From the winery:
Grown in Napa Valley's premier vineyards, our Merryvale Varietal and Single Vineyard wines are limited production, expressive wines. Hand picked, and carefully sorted, these wines are handcrafted in small lots and aged in the finest French oak. - See more at: http://www.merryvale.com/index.cfm?fuseaction=wines.main#sthash.UpLwQxMt.dpuf
Napanook is a blend of bordeaux varietals specifically selected from the estate vineyard for their lively fruit and bold character. Napanook wines are youthful and exuberant, meant to be enjoyed regularly when a more casual wine is called for.
The 2009 vintage is composed of 87% Cabernet Sauvignon, 5% Cabernet Franc, and 8% Petit Verdot. This wine is created to be consumed young, and enjoyed with food, but will also age well for more than a decade. Christian Moueix recommends decanting young wines before serving to allow them to reach their full potential.
