What Does Aerating Wine Even Do?

Aerating? Decanting? English, please!! All these wine terms can be hard to keep straight, and even harder to understand. So what does it mean when you aerate your wine? This is basically just a fancy word that wine connoisseurs use to explain letting your wine breathe, which can seem like a weird concept since wine isn’t alive. And even that’s a simplified version. Aeration really means taking the time for your wine to oxidize and evaporate.

When choosing which wines to aerate, a good rule of thumb is to only aerate and decant (don’t worry, we’ll explain decanting in a hot sec) reds, not whites. Reds have more tannins, which is better for aeration as it smooths out the flavors. #Science.

The nitty gritty of aerating

Little did you know, every time you open a bottle, you’re aerating it! Even as you’re pouring your wine into glasses and swirling it around to let out all the aromas, you’re aerating it the whole time. When wine is exposed to air, it triggers the process of oxidation and evaporation. Oxidation is the result of a chemical reaction when something is exposed to oxygen (think apple slices browning when left out too long). Evaporation is when liquid turns into vapor and escapes into the air, as you’re probably all too well aware from your third-grade science classes.

Now don’t panic. Your precious wine isn’t going to magically evaporate into thin air if you don’t drink it fast enough. This form of evaporation refers to the undesirable components of wine evaporating, leaving behind the good stuff. The dynamic duo of oxidation and evaporation that makes up aeration will eliminate certain elements in your wine while enhancing others at the same time. As a result, your wine will smell and taste a lot better. And I don’t know about you, but I’m all in for better tasting wine.  

By now you’re probably wondering what wines will benefit from aerating. I mean if it makes wines taste and smell better, why wouldn’t you aerate all wines? Valid question. Not all wines do well with aeration though, especially white as we mentioned earlier. Dense red wines that are full-bodied will do better with some air. The reason being that these wines can go a longer period of time exposed to oxygen without (gasp) losing flavor.

What is decanting?

So then what’s decanting? It might sound like the opposite of aerating, but it’s actually a typical step in the process of aerating a wine. Simply stated, decanting is transferring (decanting) the contents of a wine bottle into another container (the decanter) before serving. Confused? Basically, you can use a decanter to help aerate your wine.  

One of the oldest methods to aerating wine is to use a decanter. A decanter is that funky-looking, large bottomed pitcher that almost resembles a vase. The science behind its shape is that the increased surface area at the bottom of the decanter allows your tannin-filled red wine to be exposed to as much oxygen as it can. So while you can let your wine breathe from the bottle itself, the narrow neck really won’t allow much air to get in. We recommend pouring that bottle into a decanter so that your wine will be ready ASAP.

Another plus to a decanter is that it looks elegant AF (and like you know what you’re doing, because let’s face it, you do!). Don’t have a decanter around? Don’t worry. Instead, pour your wine into large wine glasses and let them breathe for 10 to 20 minutes. We know, that seems like forever to wait for your wine. We feel your pain. So while you’re waiting, you can educate your guests on all your newfound knowledge about how essential it is to let their wine breathe. Or you can look up funny memes (like this one) about aerating wine.

Cheers!
