The Bugey, halfway between Lyons and Geneva, is one of the tiniest and most obscure wine areas in France. Although the altitude is modest, the terrain is very mountainous, the roads are steep and winding as in the Alps, and the villages are built for cold winters – the houses made of gray/white limestones all bunched together on narrow streets The vineyards are hard to detect, little patches here and there on steep slopes looking southeast or southwest, lost in the midst of fields with grazing cows, and dense forests. The total Bugey acreage in vineyards is 170 hectares. The varietals are many, borrowed from all the surrounding areas: Gamay, Poulsard (a grape from Northern Jura), Roussette, Mondeuse (both from Savoie) and Chardonnay. Many still wines are produced, but the region's star wine is the Cerdon Méthode Ancestrale, a semi-dry, pink bubbly made by spontaneous, but incomplete, fermentation.
