I like the idea of this, but it left me a little perplexed... Not sure if I stirred a little too long, or if it's just normally a little thin/weak? I guess I expected more from the rum (used Goslings Black Seal). Might try it again with 20 ml of vermouth or something?
Being really big rum drinkers (we have over 25 different rums), we loved this. Used a combination of Jamaican and Barbados black rums. As I suspected, the mixture of the two rums were perfect for our tastes. It needed a little of the Jamaican funk to add the punch of flavour.
The other day I noticed the other day that an addition of orange bitters to a gold rumhattan mellowed it out - too much. Today I tried a black rumhattan with the addition of Regan's orange bitters, hoping it's more to my taste.
40 ml Goslings Black Seal, 20 ml Dolin Rouge, 1 dash Angostura, 1 dash Regans Orange bitters. After a few tastes I decided it needed some sweetness, so I added 1/2 a tsp (2.5 ml) of luxardo syrup to the drink. Tasty.
Made this with Bacardi Ocho and M&R Rosso, with and without Angostura. Without Angostura it's a discordant disappointment. With angostura, it's a harmonious whole.
I skipped trying it with a dark rum even though I have Goslings Black Seal on hand - I just don't expect it to work well. I might try it some other day.
Ran out of M&R Rosso and got a bottle of Dolin Rouge. Decided it was a good time to do a side-by-side of gold vs black.
40 bacardi ocho + 20 dolin rouge + 1 dash angostura - still damn tasty.
40 gosling black seal + 20 dolin rouge + 1 dash angostura - I don't really feel like the molasses and spice fit in this drink. There might be something that could done about that, but as it stands I much prefer this drink with gold rum.
The idea of a rum Manhattan intrigues me; I feel like this would be best with a rum with a decent amount of character to it, something like Myers's or a straight up aged rum - perhaps with the addition of a flamed orange twist (discarded if need be), possibly also a pinch of overproof rum to add further flavor on top of the vermouth and bitters? There *could* easily be a five star drink in here I feel, if given a little more zhoozh.
