'Green' wine from Chile; Liquid news.

Fancy a drink? Sam Wylie-Harris raises her glass to the week's best buys.

WILD horses and Latino consciousness have helped to make Caliterra winery the sustainable superstar of Chile.

Fifty hungry horses roam the beautiful Caliterra Estate in the Colchagua Valley, where winemaker Sergio Cuadra has set a protocol for eco-friendly production.

The animals graze on the upper slopes in summer, and the vineyards in winter - their insatiable appetite keeps the grass very short, controls forest fires and has put machinery out to pasture.

In true green style, compost is produced on the farm and Caliterra's wine labels are made out of recycled paper.

Less than 40 miles from the Pacific Ocean and enjoying the perfect climate, Caliterra's bug-free vineyards (these healthy grapes are unaffected by phylloxera) and responsible production mean its cellars are stocked with wines of great varietal expression, with minimal impact on the environment.

For classic enjoyment, try Caliterra's Tributo Carmenere Single Vineyard 2007 (pounds 8.99, Taylor's Fine Wine 020 8549 2984 deliver nationwide). That year was a triumph of a harvest, and this satisfying, soft red is a fine example of what the country does best.
