It marks the first use of self-cooling technology in the UK beer industry, although several major drinks firms are understood to have looked into self-cooling cans.
It claims the Foster's Cool-Keg holds 35 pints, which it takes to the 'perfect drinking temperature' of 6 deg C within an hour of being activated and keeps it cold for 12 hours.
The CoolKeg will be priced at £49.95, along with a £30 deposit, refunded when the keg is returned. Initially, it will be sold through off-trade retailers in the Brighton area.
Developed in Germany, the technology consists of a non-toxic substance called zeolite, vacuum-encased in the outer cardboard layer, which surrounds a fleece-like water reservoir. When activated, the zeolite absorbs the water which, under vacuum conditions, quickly converts to ice.
John Botia, Foster's brand director at Scottish Courage, said: "The Foster's CoolKeg eliminates any need for complicated dispensing equipment or electricity, and it is set to make cold, draught beer a regular feature at parties and barbeques in Britain for the first time."
The Foster's CoolKeg marked its debut by being served at last week's reunion party for the latest series of reality TV show I'm A Celebrity, Get Me Out of Here!
