These famous German bitters, sold in brown paper wrapped miniature bottles, were first produced in 1846 by Herbert Underberg. Herbs and roots are hot macerated...
I love this stuff straight out of the bottle. Try it. While you're at it chase it with two or three dashes Regans' Orange Bitters right into your mouth preferably as the Underberg rests on your tounge. Liquid Sen Sen plus orange.
