Place one large ice cube in a rocks glass.

Pour the non-alcoholic gin alternative, the sweet vermouth alternative, and the bitter aperitif over the ice in equal one-ounce pours.

Stir the drink slowly with a bar spoon for 20 seconds, until the outside of the glass turns cold and slightly frosted.

Cut a two-inch strip of orange peel with a vegetable peeler, avoiding the white pith.

Hold the peel over the glass, orange side down, and pinch it to release a fine mist of citrus oil across the surface.

Rub the peel around the rim once, then drop it in.
