exist, correlations between the various sources are generally strong (r > 0.9) indicating that this subjective measure of quality is a good quantitative representation of a vintage (Jones, 1997). Vintage ratings are usually based upon a collection of estimates from one to five or seven classes (from exceptional to bad) and quality scores or ratings that range from 0–20 or 0–100 (with higher values indicating higher quality). Ratings may represent the score for an individual wine from a single winery or chaˆteaux, or a general region-wide average score. Wines are typically rated by single judges or a panel, which attempt to qualify the vintage- to-vintage nuances of flavor, aroma, and color and the wine’s balance of alcohol and acidity that together best represent that variety’s wine style.
