The beer one had a good run, lets see how this does. Best: so far, probably aspalls. However, that is from a lamentably small sample, and I am sure I shall find a superior one soon. Research is ongoing. Worst: probably one of those ones that come in 2l plastic bottles. I've never found one of those that is even drinkable, to give some idea of how terrible they are I went camping with a few friends and a couple of bottles a year or two back (when I shouldn't really have anything alcoholic, and so were fairly tolerant of bad stuff - beggars can't be choosers and all that) and we ended up throwing it off a cliff. It really was that bad.
