Before there was a share price, there was a trip to the Democratic Republic of the Congo and a question that sounds almost trivial: why does the tonic in a gin and tonic taste so bad?
Charles Rolls had spent his working life around gin. Tim Warrillow had spent his in advertising. They are the kind of pairing that makes a story, though what each gave up to join the other is not something their public record spells out. What it does show is the itch. A gin drinker could spend a fortune on a spirit and then drown it in a mixer full of preservatives and artificial sweeteners.
What almost nobody outside the drinks trade grasps is how small this was.
The pair wanted a tonic made with natural ingredients. That meant going to the source. The tonic they were chasing depends on quinine, and the tree it comes from has a name that became their brand. In India, the cinchona tree was known as the fever tree, and quinine mixed with soda water and sugar was the earliest tonic. The founders travelled to the Congo and then spent months experimenting with botanicals before they launched Fever-Tree Indian Tonic Water in 2005.
What almost nobody outside the drinks trade grasps is how small this was. The company was founded in 2004, and the first money came in 2006, when London & Lochside invested. There was no brand, no distribution, and a product that cost more than anything beside it on the shelf. The bet was that bartenders would care about the mixer once someone gave them a reason.
They did. Fever-Tree launched in the US and Spain in 2007 and got onto Sainsbury's and Tesco shelves in 2008. By 2011 it was in the Sunday Times Fast Track 100. In 2013 the founders sold 25% to Lloyds Development Capital and London & Lochside walked away. In November 2014 the company listed in London at 134p, valuing it at about £154m.
The years after were not a straight line. Reuters ran a headline in 2020 saying the shares were losing their sparkle as British tastes for premium tonic cooled, and the company has spent the years since leaning on America, where a distribution deal with Southern Glazer's put it in 29 states in 2018. In 2024 it even had to correct a news report that wrongly said it sponsored the Republican National Convention; it had only supplied free product.
Today Fever-Tree reports revenue of £228.5m (2024), and a market value of roughly £932m in May 2026, a long way from a premium tonic pitched at gin drinkers.
The lesson is easy to miss. They did not invent a new drink. They picked the least loved ingredient in a famous one and treated it as the product. Sometimes the opening is not a new category but the part everyone else decided was too small to bother with.
