Biodynamic. This wine is named in honour of the 11th century Persian poet, philosopher, booze-hound and mathematician, Omar Khayyam. This vibrant, supple bottling comes entirely from a single highland plot which is above the house at the top of the Saint Marcel d'Ardèche plateau. The site is littered with galets roulés and was planted between 1960 and 1980—mostly to Grenache, with 10% Syrah and 15% Mourvèdre. Some 30% of the fruit was aged in large casks on lees, bringing a seductive, supple and layered texture to the bright, cleansing structure.
