What it is

The production of concentrated ethanol by distilling wine with a cooled still, described at Salerno in the 12th century. The 'burning water' is born, later called 'water of life'.

al-Kindi (9th century) describes the distillation of wine for perfumes; the Arabs obtained alcohol but did not set it apart as a drink, owing to religious prohibition. Transmission ran from the Islamic world to Salerno.

What it led to

  • spirits, liqueurs and European distilleries of the 14th–15th centuries
  • a solvent for pharmacy, perfumery and tinctures
  • the concept of 'quintessence' and the chemistry of spirits (John of Rupescissa)
