As Peter Konkoly, this cocktail's creator says, it is reminiscent of a Last Word. However, we prefer this tasty drink served on-the-rocks as an aperitif...
Like others below, I cut the Suze to 3/4. I also increased the kirsch to 1 1/4 and replaced the sugar rim with 1/3 simple syrup (you really need the bit of extra sweetness, I think). All in all an excellent drink, leading off with mild cherry before transitioning to herbal notes, and finishing off with mild gentian bitterness.
I never comment but this is absolutely phenomenal. Admittedly I can't taste the Kirsch but my bottle of G. Miclo has been open a long time. This is no bad thing however, as when it was fresh I really didn't like it! Don't know why but I prefer a great many cocktails on the rocks (like here) rather than up.
