A nice cocktail, as said easy to sip. Rum and Chartreuse is a new combination for me which works very well. But only because green Chartreuse is used and it has a cherry garnish it is IMHO no real Last Wort riff.
A definitely different riff on the Last Word. All the botanical comes from the chartreuse alone with rum replacing the gin, but that's not a bad thing. It lets the chartreuse shine on its own. The sweetened lemon is a little milder than the lime and maraschino and sits nicely with the rest of the drink.
A notch below the Last Word, but for me that just means I'm giving it 5 vs 5+ stars!
Light and fresh. Very easy to sip. The Chartreuse gives a gentle herbal undertone to what would otherwise be a simple daiquiri. Not complex, but very enjoyable.
