You won't find many of them in good shape, was nearly 20 years ago!White Shield got ruined when Worthingtons got taken over by Coors a few years back.
The pre Coors bottles are one of the best bottled ales you`ll ever taste and are highly sought after as a result.
It was one of the only beers that I can think of that had sediment in the bottom like home brew !
When your choices in a supermarket are the likes of Doom Bar, Tribute and the like its still a good shout I reckon, its as good as Landlord in a bottle.
