The 2007 Insignia (a blend of 88% Cabernet Sauvignon, 8% Merlot and 4% Petit Verdot) looks to be one of the greatest wines yet produced at this historic winery. Beautiful aromas of creme de cassis and flowers jump from the glass of this dense purple-colored effort. Sweet oak is present, but it is pushed to the background by the winersquo;s extravagant wealth of fruit and full-bodied power. This is finesse and flavor authority put into a classic Napa Valley Cabernet with a seamless integration of all its component parts. Already complex and approachable, it should evolve for three decades or more, but who can resist it now? It is a staggering, complex expression of Napa viticulture. Anticipated maturity: nowndash;2030. Another great success for Phelps, the 2007 and 2008 Insignias may be the best back-to-back vintages they have produced since 1995 and 1994. The 2008 has some tannins to resolve whereas the 2007 has already assimilated them.
