The 2005 Cabernet Sauvignon Hillside Select continues to put on weight, and displays a Bordeaux-like personality because of the vintage’s cool growing season. A black purple color, stunningly sweet fruit, and a gorgeous bouquet of underbrush, forest floor, creme de cassis, lead pencil shavings, and toasty barrique are found in this ripe, full-bodied, deep, stunningly well-balanced, substantial wine with undeniable complexity as well as richness. It is approachable now, but promises to evolve for 25 or more years. Celebrating 30 years of consistent quality and both critical and commercial success, this family run winery remains one of the most admirable operations in California. The Shafers have had tremendous success with their Relentless, which was first released in 1999. A blend of 80% Syrah and 20% Petite Sirah that spends 32 months in 100% new French oak, it is a remarkably consistent offering that rarely displays much oak. The Syrah is from Napa’s cool-climate Oak Knoll sector. One of the world’s most prodigious Cabernet Sauvignons is Shafer’s 2,000-case cuvee called Hillside Select. Always 100% Cabernet Sauvignon aged in 100% new French oak for a whopping 32 months, it boasts a gorgeous track record dating back to the early nineties, and just about every recent vintage has flirted with perfection. - Robert Parker

(14.9% alcohol): Dark, bright red. Very fresh on the nose but more reserved and much less explosive today than 2004, offering aromas of black cherry, cassis, dark spices and licorice. Then superconcentrated and tactile on the palate, conveying a lower-pH impression than the 2004. This extremely intense wine still needs time in the cellar to open--and to absorb its vibrant acidity--but the tannins here are fully ripe and suave. Still a bit youthfully stunted but a wine of outstanding energy and incipient savory complexity, with a great future ahead of it.- Stephen Tanzer (07/2016)
