This is great. I was searching for a slightly more sweet Manhattan. This does a great job of having a bit of sweetness, while the additional bitters and surprising bit of dry vermouth prevented it from being too cloying.
Terrific! Enough rum that I could enjoy the funky nose using Havana Club Añejo Clásico. The rum, citrus and other flavors were in perfect balance. Nice upgrade in complexity from a standard daiquiri.
