In reply to O Mighty Tim:
Tim (+ others)
Lets get a few facts correct
InBev (the owners of the Dr Bass name) have moved Dr Bass production from Coors Burton Brewers to the Marstons Burton Brewery. Marstons is owned by Wolverhampton & Dudley
(InBev was formed by Interbrew and AmBev - both Global Beer producers)
Dr Bass has not been made with the Burton Union system for the last 15-20 Years.
Marstons Pedigree is the last beer to be produced using the union system (maybe this is where confusion may be coming in)
Coors no longer produce cask ales in Burton, but have contract brewing agreements with other smaller regional breweries aroung the UK.
Coors has withdrawn 1744 cask due to low demand.
Worthington White Shield is still available (currently in Morrisons/seafeway, Sainsburys, Tesco and Coop to name a few) and is Brewed and packaged by the Coors Visitor Centre in its own Micro brewery
The Coors Burton Brewery will certainly NOT be closing due to the volume switch of Dr Bass. Dr Bass accounted for only approx 1.5% of total volume output.
About 78% of the UK beer volume is produced by the biggest 4 Brewers (Coors/Scotco/IUK/Carlsberg UK)
Hope this helps to clear up any confusion
