A favorite amongst wine lovers, Bottle Shock follows the story of Chateau Montelena’s triumphant victory at the Paris Wine Tasting of 1976. Also known as the Judgment of Paris, this monumental moment was a first for U.S. wine producers and changed the landscape of the winemaking industry in California forever. It also introduced Northern California as one of the premier wine-growing regions in the world.

The film follows wine expert Steven Spurrier (played by Alan Rickman) stumbling upon Chateau Montelena and its owner Jim Barrett (played by Bill Pullman), and Barrett’s son, Bo (played by Chris Pine). Spurrier is shocked to discover the now award-winning Chardonnay and is determined to get the wine back to Paris for the blind taste testing. As with any movie based on a true story, you might be wondering what was fact and what was fiction, so we’re here to share.

FACT: Playfully portrayed by Chris Pine, Bo Barrett, the son of Chateau Montelena’s winemaker Jim Barrett, is an unruly California surfer dude who frustrated his father due to his low ambition. Bo was indeed a surfer and a rebel in the early 1970s, but he has since lived up to the elder Barrett’s hopes: Bo is currently the CEO of Chateau Montelena and has been involved in every vintage at the winery since 1972.

FICTION: The father-and-son duo were a bit less physically violent than the film leads viewers to believe. There is no boxing ring on the Barrett property or in the vineyards, nor did Jim and Bo ever box each other.

FICTION: Though he ended up owning the historic Chateau Montelena Winery, Jim Barrett did not craft the wine that went on to win big in France. Mike Grgich, a Croatian-American winemaker in Napa Valley, was actually the winemaker of the 1973 Chardonnay that won the Paris Tasting of 1976, known as the Judgment of Paris. While originally written into the script, Mike was cut from the movie because he did not want to be a part of the film.

FICTION: In the film, the Chardonnay turns brown for 24 hours after bottling, a twist that devastates Jim, who believes his new release is doomed. Though the wine did turn off-color for a short time after it was bottled, this is actually a somewhat common occurrence, and real-life winemaker Mike Grgich totally knew how to handle the situation.

FICTION: Jim and Bo are shown living at the Napa Valley winery during the summer of 1976, but they actually lived much further south, near Los Angeles, and took long trips up the coast in order to operate Chateau Montelena. Jim was actually a certified pilot, and he often flew into the nearby Santa Rosa airport when he had to spend time at the winery.

FACT: Bo and Gustavo Brambila, played by Freddy Rodriguez, are portrayed as close friends, with Bo as the prankster and Gustavo as the serious one. The two struck up a friendship in the 1970s, although Gustavo was not actually involved at all with Chateau Montelena’s win at the Paris Wine Tasting. Gustavo, one of the first Latinos to earn a degree in fermentation science from the University of California, Davis, was hired by winemaker Mike Grgich to do quality control in 1976, although it was after the famed tasting. Bo and Gustavo remain close friends to this day.

FICTION: In the film, Gustavo is fired by Jim for producing wine under his own label. However, Gustavo was never fired, but instead left the winery on good terms. He actually left in 1977 to work for Mike when the former Chateau Montelena winemaker created his own brand, Grgich Hills. In 1996, Gustavo did go on to create his own label, Gustavo Wine, which continues to operate to this day.
