The keg has been on trial in Sainsbury's, Threshers and Makro since last summer, and Heineken said it sold well, especially over Christmas. It will now roll out to Tesco, Morrisons, Waitrose, Somerfield, Booker, Nisa-Today's, Costcutter, Spar and others.
Heineken is backing the roll-out with promotions, bespoke and generic POS items including floor-ready display units, and a spring burst of advertising to drive awareness.
Customer marketing controller Chris Duffy said: "With the final rounds of the Heineken Cup coming up in April and May and, providing we have a good summer this year, the onset of the barbecue season picking up after the Heineken Cup final, we wanted to extend distribution of DraughtKeg now so that all
our customers will have the opportunity to stock and benefit from the 5-litre pack for these key sales periods."
DraughtKeg retails at £13.79-£13.99, which means it costs £2.80 per litre - 63 per cent more than the average £1.72 for lager, according to Heineken.
