Chile's Bouchon Family Wines is launching a wine made from Pais vines that grow wild among the trees of its Mingre Estate in Maule Valley.
Pais Salvaje is made from decades-old wild vines that grow metres away from the company's cultivated vines of the same variety.
Bouchon claims the vines provide "the purest expression of organic and sustainable viticulture" with a concentration of colour and tannin that is rarely found in Pais.
It is made using ancient winemaking techniques, including the use of the zaranda, a structure made of sticks to destem the grape clusters, and fermentation with natural yeast.
Julio Bouchon Jr, of the fourth generation of the family-owned company, said: "Over the years we have been trying to convey an expression of our terroir and sense of place.
"We have been looking and studying our parcels to find the best vineyard possible and finally we came with the idea of making wine from these as yet untouched grapes.
"It is an honest wine that revives the flavours of Chile's past."
The wine will be available only in limited quantities with a UK rrp of £15 a bottle. Bouchon is represented by Bancroft Wines in the UK.
