As a certified sommelier with over a decade of experience in the wine industry, I have a deep understanding of the nuances that make each wine unique. When we talk about the characteristics of wine, we're not just discussing taste and aroma, but also the visual aspects that can tell us a lot about the wine's composition and quality. One such visual aspect is the phenomenon known as "legs" or "tears" that many wine enthusiasts and professionals observe when they swirl a glass of wine.
Legs are the thin streams of liquid that run down the inside of the glass after the wine has been swirled. They are a fascinating subject of study for those who appreciate the science behind the art of winemaking. The formation of legs is a complex process that involves several factors, including the wine's alcohol content, its sugar levels, and the presence of certain compounds known as glycerol and surface tension agents.
When you swirl a glass of wine, you're not only aerating it to release its aroma but also creating a thin layer of wine on the inner surface of the glass. As the wine begins to settle, the legs form due to the difference in volatility between alcohol and water. Alcohol evaporates more quickly than water, and as it does so, it creates a meniscus, or a curved surface, that pulls the wine upward, creating the streaks we see. The more alcohol present in the wine, the more pronounced these legs can be.
However, it's important to note that while alcohol content can influence the formation of legs, it is not the sole determinant. The presence of glycerol, a byproduct of fermentation, also plays a significant role. Glycerol is a thicker, sweeter liquid that can increase the viscosity of the wine, making the legs thicker and more persistent. Additionally, the sugar content in the wine can contribute to the formation of legs, as sugar is more viscous than water and can slow down the rate at which the wine flows down the glass.
The observation of legs can be a useful tool for wine tasters, but it's not a definitive indicator of quality. While it can suggest a higher alcohol content or a certain level of sweetness, it doesn't necessarily mean the wine will be more enjoyable. The true measure of a wine's quality comes from a combination of factors, including its balance, complexity, and how well its various components work together to create a harmonious and pleasing experience.
In conclusion, the presence of legs in a wine is a fascinating visual clue that can tell us something about the wine's composition. However, it's just one piece of the puzzle when it comes to understanding and appreciating the full spectrum of a wine's characteristics. As with any aspect of wine tasting, it's important to consider the legs in the context of the whole experience, rather than relying on them as the sole basis for judgment.

--Legs-- are those streaks that trickle down the side of any wineglass after you swirl it (though they might be particularly beautiful in a Riedel glass, they are not exclusive to the brand). The legs are caused by alcohol, so it's thought that the more legs, the higher the alcohol content of a wine.
