Root Beer Bitters

Root beer bitters are cocktail bitters built on classic root-beer botanicals — sassafras/sarsaparilla root, wintergreen, birch bark, anise, licorice, vanilla, and warm baking spices (cinnamon, allspice) — typically with a whiskey or rum base. They contribute a nostalgic, earthy, sweet-spiced aromatic profile to whiskey, rum, and dessert-style cocktails. A few dashes evoke the rooty, soda-fountain character of old-fashioned root beer without the sugar.
