Jean-Yves Péron is a trained enologist who created his own domain in January 2004. He began by buying micro-parcels in Conflans, a medieval site in Albertville. Nowadays, his indigenous grape varieties (Mondeuse for the red wines and Jacquère for the whites) grow on two hectares of hillsides (between 400 and 600 metres of altitude). In addition to these, he also grows other varieties such as Persan, Altesse and local Roussanne. The vines are between 30 and 120 years old. He uses neither fertilizer nor any synthetic weedkillers, opting instead for natural treatments (nettle for example) and tilling the soil. His work in the winery is remarkably non-interventionist, or ‘natural' even; after manual harvests, the grapes undergo carbonic maceration and are punched down once or twice a day in order to extract a good dose of colour. Some of his wines have no sulfites added to them.
