It's all but forgotten nowadays that "Applejack" was once used to refer to hard cider. The "Jack" part referring to "Jacking", an obsolete method of cold-air distilling, essentially leaving cider out in the cold in a barrel to ferment and periodically removing the ice that formed, thus increasing the alcohol content by removing the water. This method was fairly inefficient and the end product didn't taste all that good, and as soon as proper stills were available people quickly abandoned it for better liquors.
That's right, they named the character of an animated cartoon after a kind of booze..... bad-made booze in fact.
