The French 75 cocktail is a classic drink that originated in Paris in the early 20th century. It's named after the French 75mm field gun, which was used by the French army during World War I. The drink is said to have been created at the famous Harry's New York Bar in Paris, and it quickly became a favorite among American expatriates and Parisians alike.

Today, the French 75 cocktail remains a popular drink in cocktail bars around the world. It's a refreshing and sophisticated drink that combines gin, lemon juice, simple syrup, and Champagne.

In French cocktail culture, the French 75 is often served as an apéritif, which is a pre-dinner drink meant to stimulate the appetite. The French take their cocktail culture seriously, and there are many famous bars and bartenders in France that have helped shape the cocktail world. The French are also known for their love of champagne, which is often used as a key ingredient in cocktails like the French 75.
