Draft beer (or draught) is beer served directly from a keg or cask rather than a bottle or can, usually dispensed through a tap system.

​Bottled beer, popularized in the 19th century, remains a premier packaging choice for its ability to preserve flavor without the often-metallic or plastic liner taint sometimes found in cans.

Canned beer, which revolutionized the industry in 1935, offers superior protection against light and oxygen, enhancing freshness and preventing "skunky" flavors.

Non-alcoholic (NA) beer contains little to no alcohol—typically under 0.5% ABV—and is produced by restricting fermentation or removing alcohol via vacuum distillation or reverse osmosis.
