Malbec is a French variety, traditionally used in Bordeaux blends, and in Cahors, but has more recently found great popularity in Argentina. It works well in Hawke's Bay, but is a somewhat fickle variety in the vineyard - prone to highly variable fruit-set - which gave a small crop in 2017.
Hand-plunged with a relatively warm ferment, then given a good long soak on skins to add a bit of spice and complexity to the primary fruit. Pressed off into French oak and matured therein for 15 months.
The Argentinians drink it with steak; that's probably at least partially because they seem to spend most of their time eating steak, but it's a pretty good match regardless.
