Grog is a term used to describe a mixed drink that typically consists of rum diluted with water, often sweetened with sugar and flavored with lime or lemon juice. It originated in the British Navy during the 18th century as a way to make the rum more palatable and to prevent sailors from becoming too intoxicated. The drink was named after Admiral Edward Vernon, who ordered the dilution of rum with water. Over time, grog has evolved to include various recipes and ingredients, sometimes incorporating spices or other spirits. It is often associated with pirate culture and maritime traditions, making it a popular choice in themed bars and events. Today, grog can be enjoyed in many forms, reflecting its rich history and adaptability.
