This wine is made from grapes grown on a terroir near the village of Le Castellet. The vineyard sits high up on the hillside, on average 170m above sea level, and has relatively homogenous soil comprised of chalk and clay on top of 100 million year old rock. The Mourvedre vines flourish on this terroir producing excellent wines that are powerful, tannic and fruity. La Tourtine comprises 70–80% Mourvedre depending on the year. Frequently windswept by the mistral, this vineyard is particularly well exposed, resulting in a wine with long ageing potential that retains its red berry and spice aromas even after 10 to 15 years.
