Hi Kim,
Well, I guess everything's bigger in Texas. But that's a genuine California bar-size wineglass. I'm serious, my wife does bookkeeping and accounting for a local pub, We bought a bunch of those glasses from her client. They're designed to prevent overpouring by the bartenders, but they're not all that small. You can fill four of them from a 750 ml. bottle. They're hard to find, except through restaurant and bar supply places. Take a whack out of the jug, squint, and look again. It'll look more the right size that way!
