Southern Comfort Liqueur is called variably a flavored whiskey or a liqueur, often depending upon the proof, which can come from 100 all the way down to 40. We have opted to list it at 70 proof as the most common spirit available in the United States and a liqueur rather than a flavored whiskey due to its sweetness and dramatic flavors. Southern Comfort is the oldest whiskey liqueur available on the market flavored with peaches and other citrus flavors. As a sweeter, softer product it has become popular in numerous mixed drinks. It was originally produced in 1850 by Irish-born M.W. Heron in New Orleans. His original intent was to make rougher whiskeys coming down river from Tennessee and Kentucky more palatable. He did this by flavoring it with fruit and other flavorings--the birth of "Soco." Southern Comfort Lime was just released in May 2010. The folks at Brown-Forman decided that they'd do the mixing work for us.
