Ready-to-drink (RTD) beverages are pre-mixed alcoholic drinks that come conveniently packaged in bottles, cans, or cartons and are designed for immediate consumption without the need for mixing or additional ingredients. Popular among consumers seeking convenience, portability, and consistency, RTD's span a wide range of styles, including spirit-based cocktails (like premixed gin and tonic or rum and cola), wine-based coolers, hard seltzers, and alcoholic iced teas or lemonades.

They typically have a lower to moderate alcohol content (around 4–8% ABV), making them easy to enjoy in casual settings such as parties, barbecues, or outdoor events. RTD's often feature fruity, sweet, or refreshing flavours, and their growing popularity is driven by trends in low-effort, on-the-go drinking, as well as the demand for lower-calorie and lower-alcohol alternatives to traditional mixed drinks.
