Source is a certified organic Melon Blanc, the grape variety behind Muscadet, grown on the granite and shallow stony soils of Château-Thébaud, one of the most respected corners of the Nantes vineyard. The hand-harvested fruit ferments naturally with wild yeasts at 16°C, then rests for seven months on its fermentation lees in stainless steel, without malolactic fermentation and with only light filtration. That slow aging on lees builds texture and preserves the variety's delicate aromatics. The finished wine is dry, fragrant, and has a gentle savoury bitterness on the finish.
