Champagne
wiktionary
Borrowed from French champagne(“sparkling wine from the Champagne region”), from Champagne(“region and former province of France”), from Late Latin campānia (in full Campānia Rēmēnsis), from campāneus(“of or pertaining to the fields”), from Latin campus(“level ground; field, plain”), from Proto-Indo-European *kh₂emp-(“to bend, curve”). The English word is a doublet of campagna(“flat stretch of countryside”)(dated) and campaign.
etymonline
champagne (n.)
effervescent wine, 1660s, from French, short for vin de Champagne "wine made in Champagne," the former province in northeast France, literally "open country" (see campaign (n.)). Originally any wine from this region (especially from the vinyards south of Reims); the sense focused on the "sparkling" wines made there (the effervescence is artificially produced), then by late 18c. expanded to effervescent wines made anywhere.
