A Jeroboam is a large wine bottle that typically holds 3 liters of wine, equivalent to four standard 750-milliliter bottles. It is often used for sparkling wines, such as Champagne, and is named after the biblical figure Jeroboam, who was the first king of the northern kingdom of Israel. The size is popular for celebrations and special occasions due to its impressive appearance. In the world of wine, Jeroboams are part of a series of large-format bottles, which also include sizes like Magnum (1.5 liters) and Methuselah (6 liters). These larger bottles are believed to enhance the aging process of the wine, allowing it to develop more complex flavors over time.
