Thats putting it mildly to say the least! LOL
From the Bottle Shock Wiki page:
Controversy[edit]
Steven Spurrier himself has questioned the accuracy of the script while he was involved in another movie project depicting the events of the Judgment of Paris, stating: "There is hardly a word that is true in the script and many, many pure inventions as far as I am concerned. It's deeply insulting".[2]
While the film depicts Gustavo Brambila as being at Chateau Montelena throughout the events leading up to the Judgment of Paris, his 22-year term at Montelena actually began just after the tasting.[3] While at Chateau Montelena, Brambila worked closely with Mike Grgich – who, although not depicted in the film, was the winemaker behind the 1973 Montelena Chardonnay that won in Paris.[4]
