I know I am very conservative in my choices of beer, but I must admit I have never heard of a lot of ales you mention. Where do you get them from?
Sierra Nevada can be found in most supermarkets these days.
They were all on tap in Slater's and the Dog & Doublet.
There are plenty of online retailers as well, if you look at Honest Brew, Brewdog, Eebria etc there are absolutely loads to choose from. Bit on the expensive side but well worth it.
Tesco or Asda are a good start too - not too many of the really obscure beers, but they generally have a good selection of craft ales (including my favourite dead pony club).
