Shelf life of a keg beer?

Type of beer:

* Lagers: Generally have a shelf life of 3-6 months after the keg is tapped.

* Ales: Have a shorter shelf life of 2-4 months after tapping.

* IPAs: Typically have a shelf life of 2-3 months after tapping.

Storage conditions:

* Temperature: Storing kegs in a cool, dark place (ideally between 35-40°F) can extend shelf life.

* Exposure to light: Light can degrade beer, so keep kegs away from direct sunlight.

* CO2 pressure: Maintaining proper CO2 pressure in the keg is crucial.

Other factors:

* Type of keg: Stainless steel kegs generally preserve beer better than plastic kegs.

* Cleaning and sanitizing: Proper cleaning and sanitizing of the keg are essential.

Signs of spoiled beer:

* Off-flavors: Sour, skunky, or metallic taste.

* Cloudy appearance: Beer should be clear, not cloudy or hazy.

* Sediment at the bottom: This indicates yeast or other particles have settled.

Note: These are general guidelines. The best way to determine if a keg beer is still good is to taste it and see if it has any off-flavors.

To prolong the shelf life of a keg beer:

* Store it in a cool, dark place.

* Use it within the recommended timeframe.

* Keep the CO2 pressure at the correct level.

* Clean and sanitize the keg properly.
