Beer is also considering as a perishable foodstuff. As it will deteriorates as a result of the action of bacteria, light, and air. However, unlike other food products, packaged beer is not legally mandated to carry a "sell by" date.

Beer should be always placed in a temperature-controlled or refrigerated environment to prevent the beer from deteriorating. Most beer is packed in bottles, cans, widgets and growlers.

Clear versus colored glass bottles

The reason why most beer bottles are amber or green, it is because the full spectrum of daylight can have undesirable effects on a beer over a period of time. The ultraviolet portion of the spectrum is very harmful; promoting chemical reactions that produce "off flavors" that will take the edge off the freshness of a beer. Dark glass greatly inhibits this undesired effect, whereas clear glass leaves the beer very vulnerable to be "light struck."

Nitrogen capsules ("widgets")
The widget is a small plastic capsule containing pressurized nitrogen gas that rushes out of a pinhole when the can is opened and the internal pressure is lowered. Widgets have now found their way into bottles as well as cans, although it does not necessarily has the same levels of critical acclaim.

Aluminum cans
Aluminum cans are more popular at the general market. Packaging in aluminum cans does necessarily imply pasteurization. Although cans do not fit the image of the craft-brewed product, there is no technical reason why high-quality beer cannot be sold in cans, and, in fact, a number of craft brewers are launching canned products. The reason why craft brewers used cans instead of bottles is due to the high capital cost of the pasteurization and packing equipment required.

Growlers
A growler is a plastic or glass container used for selling fresh draft beer straight from the tap. Beer sold in this format, generally from a brewpub, must be refrigerated and then consumed within a day or two.
