The source of the flavours is fresh wild gentian root from the Auvergne, and fresh cultivated gentian root from Normandy - half of each. The wild roots take 20 to 30 years to be ready to harvest, while the cultivated variety takes a mere 9 to 13 years. The wild roots are harvested manually with an implement known as la fourche du diable - the devil\'s fork. The gentler terrain of the cultivated roots can be mechanically harvested, although selection is still entirely manual. The roots are macerated in neutral alcohol for around a year before being pressed to extract the flavour. The bouquet is enhanced by the addition of a distillate of angelica and other herbs. Over time the strength of Suze sold in France has declined to 15%, with a consequent reduction in the intensity of the flavours. Suze Saveur d\'Autrefois (taste of the old days) is a return to the original style.
