I usually like my drinks on the dry side, but for this one I think a sweeter formulation would work better. Will have to experiment.

The coffee liqueur and creole bitters surprisingly play well with the blackberry liqueur. Great for fans of unusual flavour combinations.

Very nice, the gentian comes through clearly and the Chartreuse adds some nice background complexity. I am thinking of trying it with some thyme liqueur to contribute to the colour and theme of the drink.

Quite good with white (sweet) vermouth as well. It emphasizes the botanicals nicely, though it may not be as visually appealing.
