Interbrew UK has signed a supply agreement with Six Continents Retail - the largest managed house operator in the UK - which will see draught Stella Artois introduced into the company's outlets nationwide.  Under the new agreement, draught Stella Artois will be stocked in selected retail brands across Six Continents Retail, with roll out commencing in December. The new agreement was negotiated following the successful trial of draught Stella Artois in 25 Six Continents Retail outlets during the summer.
