Page "Jupiter (mythology)" Paragraph 57

Other scholars assert that there was no Liber ( other than a god of wine ) within historical memory.

O. de Cazanove argues that the domain of the sovereign god Jupiter was that of sacred, sacrificial wine ( vinum inferium ), while that of Liber and Libera was confined to secular wine ( vinum spurcum ); these two types were obtained through differing fermentation processes.

The offer of wine to Liber was made possible by naming the mustum ( grape juice ) stored in amphoras sacrima.
