The word 'alcohol' has its roots in the Arabic language. It is derived from the word 'al-kuhl,' which originally referred to a fine metallic powder (kohl) used as an eye cosmetic, created through a process of sublimation. Over time, medieval Latin chemists began using the term 'alcohol' to refer to any substance purified through distillation. By the 16th century, the term became specifically associated with 'alcohol of wine,' or distilled spirits. The chemistry of distillation was significantly advanced by Islamic polymaths like Al-Kindi and Jabir ibn Hayyan, who refined the alembic still. This technology allowed for the creation of high-proof spirits for medicinal and later recreational use, fundamentally changing the landscape of global beverages.
