Another fantastic tip to have in mind when you are a Gourmet Hamper Providore. Decanting wine.
For sure, you have a few bottles under the stairs or have left some in the cellar for a little too long, and would like to get some value from them. Try decanting your wine before drinking. There is no mystery behind decanting wine; simply pour the wine into a carafe and let it breathe a bit before serving. Decanting a wine both removes the unappealing and bitter sediment at the bottom of an old bottle and allows the wine to breathe.
Uncork the wine and pour it slowly into the carafe making sure that the sediment stays undisturbed at the bottom of the bottle. When complete, you should have about half a glass of wine left in the bottle.
