(97-99 points) The 2019 Cabernet Sauvignon continues to show brilliantly. (I rated it 97-100 from barrel last year.) It has a quintessential Cabernet nose of pure crème de cassis, crushed stone, lead pencil, graphite, and tobacco that gains depth and richness with time in the glass. Deep, full-bodied, rich, and incredibly textured, yet still fresh, light on its feet, and beautifully balanced, this gorgeous Cabernet shows what's possible with the variety from Paso Robles.

Decanter, February 2023
A benchmark California Cabernet Sauvignon which showcases the strength and tenacity of this revered grape. On the nose, a juxtaposition of expressive, bright fruit plus a grounded earthiness. The delicacy yet force of this wine creates a most pleasant tension that you seek to reconcile with each sip. Flavours of blackberry, bramble and dark chocolate sit side by side with floral and sweet cedar notes. Tannins display laser-sharp integration. A wine with thoughtful, intentional power.

Robert Parker's Wine Advocate, December 2022
The 2019 Patrimony Cabernet Sauvignon was made with free-run juice and matured for 30 months in 100% new French oak. It has a deep ruby color and alluring tones of truffle, brown sugar and coffee to begin, opening with time to very pure cassis, boysenberry, tobacco, garrigue and aniseed. The palate is supple and fresh with surprisingly restrained, mineral-laced fruits and a fan of spicy accents across the long finish. This ultra sleek, elegant Cabernet evolves continually in the glass and has the harmonious structure it needs to go the distance in the cellar. - EB

DAOU Vineyards & Winery history
The estate was established in 2007 by Beirut-born brothers George and Daniel Daou, who had previously built a successful IT business. Daniel has made the transition from engineer to winemaker.
The initial property consisted of a section of land that had once been part of the Hoffman Mountain Ranch. In 2012 the brothers bought the rest of the Hoffman property which increased their vineyard holdings to 86 hectares (212 acres).
The Hoffman Ranch had been the first modern commercial winery in Paso Robles after Prohibition. It was established by Stanley Hoffman with help from prominent Californian winemaker André Tchelistcheff.
Expressions Collection: at the time of writing comprises a single wine The Bodyguard, a blend of Petit Verdot and Petite Sirah (Durif)
