Decantation: Before a bottle of Barolo can be drunk it is best to be decanted using a decanter. A decanter is a glass jug that is wider at the bottom than at the top. ... Taste the wine after one hour of decanting it, if the flavors still don't come out, leave it for two more hours.

Does Barolo need to breathe?

As the years have gone by, I have come to the view that a well-cellared bottle of old, traditionally made Barolo should breathe for at least an hour or two before drinking. This applies especially to Barolos in their 30s, 40s and 50s.

How long should Barolo be decanted?

High-Tannin, Bold Reds: Decant intense, tight wines like Cabernet Sauvignon, Syrah, and Barolo for about two hours (unless they are more than 20 years old or already taste superb).
