In the world of Scotch there are very few distilleries that deliver a "sure thing" year after year - a product whose quality doesn't diminish much, if at all, and sometimes exceeds itself. Many of the vaunted and much-hyped distilleries have faded - Glendronach, after their old stocks were expended; Ardbeg seems to be using tired casks, especially for the Uigeadail; everyone agrees Macallan and Balvenie and such are much diminished from yesteryear. It's such a common talking point that it's more or less a cliche.
Yet I think it's a pretty popular opinion that Bruichladdich has kept things marvelously consistent.
