If there’s a flavor for whom appreciation only arrives with age, that flavor would be bitterness.
That’s not to say that most people become bitter with age; I would certainly hope not. Rather, I’m speaking about the flavor profile – astringent, sharp, piercing…shocking, even. And yet, so many of life’s more adult (and particularly liquid) pleasures – a well-brewed cup of coffee, the tannic finish on a glass of feisty red, the quinine snap of tonic water – are built if not focused on this unusual sensation.
