Special technique for making red wine in order to achieve intensive extraction of the colouring agents and tannins from the grape skins. The process was developed in Algeria in the early 1960s under the name Ducellier system. Autovinification is derived from the self-renewing process. The grapes, which are generally destemmed and ground, are pumped into a specially equipped stainless steel tank. During mash fermentation, a strong carbon dioxide pressure builds up, which channels the fermenting grape must through a valve into an open basin on top of the tank. At the same time, this pressure forces water through a second valve into a smaller container.
