What You Need To Know
When you open a bottle of red wine, you can either wait the standard 10 to 30 minutes for it to “breathe,” or you can use a new device called a wine aerator. Held above a wine glass or inserted into a bottle, these devices are designed to expose the wine to air while you pour, speeding up their interaction, a process that can improve the flavor of wine.
We poured a 2005 Bordeaux through five brands of aerator to see if any could eliminate the bitter taste of young red wine. In a blind tasting, we compared the wine a glass at a time—one poured through an aerator, the other straight from the bottle. Tasters noticed a difference in the wine’s flavor and aroma, but some devices made a bigger difference than others.
What was happening? When wine is exposed to air, it can alter it for the better. The interaction of wine and air makes an impact on highly volatile chemicals such as sulfur compounds, which can produce a harsh taste, and free acetaldehyde, which can confer flatness in wine. Sulfur compounds can be detected at very low levels, in the range of parts per billion, and some of them react with oxygen to become less volatile substances with different odors. (There’s no evidence that aeration changes the level of tannins, which gives wine its astringency, because tannins are not volatile.)
Tasters unanimously agreed that one aerator stood out for markedly improving flavor and aroma, increasing fruitiness, opening up the wine’s bouquet, and smoothing harsh notes. The winner, which looks like a perforated cigarette holder covered in black rubber, disappears into the neck of the bottle, leaving only a stainless steel pouring spout visible. As you pour, air is drawn into the wine through a narrow tube enclosed within. For aerated wine without waiting, this product comes in handy.
Everything We Tested
Tasters agreed that this long, tubelike aerator, which resembles a cigarette holder, made the impact on wine. It brought out “fruity flavors” and a “pronounced floral” aroma. The device slides into the neck of the bottle, leaving only a pouring spout, for neat, hands-free aerating.
This device, which resembles a child’s top, attaches to the opening of the bottle and spins wine around a chrome spiral, drawing in air through the top of the chamber. It softened the wine and brought out a “deep fruit” flavor, but the difference was less pronounced than with the top-rated Nuance.
Except for the pinholes in either side, this plastic aerator could pass for a shot glass. Placed over each wine glass, it draws air into wine with an audible hiss as you pour. While it’s messier to use than models that attach to the bottle, this device brought out a “bright and strong” aroma and “more fruit flavor.” Comes with a stand that holds the device (and catches drips) between uses.
Recommended with reservations
“There’s not a big difference (in flavor),” commented one taster. This perforated funnel rests on top of the wine glass and sprays wine like a fountain into the glass. This handheld device was not as easy to use as models that attach to the bottle. It includes a metal stand for resting between uses.
This battery-powered aerating wand bubbled air into the bottle for a minute through a thin, metal tube, then shut off automatically. Testers were frustrated that the device could not be switched off, and we disliked that it required batteries. Tasters noticed a slightly smoother taste, but also commented on a “lack of flavor” and “dullness.”
