I only bought the one to try from TWC in a mixed order. In my experience out of balance acid seldom sorts itself out with age, although sometimes other changes in the wine may make it less distracting. For fun google something like "acid in wine changes over time", this is the first part of the "AI Overview":
Yes, the acidity in wine does change over time during the aging process, although the total measurable amount of acidity remains relatively constant. The perception of acidity, however, can change due to various factors, including the formation of esters, changes in tannins and phenolics, and the conversion of acids.
Also in the results:
How does bottle aging affect the acidity of wine?
The type of food the wine is consumed with can also affect the perception of acid. My tasting was with cheese/biscuits and then moderately spicy Thai food, didn't work with those.
We often drink Shiraz with spicy Thai food, many Aus Shiraz do work well for us. In fact tonight we will be drinking a 13 yo Mitolo Shiraz with a gum-searing Kua Kling Moo (Southern Thai dry-fried pork mince with special turmeric-rich paste smothered in finely shredded makrut leaves).
