A Column Still, also known as a Continuous Still or Patent Still, is a type of equipment used in modern distilleries to make spirits like vodka, gin, and some types of whiskey. Unlike traditional pot stills, it can run continuously without stopping, making it more efficient for large-scale production. Think of it like an assembly line for making spirits, compared to the batch-by-batch process of older methods. It's a tall column with multiple levels that helps separate and purify alcohol more efficiently than traditional methods. When this term appears in resumes, it usually indicates experience with industrial-scale spirits production and modern distilling technology.
