This was my last remaining bottle of the 1998 Grenache Cornerstone and I had doubts about whether it would still be holding on. However, there was no problem whatsoever. It is still a vibrant, exuberant, full-bodied wine with beautiful kirsch liqueur, earth, spice box, pepper, and underbrush notes. This sensational Grenache could easily stand up against some of the finest from Southern France. Readers who have some of this beauty in their cellars should consume it over the next 1-3 years. You won’t be disappointed.This has always been one of my favorite Barossa wineries - great proprietors, tiny yields, old vines, and a hands-off style of winemaking. Of all the flights we tasted, these stood out as the most riveting wines of the entire tasting. The Shiraz cuvees were off the charts - every one still young and not close to full maturity. These are all high octane wines (14.5-16% alcohol), but any evidence of wood (little new oak is used here except for the limited production Roennfeldt Road cuvee) is completely buried under the aromatic complexity and richness.
