2021 was an excellent vintage in South Australia (you may tire of reading that soon), and this 2021 Riesling Old Vine shows the effects of a long, cool, even ripening season. In the mouth, the wine is austere and restrained—it curves along the track with a fine web of acidity within the lean fruit. The vines were planted in 1974 on terra rossa soil, which imbues the wine with a density of structure and minerality of flavor. There is a lemongrass/weed character through the finish that I am uncertain about; perhaps in a year or two the wine will have evolved past this.
