If you and I ― and 10 other people ― all had a glass of the same wine in the same place at the same time, chances are we'd generate a dozen different ideas about what the wine tasted like. Moreover, some in the group would probably say they detected only a handful of characteristics, while others might reel off a long list of evocative adjectives. What's going on here? When it comes to wine, why is taste so hard to pin down and seemingly so different for each of us? (One sad outcome of this conundrum is that wine tasting and evaluating intimidate some of us ― especially when we find it hard to describe what we taste.)
There's no quick answer. What we refer to simply as "taste" is really an intricate phenomenon involving multiple mechanisms in the mouth and brain. Scientists have discovered that our sensitivity to taste is in fact based on our DNA; some people actually do have the capacity to experience flavors more intensely than others. And a leading taste researcher at Yale University has demonstrated that for women, intensity of taste varies with hormonal cycles.
All this complexity notwithstanding, research and experience also suggest that there are simple ways in which you can maximize the flavor of any wine you drink.
Much of what we call "taste" is really smell. Research indicates that while many aromas are detected by nerve cells in the nose (and best absorbed by taking lots of quick sniffs while you're drinking), some ― and here's the surprising news ― are registered at the back of the throat. Conclusion: You need to hold the wine in your mouth for a few seconds and slosh it around a bit to get every smell ("taste").
The sensory organs we call taste buds are contained in onion-shaped structures all over your tongue and soft palate. And it takes time for flavor molecules to penetrate the opening in the top of these structures (which is why we tell children to swallow fast when they're taking a bad-tasting medicine). The moral of the story? If you drink a wine in down-the-hatch fashion, you simply won't get the full impact of its flavor. Again, you have to hold it in your mouth for several seconds (some evidence suggests up to four).
Master the mechanics
Use large glasses with generously sized bowls to give you room to swirl vigorously ― which is the next point: Be sure to swirl every wine more than once. Aerating the wine helps release aromas (and hence flavors). A final corollary to this: Young, tannic reds like Cabernet Sauvignon and Merlot will always taste more profound if you pour them first into a carafe, pitcher, or decanter. Just the act of pouring the wine through the air makes a huge difference.
Skeptical? Try conducting a simple experiment: Taste a wine, intentionally not following any of the suggestions above, then try the techniques. You'll be amazed at how much more flavor every glass of wine can yield.
