Kristina Kirilova has been named winner of the Bartlett Mitchell barista championship.
Kirilova, who works at a client site in Kent, beat five other finalists to the title having already bagged awards for best milk course and best espresso.
All baristas were tested on their coffee knowledge, grinding skills, coffee machine use and milk preparation techniques at the competition held at the Crypt in London's Clerkenwell.
Maria Barrottu, based in London, was awarded second prize while Kent-based Luis Marques was awarded third prize.
The judges included Ricardo Alesso and Dayanna Copini, both trainers for Bewley's, Graziano Moroni head of coffee for Bewleys and UKBC judge, and members of Bartlett Mitchell's management team.
Coffee brands manager Miguel Camara said: "The calibre of this year's finalists was impressive. Our baristas are going from strength to strength, learning more each year and taking inspiration from coffee and flavour trends.
"The final scores were very close. The winning competitor, Kristina Kirilova, was strong in every challenge. She demonstrated everything we look for in our baristas: passion, pride and personality."
Kirilova added: "I really can't believe it. I worked so hard and I just can't believe I managed to win. I'd like to thank all of my team and managers for supporting me throughout the competition and every day at work. This is amazing and I'm really shocked and happy."
As part of her prize, Kirilova will be going to the Specialty Coffee Association's (SCA) Barista Camp in Portugal for two days in September.
