Robert Parker's Wine Advocate : The dark plum/ruby-tinged 2004 Petrus possesses high acidity as well as copious amounts of sweet cherries and black currants intermixed with hints of cola, earth, and truffles. Deep, medium-bodied, concentrated, ripe flavors are excruciatingly firm and tannic. This backward, structured, muscular Pomerol (…) it possesses the potential to be the longest lived wine of the vintage, lasting 30-40 years.
