Thought I'd weigh in on a couple of jigger points: Beans is right about the physical device, the jigger - and, as such, it comes in various sizes. A jigger is also a somewhat variable UNIT of bartending measure - much like a Tot. The jigger unit has been pretty much standardized at 1.5 oz, but older bar books have ref'd a 1.25 oz jigger - and sometimes (depending on the book, locale, and era) a 2 oz jigger. The use of the term as a unit is old fashioned too, but continues to this day (having dropped off since the 70s). The earliest citations actually called it a gigger. In those days other measures were equally perplexing: the wineglass (2 oz) and of course the pony (1 oz). Actually, the wineglass makes more sense than you'd think: while in the 19th century they certainly had 4 oz wine glasses, what was meant by the measure was a sherry glass - to this day, with a 2 oz volume. I apologize for swinging farther afield from South Carolina. I'll add this to that: I also caught the NPR piece. Most bars serve a 1.25 oz measure? Not the bars I go to. That's a very light pour in my experience. --Doc.
