Hand-peeled, hand-cut Vietnamese ginger is the core of this spicy, exotic elixir. It is then macerated with herbs and spices and married with a fine Cognac. "Ginger," according to the New York Times, "as a cocktail ingredient, is on a serious roll right now… but the Domaine de Canton, which fuses baby ginger with Cognac, feels more like a classic than something parachuted into a trend. It's got that ginger heat, but it's not too strong and it's very aromatic. It's also a lively addition to Champagne."
