The move follows the recent introduction of a 1-litre sharing bottle for its Cruzcampo Spanish brand.
A 20-foot inflatable Quilmes bottle is doing a tour of retail sites in the UK to promote the new launch.
Morgenrot claimed sales of the brand were up 80% in the UK during 2010.
It hopes the rugby union World Cup will increase sales in the last half of 2011, especially around Argentina’s first game which is against England on September 10.
Graham Archibald, senior national account manager at Morgenrot, said: “Listings and sales are increasing all the time and this latest roll out will allow us to take advantage of the summer months while setting things up nicely for the rugby World Cup and beyond.”
