And it's DIFFERENT in that the gravity is MUCH denser than most other alcohol
floats & layers, so you can safely let it flow through the rest and settle in
the bottom, no argument. Most other mixes need to go bottom-up as they'd mix
too much on the way through. You could (I guess) make a black russian shot by
layering the kahlua in and under vodka if you wanted, but only because Kahlua
is SIGNIFICANTLY heavier than vodka.
It cannot be built, as pouring a large volume of thin liquid into a tall glass
is pretty much guaranteed to stir up whatever you have sitting at the bottom.
Variety is good. The Tequlia sunrise is reasonably unique in this little
method (See also Shirley Temple)
