The BBC’s Countryfile has visited a farm in Kent.
Presenter Adam Henson heard how blackcurrant grower John Hinchcliff is developing climate-resilient varieties to combat climate change in the UK at his farm near Canterbury.
The Countryfile team visited 300-acre New House Farm in Chartham on one of the hottest days of the year with temperatures reaching 35°C.
Mr Hinchcliff said: "The harvest is looking much better than predicted which is great news for us as growers, and great news for Ribena, who use 90% of Britain’s blackcurrant crop.
“We are proud to be able to supply our customers with 100% British fruit and work hard to ensure our blackcurrants maintain the same great quality and flavour every year.”
The episode is due to air on BBC One on Sunday, August 11, at 7pm.
