94 points James Suckling: "This is a very composed and nicely layered rendition of this top-end shiraz with aromas of cocoa, dark plums, blackberries, cinnamon, licorice and dark cherries. The palate has a very impressive build of ripe dark-fruit and chocolate flavors. Layered and expansive, it swells impressively through the finish. Smoothly resolved and gently spicy. Drink or hold. Screw cap. (5/26/20)"
94 points Wine & Spirits: "[$65 list] Only Chester Osborn would name his icon wine after a disease, in this case, eutypa dieback, caused by a wood fungus that eventually kills off a cane on an old vine, leaving a dead arm that needs to be cut away. His collection of old-vine shiraz parcels include a lot of vines with dead arms, which then concentrate their efforts on the fruit they grow on the arms that remain. This 2017 shows that concentration in a stately, plump wine, radiating sun from its blue-black fruit and contrasting earthiness in its rooty, radish-like tannins. Supple and elegant, this has the stature to age with grace. (Feb 2021)"
92+ points Joe Czerwinski (Wine Advocate): "[$65 list] Locked up tight and ungiving on the nose, d'Arenberg's 2017 The Dead Arm Shiraz is nonetheless formidably dense and concentrated on the palate. Notes of charred wood join plums, raspberries and black olives in this full-bodied effort. With its current surly disposition, it appears to require decanting or several years' sleep in a cool cellar. Giving it air helped bring out purple raspberries and softened the considerable tannins, so I'm optimistic about its future evolution. Drink: 2024-2040. (May 2020)"
