The 2010 Cabernet Sauvignon Beckstoffer To Kalon Vineyard Old Sparky, made from clone 4, 6 and 337, displays a dense opaque purple color as well as an incredible nose of graphite, cedarwood, incense, licorice, Christmas fruitcake, vanillin and abundant blackberry and black currant liqueur. Gorgeously rich and textured with a nearly endless finish, this super intense, full throttle wine needs 5-7 years of bottle age and should drink well over the following 25-30 years. It was aged 20 months in 100% new oak barrels.- Robert M. Parker, Jr. (10/2013)

The 2010 Cabernet Sauvignon Old Sparky Beckstoffer To Kalon Vineyard is the biggest and most powerful of these wines. It possesses serious depth and power. Layers of dark red and black fruit are woven together in this full-bodied, intense wine. In 2010 Sparky balances intensity with elegance and a totally seamless expression of fruit. Gorgeous, perfumed notes linger on the structured virile finish. This is a great way to end the tasting at Schrader. Old Sparky is built on a core of clone 6, with complementary amounts of clone 4 and clone 337. (Magnum)- Antonio Galloni (12/2012)
