Although i agree wholeheartedly agree with your point, i also feel that it has also become a usual occurrence that the "last batch was better" discussion comes up very very frequently, and so people get fed. If you are drinking PtE or any other beer for that matter, on a very regualr basis, a case can be made, but dont try tell me this years vintage of some rare beer tastes better or worse than last years which you had a pour / bottle of 12 months ago. How much has your palate evolved or changed in the intervening year? How do you remember exactly what it tastes like a year ago. If a batch is infected, that's a no brainer, but very subtle nuances in tasting notes over 12 months...GTFO.. It becomes a boy who cried wolf situation, in that when a particular batch is slightly indeed off, it gets mocked.
