Tea drinkers will be stewing over potential rises to the price of a humble cuppa after a heatwave and floods dealt a blow to India’s harvest season.

Tea prices have been rising as a result of extreme weather, according to India’s Tea Board, with a kilogram fetching 217.53 rupees (£2.03), up 20pc from a year before.

India’s tea production in May plunged more than 30pc from a year earlier to 90.9m kg, its lowest for that month in more than a decade amid excessive heat and scant rainfall.

Costs have also risen as production has also been hit by the government’s decision to ban 20 pesticides, it said.

Prabhat Bezboruah, a senior tea planter and former chairman of India’s Tea Board, said: “Extreme weather events are hurting tea production. 

“Excessive heat in May, followed by ongoing flooding in Assam, are reducing output.”
