tax collector) in Fujian. He frequently dealt with tea exporters there and knew of the large quantities of black tea exported to the West.
Unfortunately, he was dismissed as unfit by the emperor. On returning to his hometown of Chizhou in Qimen County, in Anhui Province, he saw a nice environment spanning thousands of hectares where he could get good quality Zhuye tea leaves, so he asked himself, ‘Why not make black tea?’ Yu Ganchen returned to Fujian to study tea-making.

Using the hometown trees, Yu Ganchen invented a process for withering and pan-firing similar to that used in making Wuyi tea. He extended the withering and slowed oxidation to yield a more nuanced aroma, producing a better tea to sell to the West. Variations include Keemun Mao Feng, made from small leaves from the early harvest, and Keemun Hao Ya and Keemun Congou (broken leaf), which are more intense. Keemun Gongfu is preferred for use in tea ceremonies. Today, the best Keemun tea is made in Qimen County in Huangshan City, Anhui province, from leaves grown in Guichi, Shitai, Dongzhi, and Yixian.
Ganchen understood the needs of the Western people who begin their day with tea. The key modalities were color; Keemun is a deep red amber and distinctive fragrance with layers of flavor. Nowadays, many black teas are made in China, but Keemun remains the most popular.
Dan: The strong trade between China and the UK, dating to 1664, entered a rocky diplomatic period beginning in 1839 through 1842 as the first tea gardens were planted in Assam and Darjeeling and again in 1856 through 1960 when victory in the Second Opium War gave Western powers unfettered access to Chinese goods. Keemun marketers understood that winning competitions in the West and celebrity endorsements by royalty would appeal to Europeans and colonial tea drinkers in North America.
Lilian: He was quite familiar with the tea growers, exporters, and Importers from Western Fujian Province in Fuzhou City, so he contacted them and sold them to Western buyers. He opened a store in Yaodu to sell tea in Fuzhou and began marketing Keemun black overseas, where Indian black teas and Sri Lanka black teas were prominent.
A breakthrough occurred in 1915 in San Francisco at the Panama-Pacific International Exposition (an early World’s Fair). Keemun, competing with the finest Indian black and Ceylon teas from Sri Lanka, won the gold medal and became the number one choice of many Westerners, including the British and Americans.
The Queen and the royal family popularized Keemun in manuals describing the proper etiquette and preparation of afternoon tea. In London, it was known as the “queen of black tea” and is listed as one of the three most fragrant teas in the world. Keemun became quite famous in blends re-exported from London worldwide. The tea also won many national medals in China over the years. Download: Original Exposition Visitor’s Guide

Dan: The tea was so popular that Keemun became the main component in English breakfast blends. In 1879, more than 70% of the tea sold in London was from China. Darjeeling was an expensive luxury until the 1930s. People acquired a taste for Keemun during the years when Darjeeling was scarce. By 1900, China’s market share at the London tea auction had declined to 10%, but even then, the most popular Ceylon and Indian blends of Assam weren’t considered complete without at least 10-12% Keemun. Early mass-market blends, including Lipton and Twinings, featured African teas to give them color. Blenders added Assam tea for astringency. Why was Keemun so popular?
Lilian: Keemun Tea was popular because of its characteristics, like its unique aroma — it’s very special. Even now, in China, we distinguish black tea as either Keemun or not. So, what is Keemun’s aroma? It combines a floral note, a fruity note, and a honey-sweet taste.

Dan: The process that yields that aroma is very interesting.
Lilian: Yes, it starts with withering, then rolling, then fermentation and drying, all the uniform processes of black tea. So, how do we get this unique Keemun aroma?
There are two reasons. The first is definitely because of the tea tree breeds and where they are planted. The proper place is Qimen, a tea-growing region between the cool, fog-enshrouded Huangshan (Yellow) Mountains and the Yangtze River. The cultivar is called Zhu-ye-zhong. It is the same plant used to make Huangshan Maofeng, a grassy and vegetal full-leaf green tea plucked from old-growth trees.
Other critical steps involve slow fermentation and attention to drying. There’s a high-temperature step to reduce the moisture; then, it goes through lower-temperature drying, always 80 to 90 degrees. That low-temperature drying process develops those aromas.
We know that all those tea breeds produce aromatic compounds. Lower-temperature drying facilities develop those aroma compounds to bring out fruity and floral aromas.
Sugar substances and amino acids undergo the Maillard reaction, generating substances with a honey aroma. Many substances with fruity and floral aromas, such as lactones, terpenes, and alcohols, are generated, contributing to the distinctive Keemun black tea aroma characterized by hints of flowers, fruits, and honey. This unique scent is called Keemun aroma.
Making Keemun tea
Dan: One of the reasons Keemun is so important to the traditional Assam and Sri Lanka blended breakfast teas is because they are fired at a very high temperature in a furnace, which drives off aromatic compounds. Keemun adds a distinctive and pleasant aroma as you pour the hot water. Keemun tea drinkers describe the scent of honey, apple, and orchid.
Lilian: Yes, yes. Keemun is unique. Among all those Chinese varieties, more than one hundred black teas, Keemun remains the number one because of its unique aroma.
“Keemun is unique. Among all those Chinese varieties, more than one hundred black teas, Keemun remains the number one because of its unique aroma”
– Lilian Xia, President Canada Tea Institute
Dan: Will you tell listeners about the Runsi Qihong (Keemun Tea) brand? I was very impressed tasting the tea at the Toronto Tea Festival, and so were many others at your crowded booth.
Lilian: The tea is from what used to be a state-owned company and the biggest producer. It is called Anhui Guorun Tea Company Ltd. Mr. Yu Ganchen, who invented Keemun, owned the tea house that was the predecessor of the Guorun Tea Company. Runsi Qihong is their brand.
Before 1949, tea was mainly handmade and primarily sold to tea houses. But afterward, around 1950, China’s modern tea factories increased production, increasing exports. From the 1990s to the early 2000s, Chinese tea factories experienced another important reform, moving from state-owned to limited liability companies. In 2003, with the restructuring of its joint stock, Guorun became the most prominent company specializing in Keemun black tea. It is also the only factory producing diplomatic gift teas for official guests such as the Prime Minister from Britain or Queen Elizabeth.
Runsi Qihong has 12 EU-certified tea gardens and enjoys the title of national standard in China. So, as Keemun black tea is frequently chosen as a diplomatic gift, the highest grade is not premium; there is another grade called gift on top of the premium. Diplomats consistently choose Keemun black as the national gift.
Dan: That’s a prestigious role. According to the China Tea Marketing Association, 7,300 metric tons of Keemun tea are produced annually on 12,600 hectares of land. The tea is primarily for export, generating 5.52 billion yuan (about $808.6 million in US dollars in 2022). Will you explain the role growers play in the process?
Lilian: Guorun Co., Ltd. boasts significant productivity, employing highly mechanized tea garden management, plucking, and processing methods. However, producing the highest-grade teas involves meticulous handpicking and processing to ensure their unique, superior quality. For this, the company hires tea farmers skilled in the delicate task of tea picking, compensating them with labor fees. This blend of automation and traditional craftsmanship ensures the excellence of their tea.
Dan: Thanks for explaining that. So, let’s talk briefly about the Canada Tea Institute and its mission.
Lilian: We created the Canada Tea Institute in 2017 as a not-for-profit organization. We want to improve the tea culture and tea education. These days, we’re also trying to improve the economic development of tea. Most of our members are tea professionals and tea enthusiasts. We have our guiding principles. They are traditional spirits of tea masters, such as harmony, humility, genuineness, and equality. Those are the four guiding principles of our institute. So, we organize tea-related events and activities, such as tea master training programs and sometimes study trips. We have organized tea trips to some tea-producing areas in China, and hopefully, we can organize trips to other tea-growing countries, such as Japan.
During the past six years, CTI has organized over 100 tea-themed events involving more than 4,000 participants. By taking these steps, we’re working to diversify the Canadian tea market, making it more vibrant and dynamic.
Dan: I was happy to see all the young people at your booth. Will you briefly discuss your impression of young people and your role in educating those interested in your teas?
Lilian: I found many people of different ages interested in tea, and I was surprised that there are so many young people. I’ve noticed their enthusiasm for tea in the tea courses I’m giving young folks. They might not know all the ins and outs yet, but their interest is sky-high. They’re not just into the taste; they’re curious about blending their own, which is pretty much like creating something new, and they’re super keen on diving into the tea culture. It’s not just about, “Hey, this tea tastes good,” but more about, “What’s the story behind it? Why do we drink it this way?” They’re eager to explore different types of tea, how to brew them to get that perfect taste, and even which teawares best complement each tea. Honestly, it makes me really happy to see their passion for all aspects of tea, not just the flavor but the whole culture and creativity behind it.
Usually, in China, we use a gaiwan, a covered cup for brewing green teas, flower teas, etc. I also demonstrated Gaiwan brewing in class. Young students use those clear, translucent glasses because it lets them see the tea right inside; it piques their curiosity about the brewing process and its cultural significance.
I think it’s very, very amazing that since ten years ago, or even seven years ago, tea lovers have been aging. I mean, they love tea because they can feel the beauty of calm and simplicity. They are like 40 years old or 50 years old.
At that time, young people liked sweet drinks such as coffee and Coca-Cola, But now I see maybe it is because of the popularity of milk tea and bubble teas that many young people started to drink tea. Tea has become integrated into the daily lives of young people. From the bubble tea, they will pay attention to “This is green tea. This is black tea. This is oolong tea.” Then, they will seek more information about blended teas or different straight teas, I think it’s very good.

Disruptions due to the Red Sea crisis have extended tea delivery to the UK by 10-14 days
UK Retailers Concerned About Tea Supply
By Dan Bolton
Shipping company executives see no sign of improvement for vessels transiting the Red Sea, leading UK retailers and tea companies to take steps to minimize shortages.
As shipping costs surge, suppliers in Kenya and India face a more daunting challenge. Rates from Asia to Europe are up nearly five-fold, rising to $5,000 per 20-foot container. During the height of the pandemic, the expense of shipping containers of tea long distances exceeded the value of bulk tea within.
Three months into the crisis triggered by the war between Israel and Hamas terrorists, Yemen’s Houthi rebels continue their drone and missile attacks in both the Gulf of Aden and the Red Sea.
Executives of the largest shipping companies told Bloomberg TV that threat levels continue to escalate. The disruptions could last an entire year.
Maersk Chief Executive Officer Vincent Clerc told Bloomberg TV, “The amount and range of weapons being used for these attacks are expanding, and there is no clear line of sight to when and how the international community will be able to mobilize itself and guarantee safe passage.”
Half of the tea consumed in England is shipped from Kenya and India via the Suez Canal. This week, executives at Yorkshire Tea and Tetley Tea reassured the public they had implemented measures to minimize any disruption of the blending and manufacturing due to shipping delays.
A spokesperson for Tetley told the BBC “At the moment it’s much tighter than we would like it to be but we’re pretty confident we can maintain supply levels. Our priority is to maintain our consistent high levels of service, based on ordered and forecasted demand. We believe we can continue to deliver this, but acknowledge that this is a critical period which requires our constant attention.’
Spokesman Tom Holder of the British Retail Consortium, representing 200 retailers, reports temporary disruptions in the scheduled arrival of some black tea, but delays thus far amount to no more than a “blip.” Companies are adjusting orders and inventory to account for 10 to 14 additional days at sea. Sainsbury’s website assured customers of adequate supply but expressed concern should shipping firms experience lengthy delays.
According to Reuters, more ships are re-routing via the Cape of Good Hope than transiting the Red Sea via the Gulf of Aden.
BIZ INSIGHT – Britons drink about 100 million cups of tea daily, according to Sharon Hall, chief executive of the UK Tea and Infusions Association. The UK is the world’s fifth largest tea importer. Tea imports from outside the EU amounted to 104 million kilos in 2021. UK blenders export about 9.5 million kilos of tea valued at two million British pounds ($2.5 million in US dollars) annually, mainly to the European Union.

Assam budget allocates financing for tea worker housing
Budget Season and Aid for Tea
As State Governments announce their budget for the upcoming financial year, the tea industry has been waiting for news on its impact. So far, the Tamil Nadu government has announced an incentive of Rs 2 per kilo to members of the state-owned INDCO cooperative in the Nilgiris. This benefits about 27,000 small tea farmers attached to the INDCO factories. In Assam, 130,000 houses were to be constructed as per last year’s budget. This year, 10% of the houses are earmarked for tea garden workers. Additionally, funds will be earmarked towards payments of electricity bills in arrears in the tea communities. In West Bengal, the finance minister said 2,500 acres of unused land in tea gardens had been recovered and land rights granted to 23,000 workers in the Dooars. The housing scheme here continued to be in focus, as land rights and funds for house construction were included. Five tourism projects on four tea estates in the region have also been approved.
Iran Turns to Sri Lanka for Tea
The Hindu Businessline reportedthat a barter agreement between Iran and Sri Lanka will mean India will continue to lose in this market. In 2023, India’s tea shipment to Iran decreased from 54.45 mn kilos (2019) to 6 million (2023). Iran and Sri Lanka have entered a barter to settle the latter’s oil debt of $250 million for fuel purchases made in 2012. According to the agreement, Sri Lanka will supply tea worth $5 million monthly for 48 months, ending in September 2027.
