I'm always amazed that these products can be so accurately locked to an exact flavour for years, regardless of the inputs, which, being plant or animal matter, can vary a lot naturally between batches and between years.

Not only whisky, even things like branded fruit juice, McDonald's burger meat and salad, Nutella and branded chocolate, coffee, to name just a few, seem almost preternaturally consistent.
