Decanting is the process of pouring wine from its original bottle into a separate container, typically a glass decanter. This age-old practice dates back to ancient Rome, where wine was often stored in amphorae and decanted into smaller vessels for serving. The primary purpose of decanting is to separate the wine from any sediment that may have formed during the ageing process. However, decanting also serves another crucial function: aeration.
When wine is exposed to air, it undergoes a process called oxidation. This chemical reaction can have a profound impact on the wine's aroma, flavour and overall character. By decanting wine, you're essentially allowing it to "breathe" and interact with oxygen, which can help unlock its full potential.
The benefits of aeration are particularly noticeable in young, tannic red wines. Tannins are naturally occurring compounds found in grape skins, seeds and stems, which can impart a bitter, astringent taste to wine. Aeration helps soften these tannins, resulting in a smoother, more approachable wine.
On the other hand, older wines can also benefit from decanting, albeit for different reasons. Over time, wines can develop complex, layered aromas and flavours that may be masked by the initial "bottle stink" – a term used to describe the musty, closed-off smell that can sometimes be present when a bottle is first opened. Decanting helps dissipate these off-odours, allowing the wine's true essence to shine through.
Now that you understand the benefits of decanting, it's time to put this knowledge into practice. Here are some tips to help you master the art of decanting:
Decanting is a simple yet powerful technique that can transform your wine drinking experience. By allowing your wine to breathe and separate from any sediment, you'll be able to enjoy its full range of aromas, flavours, and complexities. So, the next time you uncork a bottle, consider giving decanting a try – your taste buds will thank you!
Red wines, especially Cabernet Sauvignon, Merlot, and Shiraz; White wines with high tannins, such as Cabernet Franc and Petit Verdot; Port; Sherry and; Aged wines. If you are not sure whether or not to decant a wine, it is always best to err on the side of caution and decant it. Decanting will not harm the wine, and it will likely improve the taste!
