Newcastle keg beer is offered in 5 liter pressurized kegs of BeerTender format. Beertender is the Heineken patented mini kegs, and therefore is the format in which all Heineken group beers are offered.
As stated in past articles, being a pressurized keg means that a specific connector is required for operating the keg. All Beertender kegs are sold with a plastic tap that is enough to serve the beer although is not the same experience than serving the beer using your own beer tap.
If you own a beer tap and want to use your Newcastle keg with it you must ensure that your beer tap is compatible with Beertender kegs.
