Abstract
The responses of a panel of expert judges were measured over 14 years. Their abilities to distribute their scores normally on an unbalanced score card and a balanced score card were tested. In some instances it took years for a panel member to adjust to the score card so that a normal distribution of his score resulted. With the balanced score card a normal score distribution resulted in the first year of use. The ability of judges to repeat their scoring on the same wine was tested for this extended period. The ranges of score (2 to 98%) used each year were also measured. It was determined that a ratio of the individual judges 96% score range to the standard deviation was a fair single measure of the judges ability to use the score card effectively. Of the six judges who tasted over the extended period, only one had a concept of quality significantly different from that of the others. The individual panel members stabilized in sensitivity after about five years of training. The yearly panel mean score values declined almost one full point before stabilizing, after seven years. Other statistics are included.
