Rosemary's Baby, from the previous post, reminded me of this one. Both have rosemary and fire. This one looks like a Last Word riff on paper. And I suppose it has too much in common to argue the point but the adjustment of quantities (here 2 oz gin and 1/2 oz of the rest as opposed to everything equal parts) along with the rosemary help this thing carve out its own territory.
The Rubicon comes from Jamie Boudreau and he has a great post here detailing the creation of the drink, the effect heat (here it's fire) can have on ingredients, etc. He also explains how the name of the drink was inspired by the resemblance the rosemary has to the crown of laurels associated with Julius Caesar. When Caesar led his troops across the river Rubicon to Rome it was in defiance of Roman law. A civil war followed, Caesar became dictator and the unrest following his eventual assassination led to the transition of Rome from a Republic to an Empire. Before crossing it he stated 'The die has been cast!' (although he probably said it in Latin) and 'crossing the Rubicon' has come to mean 'a point of no return'.
Enough history (which I probably screwed up anyway), this drink is great and it's fun to make for people.
The scent of rosemary opens things up. Beneath that, on the sip you have a deliciously herbal gin sour. Chartreuse and maraschino do their thing. The former bringing herbs and some heat while the latter contributes its unusual sweet and nutty quality with hints of fruit. Both are tempered by the lemon which allows the gin and rosemary to stand in the center. The finish finds everything balanced and blending together nicely.
