Although only half measures of each spirit are used, there are seven layers of them, so this is quite a potent cocktail. It is probably fortunate that after getting your tongue around a couple, you hand will become too unsteady to pour more.
½ measure green Chartreuse, chilled
½ measure triple sec, chilled
½ measure cherry brandy, chilled
½ measure crème violette, chilled
½ measure yellow chartreuse, chilled
½ measure blue Curacao, chilled
½ measure brandy, chilled
1. Pour the green Chartreuse into a chilled champagne flute, then, with a steady hand, gently pour in the triple sec to make a second layer.
2. Gently add the cherry brandy to make a third layer, the crème violette to make the fourth, the yellow Chartreuse to make the fifth and then Curacao to make the sixth.
3. Finally, float the brandy on top.
