96 Points - Robert Parker's Wine Advocate:  The 2018 The Signature Cabernet Sauvignon Shiraz (the 48th vintage) is named for Nick Waterman (managing director and CEO of Yalumba 2015 - 2022). The 2018 vintage in South Australia (and specifically here, Barossa) was an excellent one: ripe/warm, even and long and produced wines with density, energy and gravitas. This is exactly that: plush and powerful. The fruit forms a perfect dovetail: the enveloping, mouth-filling abundance of the Shiraz, neatly wedged into the folds of the structuring and shapely Cabernet. Very impressive. This is one of the more impressive Signatures in recent times. It will cellar with grace and ease.

96 Points - James Halliday:  Since its first release in 1962, The Signature has been Yalumba's deep dive into the classic Australian blend from the Barossa and one that honors the people who have enhanced the traditions and culture of Yalumba. There is a resonance and depth to this release that I really like. Wonderfully pure and concentrated blackberry and plum fruits, layered with spice, dark chocolate, earth, cedar and oak nuance. Succulent and sinewy in the mouth, it flexes considerable muscle, yet remains purely fruited and approachable even at this stage of its evolution. Rich and balanced with fine, ripe tannin and plenty of energy for such depth of fruit. Lovely.
