Very interesting, two quite different styles of Shiraz.
The 2021 has a lighter and more advanced colour and development than you would expect from the 1 year difference. It's savoury and mellowing rather than fruit driven and the acid pokes out a little. Despite the high a/v (15.5%) it isn't showing any signs of over-ripe fruit. Other than that, it's a decent $15 ready to go drink of no great distinction.
The 2022 has better, denser colour, nice fruit and oak on the nose, nicely ripe fruit on the palate, no signs of prunes or portiness, fresh and with good tannin structure, better balance than the 2021.
After tasting the two samples, the better half preferred the 2022 and I extracted the cork and was very surprised is was the cheap agglomerate style with just a thin layer of proper cork at each end. Astounding that a cork like that would be used on a supposedly premium wine.
Happy to drink these at the delivered price, but not going back for more, especially after seeing that cork on the 2022. I can't tell if the 2021 has a similar cork or not.
Caveat: I'm not fussed by a bit of alcohol warmth and I don't find it a negative feature on either of these, your experience may be different.
Update: The 2022 is currently shown as sold out, 2021 still available.
