Draught Bass has been re-launched into the trade with a quality commitment promise from brand owner Interbrew.
The beer, now being produced by Marston's at Burton-on-Trent, comes with a recipe tweak and promise of a new-style dispense system to help guarantee consistency.
Square fermenters are now used to promote a more fruity aroma instead of the conicles used at the beer's previous home at the nearby Coors Brewery.
Full 100% English hops are also now incorporated instead of an English-American mix and late hops are being added to enhance the taste.
Interbrew has also revealed it is trialling a new "cylinderless" beer engine to address a persisting problem of cask ale being served too warm.
It follows an exhaustive quality audit in conjunction with Cask Marque at 3,000 Bass stockists over the past 18 months.
The transfer of production to Marston's followed the end of the brewing contract between Interbrew and Coors for Draught Bass.
The first commercial brew of Marston's-produced Draught Bass rolled out in mid-February. Interbrew says initial reaction to the brew has been positive, with endorsement received from the Bass Appreciation Society.
Leading beer writer Roger Protz said he is looking forward to trying the beer.
