How to buy a wine decanter
Choose a wide neck decanter for ideal aeration.
Before serving is one of the primary purposes of a decanter. A wide neck decanter will give your wine more exposure and bring out more flavors within your wine.
Because you'll be able to taste more, wide neck decanters are great for making young wines taste complex. Wide neck decanters are also better for cheap wines, as aeration will make the wine taste richer.
