These are all the same grape - Mourvedre, Monastrell in its native Spain and Mataro here in Australia and in California. It is a black-skinned grape that has been grown in vineyards around the western Mediterranean for centuries. Thought to have originated in Spain, it is now grown extensively throughout the Iberian Peninsula, southern France, California and South Australia.
Mourvedre grows best in warm, dry climates and has small, thick-skinned berries – the textbook combination for making wines with intense colour and high tannins levels. In fact, it is the variety's mouth-drying tannins that earned it the French nickname Etrangle-Chien (the dog strangler). Teusner indeed has a wine called 'The Dog Strangler'.
