Not including premiums (OP etc), and must be cask conditioned in t’pub
1. Theakstons XB
2. TT Landlord
3. Black Sheep
4. John Smiths cask
5. Tetley’s cask Original
Am I right?
Contradicting your own thread title with your OP.
Landlord is indeed a lovely drop but is a Pale ale not a bitter.
Timothy Taylor’s bitter is Boltmaker
That is a fine pint but not a match to Sheep Best Bitter or Theakston’s Best Bitter.
Black Sheep Special is great too with a higher ABV similar to Theakston XB.
Theakston OP (lunatic broth) and Black Sheep’s superior Riggwelter are both just short of 6% ABV darker heavier ales, not seasonable and I don’t like either.
There are Blondes and Citrus IPA’s offering pleasant variety, but my personal ranking of OP's best Yorkshire Bitters would be:
1. Black Sheep Best
2. Theakston Best
3. Timothy Taylor Boltmaker
Its a while since I've come across Tetley Cask or John Smith Cask.
At the end of the day, its what you like that matters, not the technicalities.
Wainwright was canny despite being Cumbrian, but not so much now its brewed down in the West Midlands.
