Viu Manent is probably the best malbec producer in Chile. While Argentina has been usually identified with malbec, the best reds from Chile are typically cabernet-based. However, in the past few years some producers have been increasingly experimenting with malbec. Viu Manent is probably at the forefront of that group.
This is their second wine, but by no means a slouch. 85% malbec, 15% cabernet sauvignon with grapes harvested from 40+ year old vines in Colchagua Valley. Amazing color, a vivid, bright purple. Soft aroma of red berries and tobacco. Medium/full body, 14% abv. I got red plums, tobacco leaves, a touch of cedar and pepper. Very moderately tannic, not an ager. Medium finish. Aged for 14 months in French oak. Very well done, classy malbec.
They also make a highly aromatic top of the line malbec called "Viu I". Some time ago I posted a TN on that wine from a tasting done in Chile - I found it to be sensational.
