The agreements are exclusive to Berkmann Wine Cellars and the wines†have had no previous distribution in the UK.
Group wine buyer Alex Hunt said: "Hundred-year-old ungrafted vines at Rudeles and Matarredonda give a purity and depth of flavour that few regions in the world can match.
"Furthermore, the emphasis of our new selection is on indigenous varieties, from the well-known such as Tempranillo and Verdejo to the marvellously obscure Albillo, the forgotten white grape of Ribera del Duero.
"We are very excited to present these modern expressions of exceptional terroir."
The wines are available now wholesale to independent retailers, priced from £3.95 for entry level to £21 for the premium, single-vineyard wines.
The y are from Berkmann in London as well as the company's nationwide branches: TM Robertson, Scotland; Pagendam Pratt, Yorkshire; Coad Wine Cellars, Devon; and Berkmann Wine Cellars in Chippenham.
