Decanting is the process of transferring wine from its original bottle into a decanter or other serving vessel. It is used for two main reasons: to separate an older wine from sediment or to expose a young wine to air. The method and amount of aeration should suit the wine’s age, structure and condition.
Older red wines and Vintage Port may develop deposits during bottle ageing. Stand the bottle upright well before service so the sediment settles. Open carefully, then pour slowly into a clean decanter, using a light source behind the bottle neck to see when sediment approaches. Stop pouring before the deposit enters the decanter.
Young, structured wines such as Barolo, Cabernet Sauvignon and some Syrah may benefit from air exposure. Pouring into a decanter increases the wine’s contact with oxygen and can help release aromas. The time required varies; taste the wine periodically rather than relying on a fixed number of minutes or hours.
Decanting is not necessary for every wine. Delicate older wines can fade quickly after exposure to air, while many fresh whites and light reds are best served directly from the bottle. Some wines may be decanted briefly for presentation or to remove a closure or bottle deposit.
Example: decant a mature Vintage Port slowly to leave the sediment behind, or decant a young Barolo to encourage it to open before service.
Chef’s tip: use a clean, odour-free decanter and handle older bottles gently. Do not decant a fragile wine far in advance without tasting it first.
Decanting is the physical transfer of wine into another vessel. Aeration is the exposure of wine to air. Decanting can provide aeration, but a wine can also be aerated in the glass without being decanted.
