Barolo has a long shelf life, especially if it is from Marchesi di Barolo or Giacomo Borgogno. You don't need to have a great vintage for a lot of fun.
The Marchesi di Barolo 1955 Barolo Gia Opera Pia is still a fresh and fruity wine with cherries, Amarena and herbs. It is medium to full-bodied with fine melted tannin and a medium to long finish. It seems to be much younger. 18.5/20 points.
The Giacomo Borgogno 1955 Barolo Riserva didn't have the fruit and freshness of the Marchesi but it was more powerful and evolved in the decanter. It showed malt, herbs, a bit of peppermint, fig and plum and reminded us of a high-class Amarone. It is full-bodied with plenty of melted tannin and a great density. 18.5/20 points. The Barbaresco Riservas from Giacomo Borgogno have the same quality level in generl. They have perhaps a little less tannin and a bit more elegance, but they are just as long lasting.
