Groth is one of those wineries that used to get a lot of buzz.  Now, they are somewhat yesterday's news although the truth is, Groth is still making excellent California Cabernet and deserves to still be in the conversation.  This one was from Magnum.  Purple in color, ruby at the rim.  The nose is dusty with nice cassis fruit.  Some baking spice as well.  On the palate, this is drinking well.  Probably not at peak yet.  Complex layers of cassis and spice with some dry earth.  Medium tannins.  There is a strong backbone of acidity here that is helped by fatty foods.  Nice finish.  At around $50 a bottle, this is fairly priced for a Napa.  Easily has a decade more of life.
