Yeah, I agree with TS on the Plowman, while the fruit is good, it's soft and very medium-bodied, with only a little fine tannin and fairly low acid level indicating only short-term cellaring, it is drinking quite nicely as a young wine though.
In a recent tasting it ranked down the back end of a set of 6, with Ch Tanunda Terroirs Eden Valley 2018, Yangarra Kings Wood 2019, Haselgrove The Ambassador 2017, Thorn-Clarke Ron Thorn 2017 and Epic Negociants Apollonian 2019 all more impressive. I was a little underwhelmed by the Ron Thorn after all the hype, big old-style Barossa Shiraz, but this bottle showing some volatility (cork sealed) and a slight hard edge to the tannin.
