Upon difficulty finding orange bitters to suit his discernible palate, noted sprits reviewer, writer, and former bartender Gary “Gaz” Regan decided to make his own. After spending considerable time trying to come up with a suitable recipe, Gaz entered into a partnership with The Sazerac Company to create his beloved orange bitters. A team of Sazerac scientists worked on the project, and finally after much trial and error (5 other batches in fact) Regans’ Orange Bitters No. 6 was born.
