Dairies in the capital told of a "phenomenal" upsurge in interest from younger customers at the start of the year amid growing public upset over plastic waste.
Both U.K.-wide company milk&more and east London dairy Parker Dairies have seen increased demand for glass bottles in 2018, citing David Attenborough's Blue Planet II as the "catalyst" for the new uptake.
The firms said younger consumers and families seem willing to pay more for the service in a bid to help the environment.
It comes amid conflicting reports of a resurgence in glass doorstep deliveries in the U.K.
While it was reported there was a 25 per cent hike in the number of deliveries in the U.K. over the last two years, Dairy U.K. told the Standard it could not confirm the figure.
The industry body said figures showed doorstep deliveries make up 3 percent of milk sales in the U.K. — around 1 million pints per day — and glass milk bottles make up 3 percent of all milk sales.
