Alcohol

Alcohol results from the action of yeast on sugar. The yeast converts sugar into ethanol; which, as it was inhospitable to bacteria, would retard spoilage. It has been drunk, used, seen, and even occasionally manufactured by the Doctor, companions, and others.

Adventurer archaeologist Bernice Summerfield (who travelled with the Doctor for some time) greatly appreciated alcoholic beverages.
