Walnut bitters is a cocktail bitters whose defining flavor is walnut, used in small dashes for a nutty accent.
ABV High in the bottle, but negligible in dashes — makers differ too widely for a single figure.
Nut bitterness at dash strength — a small family, and the bottles inside it change the nut rather than the role.
Sugar and volume come attached to the same nutty-bitter note. It is a pour rather than a dash, so it changes the balance of the drink and not just its seasoning. The drink’s sweetener needs recalculating, and dashes become milliliters.
Another nut bitters
Dash for dash they stand in for each other; walnut, pecan and hazelnut differ in the nut and not in the bitterness.
Walnut extract keeps well in alcohol; the oil that would go rancid in a kitchen is not present in a bitters bottle in any quantity. Expect a slow deepening of color and no meaningful loss of character.
