From my own little corner of the Earth, it looks like home-brewed beer is growing in appeal—as are micro-brews and wines & ciders made from fruits with a little more natural variation.

So it’s interesting that—just when my crowd is being led by Pied Piper Pollan away from Corporate Consistency-topia into the Land of Natural Individual Variation—those climbing up the Ladder of Disposable Income might drift the opposite direction.

 

I was going to try to make an alluring mathematical comment on this story, but I’m out of steam. Here are the mathematical concepts involved in this story:

  • "direction" — implies ∃ beer space, ∋ beer vectors
  • this is a perceptual space — what are the dimensions? Is it linear?
  • how would you mathematically model variable-versus-consistent beer tastes?

    Maybe as a contour plot / heatmap of confidence intervals? Or a Schwartz distribution?

    I wouldn’t assume that the variation is Gaussian. Whatever the taste / smell space looks like, a lot of the variation in homebrewing is due to creativity (discontinuous leaps to elsewhere in the space) — not just to production “errors” (which might in fact be normal).
