Ehrmanns is introducing two new Faritrade wine ranges from the newly-certified Chilean winery CVC.
In the impulse and multiple off-trade, Los Unidos will replace Los Robles, the winery swallowed by Cono Sur after it hit financial difficulties last year.
Los Troncos will replace Los Almendros in Ehrmanns' exclusive portfolio for the on-trade and independent wine merchants.
Ehrmanns managing director Mark Chapman said: "Unlike a number of Fairtrade brands, the growers will have equal ownership of the brands with Ehrmanns.
"We believe it is important to ensure that the growers, their families and their communities, benefit not only immediately from the Fairtrade premium, but also long-term from the creation of brand value in the UK and European markets."
The Fairtrade premium will be used to fund educational programmes and medical facilities.
Both ranges are available in bottles, while Tetrapak, bag-in-box and single serve cans be launched at the LIWF in May.
The wines join an Ehrmanns Fairtrade portfolio that already includes Stellar Organics and Thandi from South Africa and Soluna from Argentina.
