Oeil de Perdrix () is a rosé wine produced in Switzerland. The history of the wine style dates back to the Middle Ages in the Champagne region of France and from there spread to the Canton of Neuchâtel in Switzerland where it would become a popular dry rosé made from pinot noir. The name œil de perdrix means "partridge's eye" in French, a reference to the pale pink colour of the eye of a partridge in death throes. Until about a century ago, it was common for vineyards to have the red and white grapes unseparated unlike today where each vineyard has a unique grape. This gave white wine, red wine, and what was called grey wine because the wine was neither white nor red. It is also an old name for very pale rosé wine made not by the saignée method, but by "pressurage direct", in which the juice of red grapes is drawn off and fermented with very little contact with the skins. With the modernization of viticulture and separation of grapes, the term Oeil de Perdrix disappeared in France, but remained in the Canton of Neuchâtel in Switzerland. The Canton of Neuchâtel would export Oeil de Perdrix primarily to the German-speaking cantons of Switzerland, but also to other cantons, namely to the cantons of Geneva, Vaud, and Valais. After the Second World War, the latter decided to start producing their own Oeil de Perdrix. When the policy for wine of controlled origin (AOC) in Switzerland began, the Canton of Neuchâtel claimed the sole Oeil de Perdrix AOC, but it was refused; the cantons of Geneva, Vaud, Valais, and Neuchâtel all have the Oeil de Perdrix AOC today. The early origins of the American wine White Zinfandel can be traced to a California winemaker's attempt at making an Oeil de Perdrix–style wine. History The Oeil de Perdrix style of wine is believed to have originated in the Middle Ages in Champagne region of France, prior to that region's development of the sparkling wine style that would take its name. During this period the Champenois were in competition with the Burgundy wine region for the favor of the Royal court and the lucrative Paris market. Red wine was particularly popular during this period and the northern location of the Champagne region had difficulties competing with the more fuller bodied wines of Burgundy.
