Regan's - Orange Bitters - No 6

Regans' Orange Bitters No. 6 is a classic American cocktail bitters, concentrated orange peel and spice suspended in high-proof spirit at 45% ABV. It is a bar-cart staple rather than a drink in its own right, made to season cocktails a few dashes at a time.

Keep a bottle behind the bar for Old Fashioneds, Martinis and other spirit-forward classics, where a touch of bitter orange rounds out the sweetness and lifts the aromatics. A small addition that changes the whole drink.
