"A barrel sample of 86% Syrah and 14% Petite Sirah, the 2017 Relentless is deep purple-black colored and seductively scented of stewed plums, black tea, Sichuan pepper and salami with a core of blackberry pie, sautéed herbs and tar. The palate is full-bodied, firm and chewy with lively line and peppery finish." 90-92 pts, Lisa Perrotti-Brown, WA
"The 2017 Relentless is a bold, flamboyant wine that seems to have put on even more density over the last year, hard as that may seem to believe. Black cherry, licorice, spice, leather and menthol are all amped up in this decidedly opulent, full-throttle Syrah-based wine." 90-93 pts, Antonio Galloni, Vinous
