A thief is a simple but essential tool used in distilleries and wineries to sample liquid from barrels or tanks without disturbing the entire batch. It's basically a long tube or pipette that allows workers to "steal" a small amount of the product to check its quality, flavor, or progress during aging. The name comes from its action of "stealing" a sample. Other common names for this tool include wine thief, whiskey thief, or barrel thief. This tool is crucial for quality control and monitoring the aging process of spirits and wines.
