A delicious martini-like concoction; we get a forward, almost limoncello-like sweetness, quickly followed by a complex herbalness with fennel to the fore. We used celery bitters as that's what we had in. Overall a well-rounded, full-spectrum herbal drink.
Somehow this manages to be both mellow and zingy at once, and dangerously drinkable. The rose came across mostly in the nose for us, although it does also soften the herbal notes from the chartreuse. Overall a treat!
Absolutely delicious. Agree with earlier commenters' positivity. We used Amaro Lucano and 4 dashes of Fee Bros grapefruit bitters. Very complex; flashes of a Manhattan but with extra smoky depth and florally-enhanced Amaro.
