Help Me Plan Infanticide (Valentini, Pegau, Cosme)

I have three wines that should be saved, but two must be drank in the next 6 months. I can probably hold the third wine for about 3 years.

They are:

Valentini Trebbiano d’Abruzzo 2016
Pégau Châteauneuf-du-Pape Cuvée Réservée 2017
Château de Saint Cosme Gigondas 2017

Have never tried any of these SKUs before. I am looking for reference experience, and I enjoy trying wines young.

Which two should I drink now, and how would you recommend I handle them (eg. open bottle X hours prior, or decant and sip slowly, etc etc)?

I drank a Chave Hermitage young once and it was enjoyable and very interesting. Whereas drinking nearly any Barolo young has been a total waste. So basically I’m looking to identify the one wine here that would not really give any pleasure or indication of its potential at this point, and hold that one.

I’d bet on the Valentini.
