Britain’s coffee habit is growing. Sales through coffee shops have surged 10.7% to £7.2bn in the past year, says UCC Coffee, supplier to Britain’s biggest high street names and retailers.

The growth has prompted UCC to spend £2.5m on increasing the capacity of its Dartford coffee roastery by 50%. The plant can now roast 12,000 tonnes of coffee a year, making it Britain’s biggest.

And Brits aren’t content to knock back just any old cup of Joe these days. “Knowledge of coffee has increased and people are more aware of different origins and blends,” says David Alexander, senior national account manager at UCC Coffee.

“The growth and expansion of coffee shops has driven this but we are even seeing places such as McDonald’s and Greggs focus more on their coffee offering, with the former including it as part of an advertising campaign.”

Food service isn’t the only focus for UCC. And the company, which supplies own label coffee to a number of the multiples and branded coffee for Lyons and ThreeSixty⁰, notes that tastes are getting increasingly sophisticated in the grocery market.

“People are becoming more confident in coffee preparation at home and more people are starting to get into grinding their own beans,” says Alexander. “In terms of the retail market, beans are where the growth is coming from – after pods of course – but from a very small base.”

He also notes increased interest from consumers in where their coffee comes from, which is creating a shift away from blends and into single-origin coffees. There is space for retailers to tap into this further, adds Alexander.

“Waitrose, for example, has 10 to 15 origins in its range but some of the other mults only have a few,” he says. ”When it comes to blends, French and Italian are the most popular, I think becasue of the strength of the Illy and Lavazza brands.”
