The beverage industry (also known as the drink industry) produces beverages, often as ready to drink products. Beverage production can vary greatly depending on the product being made. Products may be canned or bottled (plastic or glass), hot-fill or cold-fill, alcoholic or non-alcoholic, and natural or conventional. Quality control is a critical factor in this highly-competitive industry where it's also important for companies to stay ahead of trends and consumer tastes.
