The 2017 Chardonnay is relatively plush on the fruit spectrum but propped up, as always, by an austere line of acid and spice. The term "austere" in this case (and every application of it in the context of Xanadu) only references the blocking of malolactic fermentation and its preeminence in the wines on release. The acidity, while austere, is ripe and juicy—which is an important distinction. This is chalky and reminiscent of cheesecloth—there's a lanolin character present here that is not present in the other wines. It also has a note of enoki mushroom. This seems to have plenty of time left to go, but knowing what I know of the 2017 vintage in Margaret River, despite the cool conditions, it may be better to drink this vintage in the medium term rather than long term.
