Delicious! Sweet and velvety, but not cloying. Based on Simon Sedgley's suggestion, I may try substituting Hogsworth (a craft blend of bourbons and aged armagnacs marketed here in the US) for the armagnac the next time I mix one. Will add another comment if I do.
Very elegant and luxurious. As a bolder alternative, we think Rittenhouse Rye works very nicely as a substitute for the Armagnac...one might even add a further dash of bitters.
Very good, a very interesting way to show up the black walnut bitters ( they are a recent acquisition of mine and I'm in ove with them). Made it with Torres 20 Hors d'Age brandy. Catalan brandies have a nice vanilla touch
