Many people are confused when it comes to decanting. What's it used for? When should I do it? What is it exactly?
Decanting helps take out sediments that may have settled in the wine, to air out (thus oxygenating) the wine, change the wine temperature, and helps make wines more fuller-bodied.
Usually, people decant wine that is over 10 years old.
If you can't get a decanter, don't worry. Using a glass vase or pitcher has the same effect - and it may even be prettier!
