There's an interesting play between rum, vermouth and grapefruit which, with the right grapefruit, can be delicious. (Juice ripe pink or red grapefruit.)
I really enjoyed this one.
I was concerned that the quality of the ingredients could make or break the result, but my first attempt turned out great.
The funkiness of the rum (Havana Club 3 Añejo), the complexity of the vermouth (Carpano Classico), and the unexpected harmony with grapefruit created an impressive balance.
I can confirm that the quality of the grapefruit juice has a disproportionate influence on the overall experience (mine was definitely subpar). I also think a mid-range rum in terms of assertiveness is probably optimal. Mine was a bit too quiet and didn't register, but an overly funky spirit would throw this drink completely out of balance.
Indeed the grapefruit determines how the drink will turn out. I had what looked like an average Ruby Red Grapefruit. It resulted in some unusual, earthy tones, which wasn't too appealing, in my opinion. I do wonder if the sweet red vermouth contributes to that.
