To decant or not to decant…

by Jess Ruciack

To decant or not to decant… this is a question we often receive at Elderton regarding our red wines.

Firstly, what is decanting?

It is the function of pouring a bottle of wine into another glass container and serves two main purposes: keeping sediment out of your glass, and aerating the wine.

Sediment – can form in older bottles of red wine, as the colour and tannins bind together and start to ‘drop out’ of the wine. Having these in your glass can result in some bitter flavours and a gritty texture in your mouth, so you can decant and keep the sediment in the bottle and away from the wine. You’ll need to decant very slowly and keep a close eye on the bottle to stop pouring as soon as you see sediment near the neck. You may lose a little bit of remaining wine, but this is a better result than tasting the sediment.

Aerating – Some, but definitely not all, wines need some time to ‘open up’. When oxygen is able to get in and around the wine, it starts to oxidise, which can make the wine seem more expressive and aromatic. It doesn’t change the tannin structure of the wine, but does allow some of the volatile compounds to evaporate, leaving the wine to appear more balanced and enjoyable.

You may also need to decant if you had a cork malfunction and don’t want bits of cork in your glass. This is where keeping a small sieve in the kitchen comes in handy.

So back to the question – To decant or not to decant?

The easy answer to this question is that there is no easy answer! However, here are a few pointers from Decanter Magazine that will hopefully get you going in the right direction:

• Generally speaking some aeration is better than none, although we do understand that you may be desperate for a drink!
• Simply opening a wine and leaving it in the bottle for a few hours will have little effect on the flavour of the wine.
• Younger wines should be decanted for a longer period (1 – 2 hours), and the process of decanting can be a touch rougher (you want the wine to receive oxygen to open it up).
• Older wines need to be decanted gently (to remove any potential sediment), and for a short amount of time < 1 hour only. Too much time and the wine may fall apart.
• Very rich wines can shed some of their puppy fat from longer decanting, but will lose some of their freshness.
• You cannot resuscitate a wine that is already past it through decanting.

Another great tip, learned through experience, is that you don’t need to spend lots of money on a decanter. Some are certainly gorgeous pieces of art (like the Riedel decanter my husband bought me a few years back), but something as simple as a jug or a conical flask can do the job. Your chemistry teacher didn’t give you that gem of advice though, did they?

When I’m drinking the Neil Ashmead Grand Tourer Shiraz, I like to decant for at least an hour (then I taste it and see how it’s going, depending on the vintage it might need some more time). For my personal taste, I like how the wine opens up after some time in the decanter. And it is delicious!

For best drinking pleasure also, we here at Elderton recommend serving the wines at the correct drinking temperatures (something we often don’t do well in Australia). When we say cellar temperature we would ideally like our red wines served around 18 degrees Celsius.

As always though, it is each to their own

Don’t let this blog put you off – if you are happy drinking wines in a different manner, continue on.

Wine is an individual thing, and nothing upsets us more than wine snobbery. Basically, do what makes you happy – especially if it is drinking Elderton!
There is no ‘best wine’ – it is simply about what you enjoy drinking.
