The purpose of a wine rating system is to quantify a wine’s quality separate from those factors that influence pricing. The rating systems vary with some based on a 50-100 point scale, others are a 5 point scale. When looking at these ratings, the evaluation of wine is subjective. Factors that influence the rating are: bottle variability, tasting conditions, judges’ likes and dislikes. Ratings are a helpful guideline when you become familiar with the rater’s preferred style.
