I prefer the VP to the VC. In color, aroma and taste. But that's a recipe and process thing.
As far as color change affecting taste, I believe the answer is that it doesn't. It's just chlorophyll breakdown. A heavily colored verte, however, will have some taste issues associate with the extra herbs used. But those are taken into account with the recipe, and again, won't change with color shift.
I don't know what chlorophyll tastes or smells like... but the turning of absinthe, or rather, the
appearance of senescence in an absinthe that we associate with the
feuille morte is usually conditioned on a number of things that are all related in a complex way to what you'll eventually taste and perceive in the glass. Where the color is concerned, the final character - especially the bouquet - is dependent and augmented according to, among many things, the strength the absinthe is delivered/bottled at; perhaps, even, the means of storage and the characteristics of the storage vessel... if not inert; before this, the degree chosen for vieillissement/aging; before that, the proportion and preparation of herbs used in the coloring; leading into that, the method assumed and the application of heat in coloring...
So when light and oxidative effects play themselves out, conditions will have to be right for an
«absinthe riche» (60-72°) to begin to break down - and I'd be lying if I said I know all the reasons why - but, again, we are all aware they depend greatly on light and oxygen. And just as conditions allow for the instability of chlorophyll to be apparent, the same conditions allow for positive or negative changes to occur that you'll taste, detect and appreciate or reject. So with respect to color, I'm personally compelled to believe there's this associativity that shouldn't be ignored.
Something I'm curious about, I wonder if producers who customarily bottle at 60° now, which would seem in a most practical sense to be almost obligatory (but which I've bitched about numerous times in the past... Sorry, PV), will tend towards highers strengths as they establish themselves, and whether, in kind, we'll see a difference, within brand, in the color put before the customer.
