Someone opening a single bottle and ascribing some mystic cause for why it shows poorly compared to the bottle opened 3 months prior is a bizarre superstitious conceptualization. Young wines go through cycles of change, independent from each other. Another bottle from the same case, opened at the same time can show quite differently. So, is one bottle having a root day and the other having a fruit day? Maybe Dionysus is punishing you for not performing some ritual before opening the bottle.
Yup. This.
