The Estate Cabernet is one of California's finest.  It hails from vineyards behind the property just outside of Calistoga where there is plenty of volcanic soils to offer great drainage and complexity.  The 1999 vintage of Montelena Estate is highly admired by Robert Parker and he feels it will drink beautifully till 2030.  This big, concentrated wine comes from very low yeilds, somewhere below 2 tons per acre.
