The move will raise Codorníu's profile in the Chilean category. Its portfolio covers a range of price points from £4.99 for the Terra Andina range to more than £20 for top level Santa Rita wines.
Claro has completed restructuring and investment programmes to prepare for the UK launch.
UK commercial director Richard Leaver said: "The joint partnership with Codorníu will maximise our position in the off-trade and allow us to play a more relevant role in the UK. We also want to have a mix of 35 per cent of our sales at reserva level (£6.99+) ."
Codorníu will handle Claro's brands in the off-trade, and Terra Andina and Doña Paula in the on-trade, but Berkmann Wine Cellars and Stevens Garnier will continue to distribute Santa Rita and Carmen in the on-trade respectively.
