The job of a taste tester is to provide sensory feedback on food and beverages. Before food companies manufacture a product, they test out recipes and, as a taste tester, your duties are to provide input to the food technicians or chefs who survey you on a number of qualities about the product, such as taste, smell, and texture. Other responsibilities may include providing quality control and assurance to ensure that product taste and other qualities remain consistent within a batch and among batches.
