The big four British supermarkets, rightly and understandably, get a huge amount of press time and scrutiny, in both a positive and critical light.

It’s sometimes easy to forget, though, that there are also a huge variety of other, equally interesting retailers who are innovating and providing a supply of high-quality fruit and vegetables to their particular customer base.

This week we are shining the spotlight on some of those retailers, from ultra-high end practitioners Harrods and Selfridges - whose customers don’t bat an eyelid over shelling out £60/kg for cherries - to convenience-store specialist Budgens and a series of small, independent shops. We also drop into Waitrose’s Leckford Estate to find out how the supermarket is developing its understanding of grower issues.

It all makes for a fascinating retail picture at the moment. With the latest Kantar data suggesting both the premium stores and discounters are performing particularly well, it is clear there is much vibrancy in what exists beyond the biggest multiple chains.

They might not have the market share of the Tescos and Asdas of this world, but their stories and procurement strategies make them every bit as worthy of further attention.
