Today, there are five main styles of gin produced, most of which originated in England. London Dry is by far the most popular style of gin made globally, while other well known gin styles include Old Tom, Plymouth, Navy Strength and Flavored gin. Even though all gins are flavored with botanicals, Flavored gin, like Flavored vodka, features a dominant flavor of the flavoring agent, such as grapefruit, cucumber, or ginger.
