Malbec (pronounced mal.bɛk) is a purple grape variety used in making red wine. The grapes tend to have an inky dark color and robust tannins, and are known as one of the six grapes allowed in the blend of red Bordeaux wine. In France, plantations of Malbec are now found primarily in Cahors in South West France, though the grape is now grown worldwide. It has become increasingly celebrated as an Argentine varietal.

A popular but unconfirmed theory claims that Malbec is named after a Hungarian peasant who first spread the grape variety throughout France. French ampelographer and viticulturalist Pierre Galet notes, however, that most evidence suggests that Côt was the variety's original name and that it probably originated in northern Burgundy.

Syrah/Shiraz has a deep ruby-red to purple hue because it's made with red-skinned grapes. When youthful, wines can be inky and opaque. The color is generally darker than Cabernet Sauvignon.

Shiraz wine refers separately to two different well-known wines. Historically, the name refers to the wine produced around the city of Shiraz in Persia/Iran. In the current era, "Shiraz" is an alternative name for the Syrah grape, mostly used in Australia and South Africa. The modern "Shiraz" grape is identical to Syrah and originated in southeast France with no established connection to the city of Shiraz in Persia.
