"RichD" asked the collective wisdom of the group.............
Ah, the question of the ages :-)
Perhaps, a better phraseology would be "How does one determine if a wine is
*age-worthy*.
I am not suggesting that this change of words will bring you closer to a
definitive answer to your questions, but it does give focus as to why one
should cellar any particular wine.
Many might argue that a wine will become "better" with aging.
At the risk of sounding flippant, *each and every* bottle of wine can be
stored in an appropriate storage facility for a few months or a few years -
however, usually little can be gained - most will certainly not be "better"
for their time in custody.
If a wine does not possess those elements which make it "age-worthy",
pedigree; structure; fine fruit/sugar/acidity/tannin balance, these same
wines, though capable of enduring, won’t actually change.
If red, they may get smoother, shedding whatever tannins they had - if
white, they will probably oxidise into oblivion.
But nowhere along the journey from youth to old age will they have become
dramatically, dimensionally different from what they were when first made.
And this is the key as to which wines to cellar - which wines, through
careful cellaring over many years will *transform* into a thing of elegance
and grace - a veritable sensual symphony? And here I must declare that I
have no absolute answers.
You see, my taste is probably totally different to yours - I am on safe
ground in making this statement, because my own taste differs from most of
my contemporaries.
So, firstly, your own likes and dislikes must be your first determinate.
Next, there are some wines whose aging journey may be likened to the
metamorphosis from ugly caterpillar to beautiful butterfly, such is the
transformation.
Varieties such as Riesling, Semillon, Chardonnay (particularly grand cru
Chablis) may undergo a wonderful transformation with 10-15-20 years of age.
Age-worthy reds include classified growth Bordeaux (and a few Californian
Bordeaux styled examples); some Burgundy and Rhone reds. Traditional Barolo
is very tannic when young but ages well.
A wine chemist may be able to identify and quantify the various elements
which will contribute to a wine being age-worthy: acidity and pH and alcohol
content; polymeric combinations of anthocyanins and tannins (although, as
previously indicated, white wines pursue a very different chemical logic
from what happens in red wines) - but many more factors come into play:
optimum cellaring; screwcap or cork closures (we are still learning)
Can we foresee how long a wine will live, or at least which ones will live
for a long time? Probably.
Can we prophesy what the survivors will taste and smell like? Probably not -
not until the bottle is opened will this question be answered.
I guess my own short answer to your question can be summed up in one word
"Pedigree" - and the undying belief that one cannot make a silk purse out
of a sows ear.
