 We now measure the amount of correlation (W) among the judges:                 
 W = 1.0 => perfect correlation, W = 0 => no correlation                        

 We also provide a probability measure that this correlation is due to chance   

 In this case the correlation is =     0.2489                                   

 Probability that correlation is due to chance = 0.0632                         

  We compute the correlation of each taster with the average ranking of the oth-
 ers. 1.0 => perfect correlation, 0 => no correl., -1.0 => total disagreement

Comments: This was a very interesting tasting as it almost reaches back to
the beginning of Walla Walla Vintners and Walla Walla wine in general.
We all agreed that these wines have matured very well and are very delicious
to drink. Most found that the acidity of the 1999 stood out. Similarly,
the oldest wine of the flight (1997) has oxidization notes
but was still delicious.
