Relentless means "merciless."
It represents the uncompromising attitude of Elias Fernandez, the talented winemaker who has supported the winery for many years.
The 2008 vintage was named Wine Spectator magazine's highest honor, "Wine of the Year 2012," attracting worldwide attention.
In 1972, the late John Shafer gave up a glamorous career in publishing to found the winery in the hillside neighborhood of Napa Valley's Stags Leap District.
John, who knew nothing about winemaking, began by reading every book on winemaking he could get his hands on in order to create his ideal wine.
Later, the eldest son, Doug Schafer, who studied oenology, and Elias Fernandez, who is now a talented winemaker, joined the company, and the quality of the wines has become unwavering.
