A curious revolution is brewing in India. The nation’s tea gardens, long known for their robust chai, are now being eclipsed by a different sort of harvest: butterfly pea flower. This vivid blue bloom, steeped in water, produces a striking turquoise infusion that has captured the imagination of a new generation. Cafes from Mumbai to Kolkata now serve it as the ‘blue gold’ latte. And British trade officials are watching closely, keen to carve out a slice of this emerging market.
The butterfly pea flower, or Clitoria ternatea, is not a recent discovery. It grows wild across Southeast Asia and has been used for centuries in traditional medicine and natural dye. What has changed is its commercialisation. In India, a wave of start-ups is transforming the flower into syrups, powders, and ready-to-drink beverages. The colour is the main draw. It changes from blue to purple when lemon juice is added, creating a visual spectacle that social media loves. But there is more to it than Instagram appeal. The flower is rich in antioxidants and is marketed as a natural stress reliever. A 250 ml bottle of blue gold tonic can sell for 150 rupees, about £1.45. That is more than double the price of a standard soft drink.
For British trade officials, the opportunity lies in packaged exports. India’s middle class is growing and its thirst for premium, health-centric beverages is rising. James Edwards, a trade advisor based in Delhi, told me: “We are looking at how British companies can get involved. There is strong interest in high-quality herbal teas and natural extracts. The UK has expertise in branding and food safety standards that could be attractive to Indian producers looking to export.” The UK India Business Council has already hosted seminars on export logistics and certification.
But there are hurdles. The supply chain is fragmented. Most butterfly pea flowers are still harvested by small farmers in rural Uttar Pradesh and Tamil Nadu. They dry the petals in the sun and sell them to local aggregators. Quality control is inconsistent. One start-up founder, Priya Sharma, explained: “We have to test every batch for moisture content and colour strength. A single rainy harvest can ruin our supply.” Her company, Blue Bloom Beverages, now contracts directly with a farmers’ cooperative to ensure consistency. She pays them a premium 20 per cent above local market rates.
There is also the question of intellectual property. Some Indian firms are trying to trademark ‘blue gold’ as a geographic indication, similar to Champagne or Darjeeling tea. That could complicate negotiations for foreign importers. British officials are treading carefully. They stress that any deal must be fair to Indian producers. “We are not here to plunder,” Edwards added. “We want partnerships that benefit both sides.”
Back in the UK, interest is percolating. A handful of specialty tea shops in London and Manchester now stock butterfly pea flower blends. They sell for £6 per 50 grams. That is steep for a kitchen table budget. But Sarah Jenkins, a consumer from Leeds, said she buys it as a treat. “It’s beautiful and it feels exotic. I mix it with honey and ginger.”
The real prize, however, is the mass market. British supermarkets could offer butterfly pea flower as a tea bag or a concentrate if supply scales up. But that requires investment in processing facilities and cold chains. Indian start-ups are pushing for a national standard for blue gold beverages. They have formed an industry body to lobby for subsidies on drying equipment. The government has taken notice. The Ministry of Food Processing recently allocated 50 crore rupees, about £4.8 million, for research into value-added products from indigenous flowers.
For now, the blue gold drinks industry remains a boutique affair. But it is growing. Exports of butterfly pea flower products from India rose by 35 per cent in the last financial year, according to trade data. The top destinations were the United States, the United Arab Emirates, and the United Kingdom. British trade officials believe that with the right support, exports could double within three years. They are planning a trade mission to India next quarter to meet producers and finalise standards.
This is not just about a pretty drink. It is about rural livelihoods, fair trade, and the kitchen table economics of what we choose to sip. The blue gold craze shows that innovation can come from the most unlikely places. And that the UK, for all its talk of global Britain, must ensure that the benefits flow back to the fields where the flowers are picked.
