The liqueur is made using the petals of Sambucus nigra from the Savoie region in France, and each bottle is numbered with the year the petals were collected). St-Germain was created by Robert Cooper, the son of Chambord inventor Norton “Sky” Cooper, after trying an elderflower-based cocktail at a London bar in 2001). The brand was named after Saint-Germain-des-Prés, and the bottle shape is influenced by Art Deco motifs associated with the Belle Époque history of this area). St-Germain was launched in 2007 by Cooper Spirits Co, a company founded in 2006 and headquartered in New York). In 2013, the company was sold to Bacardi, and Robert Cooper agreed to work with Bacardi as a "brand guardian" and spokesperson).
