2016's strawberry solstice fell as the UK's strawberry pickers embarked on a bigger crop than ever before. Strawberries have become a supermarket staple - no longer a seasonal treat. But as our appetite for the berries has increased, production it seems, is becoming more complicated.

Californian strawberry farmers, who produce one of the biggest crops in the world, are facing some of the most challenging times in recent history. Back in post-Brexit Britain, fruit farmers are looking for assurance that they'll still attract pickers from the continent.

Yet the strawberry is interwoven into our culture like no other fruit, and when good, can be the flavour, scent and colour of summer. Chef Jeremy Lee, author Jane McMorland Hunter, farmer Marion Regan, professor Julie Guthman and winemakers Ron and Judith Gillies help Sheila Dillon unravel the surprising story of the strawberry.
