Rubicon built an entire brand on flavours the rest of the British soft drinks aisle wasn't touching in the 1980s: mango, guava, lychee, passionfruit.
Founded in 1985 on flavours nobody else was selling
Rubicon launched in the UK in 1985, at a time when the mainstream soft drinks market was almost entirely orange, cola, and blackcurrant. Its founders bet on fruit that was common in South Asian, Caribbean, and African kitchens but almost absent from British supermarket shelves, and built the whole range around it.
Mango first, everything else after
- Mango juice drink — Rubicon's flagship flavour, closely associated with Alphonso-style mango and still the product most people mean when they say "Rubicon."
- Guava — the second signature flavour, similarly rare on UK shelves outside specialist grocers before Rubicon.
- Lychee, passionfruit and others — added over time to extend the same positioning: fruit the mainstream brands weren't bothering with.
Why it became a fixture in diaspora communities specifically
Because the flavours were already familiar rather than novel to South Asian, Caribbean and West African households, Rubicon found a genuinely loyal customer base in those communities well before "exotic" fruit flavours became a wider trend in UK drinks — it wasn't chasing a trend, it was serving a market that already existed and had been underserved.
Now part of the Irn-Bru company
A.G. Barr, the Scottish company behind Irn-Bru, bought Rubicon in 2007-2008, folding the exotic juice specialist into a much larger British soft drinks group while keeping the branding and flavour range essentially intact.
