They say it's the world's most refreshing margarita. We haven't tried every margarita on earth just yet (we are working on it) so we can't comment on that, but it sure does have a sweet, tingling kick. Cayman Jack Margarita is made from premium ingredients - such as organic limes, cane sugar and blue agave - and you sure can tell. Doesn't make the hangover any sweeter though.
