Rosenthal joins from Treasury Wine Estates, where he spent almost seven years and worked his way up to business sector controller for impulse and on-trade.
General manager Simon Doyle said: “We’re pushing on well with our strategic goals, focusing on building key brands with our most important customers in every sales channel.
“To ensure we retain absolute focus we identified a need for an overarching sales director role. I’m very pleased to welcome Jon to Concha y Toro, and I’m confident he will bring rigour, insight and energy to the business and help us in our long-term ambitions.
“Jon’s appointment is the final piece of our senior commercial team structure, with Clare Griffiths leading our marketing function, Andy Gale heading up new business development and Jim Elliot as account director for Tesco.”
Rosenthal added: “I’m delighted to be joining Concha y Toro at a time of strong growth for our brands in the UK. We have an ambitious but achievable vision and are already making great progress with our plan.
“CyT UK’s clear portfolio prioritisation, improving customer focus and investment in marketing our ‘hero’ wines is where I believe we will really add value for our key partners in the marketplace and enhance category value.”
