Fine Wines especially from Bordeaux typically need 7yrs to get to that starting point of optimum drinking. Once a wine gets to the 10 year age, this is for when the drinkers start popping those corks and drinking the top wines from the world.
As these wines are limited in production the moment the world starts to drink the numbers left in the world start to fall, pushing the prices higher year by year. So far the big demand is for Chateau Latour 2005. For many this has the signs of a future classic and has the big characteristics you would look for from a top a top teir fine wine
96 / 100 -
Only 44% of the production made it into the dense ruby/purple-hued 2005 Latour, a powerful, backward, 12,000-case blend of 87% Cabernet Sauvignon and 13% Petit Verdot and Merlot. As I wrote last year, this classic effort is built for the ages, and is largely destined to be drunk by our offspring rather than anyone over the age of 50 today. Complex aromas of crushed rocks, graphite, black cherries, creme de cassis, new saddle leather, and dried mushrooms are still tightly wound. The wine is full-bodied and powerful with exceptionally high tannin combined with zesty acidity, and laser-like focus. It will require 15 or more years of cellaring. I still prefer the 2003, but administrator Frederic Engerer says this “is more Latour.” Anticipated maturity: 2020-2060.Latour is always the most difficult Medoc first-growth to find, largely because the vineyard and production are much smaller than its’ peers and because of the severe selection routinely done by owner Francois Pinault and administrator Frederic Engerer.
