Cubism theory through the writings of Albert Gleizes. However, the linking of basic geometric forms with inherent beauty and ease of industrial application—which had been prefigured by Marcel Duchamp from 1914—was left to the founders of Purism, Amédée Ozenfant and Charles-Édouard Jeanneret (better known as Le Corbusier,) who exhibited paintings together in Paris and published "Après le cubisme" in 1918. Le Corbusier's ambition had been to translate the properties of his own style of Cubism to architecture. Between 1918 and 1922, Le Corbusier concentrated his efforts on Purist theory and painting. In 1922, Le Corbusier and his cousin Jeanneret opened a
Vin gris technique to improve Pinot noir. Removing some clear juice increases the concentration of colour and flavour compounds from the skins in the remaining juice intended for making red wine; the resulting rosé is known as a "saignée" (bled). Another grape used to produce Vin Gris is Gamay, particularly in Lorraine, where the Côtes de Toul zone produces a light and delighting Vin Gris. The vinification is the same as with Pinot Noir (short contact of the white juice with the red skins during the pressing), but the fruity flavour of the Gamay very much changes the taste of the wine.
