Released in 2005, Regans’ Orange Bitters No. 6 was the first commercial bitters of the modern-day bitters boom. Before Regans’, it had been 50 years since the last bitters were introduced by Fee Brothers.

Self described “cocktail freaks” Gary and Mardee Regan began work on their orange bitters in the late 1990s. After considerable research of the out-of-print 1939 book The Gentleman’s Companion, and many other trials and tribulations, a modern-day classic was born, and the “bitters boom” officially kicked off with Regans’. Whether it will be your favorite orange bitters or not, it’s certainly hard to beat for the price.
