Lovers of Château Latour used to buying the famed first-growth estate's newest vintage during the en primeur season may want to hurry. The 2011 vintage will be the last en primeur offering, after the estate announced just before the weekend that it would no longer use the en primeur system to sell its most recent vintage. Beginning with the 2012 vintage, Latour will not announce a price in the following spring along with the rest of Bordeaux, as it has historically done. Instead, it will only make the wine available for sale until after it is bottled and when the estate feels it is ready to drink.

Having thought this out, I'm in favor of it! It'll annoy the middlemen, which may be a plus or minus depending on your situation. But in the end it's actually a big step forward in quality control.
