The fermentation process started within six to twelve hours after pressing, and the must was usually left in the collection vat for a few days to allow the initial, "tumultuous" stage of fermentation to pass. The wine makers soon transferred it either into large earthenware jars, which were then sealed, or, if the wine were to be transported elsewhere, into wineskins (that is, partially tanned goat-skins, sewn up where the legs and tail had protruded but leaving the opening at the neck). After six weeks, fermentation was complete, and the wine was filtered into larger containers and either sold for consumption or stored in a cellar or cistern, lasting for three to four years. Even after a year of aging, the vintage was still called "new wine," and more aged wines were preferred.
