What does distil mean?
Distil means to purify a liquid through heating and condensation, separating it from unwanted substances, and by extension to extract or concentrate the essential elements of anything. The literal sense applies in chemistry and industry: water, alcohol, and petroleum products are all commonly distilled. The figurative sense is equally widespread in educated usage — a speaker might distil a long report into three key points, or a novelist might distil a lifetime of observation into a single scene. The word implies careful refinement and the removal of everything non-essential, giving it a positive connotation of clarity and concentration. In British English it is spelled with one 'l'; American English uses 'distill'. Derived forms include distillation, distiller, and distillate, all central to chemistry, brewing, and spirits production.
To purify a liquid by heating it until it vaporizes and then condensing the vapour back into liquid, separating it from impurities.

Every drop of whisky you've ever tasted has passed through the same basic process alchemists used over a thousand years ago — distillation was once believed to capture the very 'spirit' of a substance.
