Southern drinks tend to be sweet, or sour, or sweet and sour. After all, citrus fruits and sugar cane both grow in southern climes. And Southern manners (at least according to stereotype) consist of both sweet hospitality ("Honey, chile!") and sour hostility ("Damn yankees!") in more or less equal parts. Southern Comfort is a "whiskey-flavored liqueur" containing honey and lemon and can be used in the making of a whiskey sour. The beverage dates from its earliest manufacture in 1874 and is said to have its origins in New Orleans. It also won the gold medal at the 1904 World's Fair in St. Louis, Missouri. Southern Comfort now produces "ready to pour cocktails," such as Sweet Tea, Hurricane, and Lemonade—with Southern Comfort Lime primed to debut this summer. Today's typo unites both North and South, giving rise to Sourth*, which appears 22 times in OhioLINK.
