Wine Advocate-Parker :
The harvest at Petrus took place between September 27 and October 12, and the 2010 finished at 14.1% natural alcohol, which is slightly lower than the 2009's 14.5%. The 2010 reminds me somewhat of the pre-1975 vintages of Petrus, a monster-in-the-making, with loads of mulberry, coffee, licorice and black cherry notes with an overlay of enormous amounts of glycerin and depth. Stunningly rich, full-bodied and more tannic and classic than the 2009, this is an awesome Petrus, but probably needs to be forgotten for 8-10 years. It should last at least another 50 or more.
