D&F Portuguese Wines was founded in 1977 and has been handling high-volume brands such as Ramada since then.
Now managing director Fausto Ferraz is set to unveil a more upmarket range targeted at independendents and the on-trade.
He said: I want to showcase the range and quality of premium and fine wines which Portugal now produces countrywide and I believe that D&F has the potential to be a leader in this category.
The range is made up of 25 wines made from native varieties grown in well-known and up-and-coming parts of Portugal.
It includes Quinta do Regueiro Blend, a non-vintage Alvarinho from award-winning winemaker Paulo Rodrigues, and Conde de Oeiras Carcavelos from a tiny, near-extinct fortified wine DOC.
The company will showcase its range at a tasting on London on April 15, where there will also be masterclasses by Wine Detective Sarah Ahmed and master sommelier Joćo Pires.
