Dominique Piron controls approximately 40 hectares of vines in the villages of Regni, Brouilly, Morgon and other surrounding areas. Some of the vineyards are owned by his family, and some are rented. All are controlled by Piron from vine to wine, so that even though some of his wines are technically negociant wines, he is responsible for every aspect from the vineyard care to the marketing of the finished wine. Coq Leon is unusual in that it has blended in 5% Gamaret, a varietal created in the 1990s by crossing Gamay with Reichensteiner; the grape never caught fire, but there are still plots of it growing throughout the region, one of which belongs to Julien Revillon, who has recently taken over Pirons operation. The resulting wine is plump, delicious, without artifice, and very food-friendly.
