Southern Comfort

Southern Comfort is an American, fruit flavoured whiskey liqueur. Originally created by bartender Martin Wilkes Heron in New Orleans in 1874, the brand has gone through closure during the Prohibitions and transitions and transfer of ownership.

Spirit Historian Chris Morris describes the original recipe of Southern Comfort in an episode of The Thirsty Traveler titled "A River of Whiskey"

Heron began with good-quality bourbon and would add: An inch [2.5 cm] of vanilla bean, about a quarter of a lemon, half of a cinnamon stick, four cloves, a few cherries, and an orange bit or two. He would let this soak for days. And right when he was ready to finish, he would add his sweetener: he liked to use honey. - Wikipedia

In the United States, Southern Comfort is available as 42 US proof (21% ABV), 70 US proof (35% ABV), 100 US proof (50% ABV), and 60 US proof (30% ABV) in Australia. Varieties including additional flavorings, such as lime and caramel, were introduced by Brown–Forman in the latter years of their ownership. These were discontinued by Sazerac - Wikipedia
