A little known fact about tasting wine is that your nose is the key to your palate. It’s true that a large amount of your satisfaction in a wine comes from smelling it before you take a sip. The smell of a wine can be delicate or strong, pleasant or unappealing, but before you dive in, be sure to swirl the wine a bit to bring out the aromas. This aerates the wine by adding oxygen to it, letting it “breathe” so it opens up and reveals the goods. So swirl away, then stick your nose into the glass and take a big whiff. What do you smell? Fruit, earth, dried herbs, sulfur? Certain grapes and certain places will have unique smells, while production techniques can impart additional aromas, as well. These can be broken down into categories:
Primary Aromas: These are grape-derived aromas and include dominant fruity, herbal, and floral notes.
Secondary Aromas: These aromas are background aromas that come from the winemaking practices, like fermentation techniques. Think buttered brioche, cheese rind, nutty characteristics, or yeast-like aromas.
Tertiary Aromas: These come from aging, whether from oak or in the bottle, and include notes of vanilla, coconut, baking spices, roasted nuts, tobacco, cigar box, and leather.
Look for aromas that smell like wine (fruit, earth…) instead of something funky, the latter of which could mean the wine isn’t in good condition. A few indicators that the wine is off include the smell of must or wet cardboard, barnyard/wet horse, rancid butter, matchsticks, and mothballs. Some of these flaws could be the result of a problem with winemaking, while others are caused by improper handling and storage.
