Key ideas in Decoding White and Red Wines
- Acidity triggers salivation which cleanses the palate after rich fruit
- Residual sugar is unfermented grape juice that adds physical weight
- High acid provides a 'spine' that prevents ripe wines from tasting cloying
- Fruitiness is an aromatic perception, not a measure of actual sugar content
- Low acidity results in a 'flabby' mouthfeel where flavors lack definition
- Dry wines can smell 'sweet' due to ripe fruit esters without being sugary
- Identifying the role of acidity in balancing fruit and structure
- Distinguishing between aromatic fruitiness and physical residual sugar
- Alcohol increases the viscosity and 'legs' of a wine on the glass
- Higher alcohol content creates a heavier, more coating mouthfeel
- Cool-climate wines like Riesling typically have lower alcohol and body
- Categorizing wine body based on alcohol-driven viscosity
- The finish measures how long pleasant flavors persist after swallowing
- Premium wines show an 'evolution' of different flavors during the finish
- A short, 'clipped' finish is a hallmark of simple, mass-produced table wine
- Evaluating quality based on the length and evolution of the finish
