The Navy Grog is made of White Rum, Demerara Rum, Black Rum, Lime Juice, White Grapefruit Juice, Honey Syrup, and Club Soda. It is named after the British Royal Navy, who were known for their love of rum. Navy Grog has a strong rum flavor with a hint of sweetness from the honey syrup. The lime juice gives it a tartness, while the grapefruit juice adds a bit of bitterness. The club soda helps to balance out the flavors and make the drink refreshing. The history of Navy Grog is closely tied to the history of rum. Rum was first produced in the Caribbean in the 1600s and was soon exported to Europe, where it became very popular. The British Royal Navy started giving their sailors a ration of rum in the 1700s, and it quickly became known as ""Navy Grog."" The recipe for Navy Grog has changed over the years, but it remains a popular drink among rum lovers.
