When comparing any specific brew on tap at different pubs you add the variable of the pubs line maintenance. Do they clean them regularly or not.
As for the inconsistency in bottled brew, a factor can be handling. Ive seen pallets of beer cartons, JS products included, sitting outside the store (coughdammurphyscough) in the sun on a 40 day after its been offloaded from an open truck. Cant do it much good. That said, Ive noticed inconsistency between bottles from the same 6 of JS IPA and Porter. Thought at first it may have been my taster, but Im thinking there may be an issue with mass-production.
