great and refreshing sipper, but I do agree with Matt: next time I will reduce the mint liqueur a bit.

For me - the creme de menthe is to heavy handed and one-dimensional (vs. the Toronto, for example, where fernet brings something beside freshness). I'll need to try vs. the Midnight Stinger to see what I think. I've also had a rye and fernet variant on Negroni/Boulevardier called a Northern Standard that again, I think works better than creme de menthe here.

This is outstanding. A perfect after-dinner cocktail. Hints of mint and chocolate. The bourbon shines through all the flavors.
