This powerful, rough-hewn wine that contains 11% Petite Sirah holds extremely deep black and blue fruits in a framework of grippy tannins. A tight, reserved expression on the midpalate signals more aging is needed for best enjoyment. The wine's ripe, compelling, late-harvest fruits match the massive structure. Best from 2028–2040.

The 2019 Relentless is mostly Syrah, yet the cuvée always includes a good bit of Petite Sirah, with 11% in the 2019. A deep purple-hued blockbuster of a Syrah, it offers loads of ripe blackberries, ground pepper, sappy herbs, and violet-like aromas and flavors. One of those wines that delivers richness and intensity with no sensation of weight of heaviness, it has terrific balance, ripe tannins, and a great finish. Enjoy bottles over the coming 10-15 years.

The 2019 Relentless is gorgeous. Bright and intensely savory, the 2019 bristles with energy. Black pepper, sage, tobacco, incense and dried herbs lend tons of nuance to this expressive Syrah/Petite Sirah blend. There's quite a bit of energy here and also a bit less heft than most previous vintages, a reflection of a move towards slightly cooler sites.

The 2019 Relentless is a blend of 89% Syrah and 11% Petite Sirah that spent 30 months in 100% new French oak. The nose is a bit briary, with intriguing herbal complexities from the Syrah, vibrant purple-raspberry fruit and perhaps some blueberry fruit from the Petite Sirah. This is full-bodied, tannic, sturdy stuff that needs time to come around, but as it's packed with fruit, that shouldn't be an issue. Patience will be required.
