Scientists Find Chemical Markers to Protect Darjeeling Tea
Scientists studied the smells and flavours of Darjeeling Tea.
They tested genuine tea from 45 estates.
They found 397 special chemicals that help create the tea’s aroma and taste.
Some of these chemicals may be present in Darjeeling Tea but not Nepal tea.
This could help identify tea that is incorrectly labelled or mixed with another tea.
The study examined teas from eight regions.
Researchers said the new testing found many more compounds than earlier studies.
The findings may give tea producers another way to protect the Darjeeling name.
Tea Research Association scientists identified 397 volatile flavour compounds in authenticated Darjeeling Tea samples.
Researchers said 20 to 30 compounds may distinguish Darjeeling Tea from Nepal tea.
Samples came from 45 Darjeeling estates and eight tea-growing regions worldwide.
The findings could supplement geographical-indication certification and existing traceability systems.
The research was funded by the National Tea Research Foundation and used newer analytical techniques.

- Where
- Samples were collected from 45 Darjeeling estates and tea-growing regions including Nepal, India, Sri Lanka and Africa.
- When
- The articles do not provide a specific date for the research.
- Why
- The research could help address alleged blending, substitution and mislabelling of cheaper Nepal tea as Darjeeling Tea.
Key facts
- Darjeeling samples
- Authenticated samples from 45 estates were analysed.
- Compounds in Darjeeling Tea
- Researchers detected 397 volatile flavour compounds.
- Potential distinguishing markers
- Around 20 to 30 compounds may differentiate Darjeeling Tea from Nepal tea.
- Sampling scope
- Teas from eight growing regions were examined.
- Total detected compounds
- About 49,000 compounds were identified across all sampled teas.
- Funding
- The research was funded by the National Tea Research Foundation of the Tea Board of India.
- Research relocation
- The Tea Research Association is relocating its Darjeeling office to the Darjeeling Tea Research and Development Centre in Kurseong.

“We are relocating our Darjeeling office to DTRDC Kurseong, where better and larger space is available for R&D facilities. This will ensure synergy between DTR&DC and the TRA on various issues relating to Darjeeling”

“There are 20 to 30 compounds which are found only in Darjeeling Tea and not in Nepal tea. There are also some volatile flavour compounds which are found exclusively in Nepal tea and not Darjeeling Tea”
