Blackberries, cherries, raspberries etc., become more intense and complex at first, then level off , eventually decline, and finally disappear. You may find earthy, mushroomy, leathery, tobacco, cigar-box, and even faded violets. The latter could be utterly sublime or it could be disappointing, depending on the wine. A first growth Bordeaux or a Premier Cru Burgundy would be more likely to repay your patience. Telltale color .
Color is a good indicator of the age of a wine.
It can best be observed by tilting the glass over a white background and looking down at the region where wine and glass meet. Think carefully before buying a single bottle to lay down - you will invariably wait too long simply because when it is gone, it's gone. The corollary of that advice is never lay down a case without sampling a bottle when you purchased it and at regular intervals thereafter. You will be surprised at how well you will recall the wine at each stage and you will gain invaluable insight into the process of wine aging. Copyright 1999-2000 Rick Lewis.
