What is the name of the cocktail with the greatest number of layers in a layered drink and which order are the various liqueurs poured? Could anyone tell me what is the name of the cocktail with largest number of layers in a layered drink and in which order the various liqueurs are poured into it?


  A layered (or "stacked") drink, sometimes called a pousse-café, is a kind of cocktail in which the slightly different densities of various liqueurs are used to create an array of colored layers, typically two to seven. - Wikipedia.
The most layers I have seen (and drunk) is the Pousse Cafe No. 1 - with 6 layers.



It has equal measures of 6 liqueurs and spirits:


Grenadine
Maraschino
Creme De Menthe
Creme De Violette
Yellow Chartreuse
Brandy


Pouring uses the usual layer process - pour down the back of a spoon...very gently, so you don't mix with the previous layer.
