Distill

Regular 
Concentrates a liquid by removing water from it. This spell is mostly used to make strong alcoholic beverages, but alchemists also employ it for other purposes. Each use of the spell halves the volume of the liquid, doubling its concentration. One casting turns wine into fortified wine, two turns it into brandy, and three leaves a distillate of almost pure alcohol. Distill does not work on living subjects.
