Bugey, a tiny region at the foothills of the Jura Mountains produces world-class wine that France tends to keep for themselves to drink in lieu of exporting. Most cru Montagnieu sparkling is Chardonnay-dominant; Peillot emphasizes local varieties Altesse & Mondeuse. Made by méthode champenoise; there is a subtle biscuit quality with orange, lemon curd, green apple and pear.
