Pouring wine into a decanter just feels good. It's a little dramatic, a little old-world, and it instantly turns dinner into an occasion. But beyond the theatre of it, decanting actually does something quite wonderful to the wine itself.
What a decanter actually does
Traditionally, decanters were used to separate wine from sediment that develops in the bottle over time. You'll still find sediment in older reds, or in wines that haven't been heavily filtered. Most modern wines are made to reduce this, but decanting earns its place at the table for a more exciting reason. It helps wine taste better.
The secret is aeration, which is a fancy word for letting the wine breathe. When wine meets air, a gentle chemical reaction begins. Firm tannins (that slightly drying sensation on your gums) start to soften, and hidden aromas begin to lift out of the glass. It's like waking the wine up from a nap. Suddenly you can smell more fruit, more spice, and more of those subtle earthy or floral notes that make a wine genuinely interesting.
A bigger stage for the wine to perform on
Think of swirling your wine in the glass. It helps the wine open up. A decanter takes that idea and gives it a much bigger stage. By spreading the wine out and increasing its contact with air, you give the whole bottle a chance to relax and show its personality, not just the glass you're holding.
Balance is key. A gentle introduction to oxygen can transform a wine from tight and shy to smooth and expressive. Leave it exposed for too long and it can lose some of its freshness. But when you get it right, the difference is surprisingly noticeable. Softer texture, brighter aromas, more layered flavour.
Which wines benefit most?
Decanting is particularly rewarding with structured reds. Think Cabernet Sauvignon, Bordeaux blends, Shiraz, or a rich Port. These wines often have more tannin and benefit from a little breathing space.
Here in the Margaret River Wine Region, we are lucky to be surrounded by exceptional Cabernet Sauvignon and elegant Bordeaux-style wines that absolutely sing after time in a decanter. That beautiful balance of ripe fruit, fine tannins and coastal influence becomes even more harmonious with a bit of air.
Even younger wines benefit from twenty to thirty minutes of breathing space. If a wine tastes a little tight or muted when first opened, giving it room to move can help it blossom. It's a simple step that can lift a midweek bottle into something far more special.
The other half of the equation: the right glass
Aeration doesn't begin and end with the decanter. The shape and size of your glass plays just as big a role in how a wine shows up. A wide bowl gives big reds room to open up. A narrower flute keeps a sparkling wine fresh and lively. The right glass can be the difference between a wine you drink and a wine you genuinely enjoy.
Plumm wine glasses are an Australian favourite of ours, designed with the same considered approach a sommelier would take. The Plumm Vintage REDa is built for Bordeaux blends and Cabernet, exactly the wines our region is known for. The Plumm Vintage SPARKLING brings out the toasty notes in champagne and our local sparkling. And the Stemless range is a relaxed pick for casual dinners and outdoor entertaining.
Part science, part ritual
There's also the experience itself. Decanting invites you to slow down. To pour with intention. To gather around the table and anticipate that first sip. It is part science, part ritual, and entirely about enjoyment.
Not every bottle needs decanting. But when the moment calls for it, a decanter, or simply a beautiful glass, enhances more than the flavour. It enhances the whole occasion. And really, isn't that what good wine, especially from somewhere as special as Margaret River, is all about?
