The job duties of a distiller involve working in a distillery that produces spirits, such as whiskey, rum, gin, vodka, or other forms of liquor. The distillation process that you oversee in this career may vary slightly depending on the type of alcohol that you create. Generally, your responsibilities involve gathering water and raw materials and putting them through a fermentation process. In many cases, you may oversee blending and bottling. In larger distilleries, a master distiller is in charge of a team of professionals, each of whom carries out one step in the production process.
