In some advertisements, the Champagne houses catered to political interest such as the labels that appeared on different brands on bottles commemorating the centennial anniversary of the French Revolution of 1789. On some labels there were flattering images of Marie Antoinette that appealed to the conservative factions of French citizens that viewed the former queen as a martyr. On other labels there were stirring images of Revolutionary scenes that appealed to the liberal left sentiments of French citizens. As World War I loomed, Champagne houses put images of soldiers and countries’ flags on their bottles, customizing the image for each country to which the wine was imported. During the Dreyfus affair, one Champagne house released a champagne antijuif with antisemitic advertisements to take advantage of the wave of Antisemitism that hit parts of France.
Champagne is typically drunk during celebrations. For example British Prime Minister Tony Blair held a Champagne reception to celebrate London winning the right to host the 2012 Summer Olympics. It is also used to launch ships when a bottle is smashed over the hull during the ship’s launch. If the bottle fails to break this is often thought to be bad luck. Most of the Champagne produced today is « Non-vintage », meaning that it is a blended product of grapes from multiple vintages. Most of the base will be from a single year vintage with producers blending anywhere from 10–15% (even as high as 40%) of wine from older vintages. If the conditions of a particular vintage are favourable, some producers will make a « Vintage » wine that must be composed of at least 85% of the grapes from vintage year.Button Under Champagne wine regulations, houses that make both vintage and non-vintage wines are allowed to use no more than 80% of the total vintage’s harvest for the production of vintage Champagne. This allows at least 20% of the harvest from each vintage to be reserved for use in non-vintage Champagne. This ensures a consistent style that consumers can expect from non-vintage Champagne that does not alter too radically depending on the quality of the vintage. In less than ideal vintages, some producers will produce a wine from only that single vintage and still label it as non-vintage rather than as « vintage » since the wine will be of lesser quality and the producers have little desire to reserve the wine for future blending.
