Unlocking the Secrets of Wine: Density and Concentration
Diving into the world of wine tasting, one discovers a palette of sensory experiences that transcend mere flavor profiles. Today, we delve into two pivotal concepts: density and concentration. These terms, often overlooked, play a crucial role in understanding the complexity and character of a wine.
Concentration: The Essence of Complexity
Concentration in wine is akin to reading a rich, layered novel. It refers to the amount of extract in the wine, a combination of elements that contribute to its depth and intensity.
This extract, often measured as “dry extract” in wineries, represents the residue left after water evaporation. Further refining this measurement, some laboratories calculate the “sugar-free dry extract,” discounting the sugars to focus on other components.
Concentration is not just a technical term; it’s a sensory journey. It’s enhanced by various winemaking techniques such as the extraction of polyphenols, aging on lees, and the use of new oak barrels. These processes infuse the wine with a complexity that’s sensed as richness and depth in every sip.
Density: The Feel of Wine
Density, on the other hand, is the tactile experience of wine, often described as its weight or viscosity. It’s about how the wine feels in your mouth – its texture and thickness. Influenced by the density of each component, like ethanol, sugars, and glycerol, density adds a physical dimension to tasting.
Ethanol tends to lighten the wine, while sugars and glycerol contribute to its viscosity. Interestingly, our perception of a wine’s thickness might be linked to unidentified taste receptors.
For instance, receptors reacting to linoleic acid (found in oils like sunflower and soybean) hint at our ability to detect fat-like substances in wine.
This intriguing aspect of sensory science enhances our understanding of wine’s body – a term often used interchangeably with density and concentration, yet signifies their harmonious blend.
