Stones Bitter [is] a pale ale of 3.7% ABV originally brewed by William Stones Ltd, Sheffield, UK at the Cannon brewery in the 1940s. The brand is currently brewed under licence from Interbrew at Coors Burton upon Trent plant UK.
Bitter belongs in the pale ale style grouping, though bitter does have a greater variety of strength, flavour and appearance than mainstream pale ale. A bitter can be dark amber, approaching a stout, or be very golden and delicate like a golden summer ale.
