How We Discovered the Fun and Excitement of The Big O®!

With our son heading off to college and Bill’s position at the university having been eliminated, Bill and Kath had to come up with a plan: too young to retire, too broke to survive, too old to get a job! So . . . we decided to combine business with pleasure; hence, the birth of Big O Ginger Liqueur®!  

Years before, we had created a ginger liqueur that balanced the cooling heat of ginger with a roundness and complexity given by other spices and ingredients. It quickly became a favorite among family and friends. At the urging of a friend, we decided to leap into the adventure and pursue our own American Dream. With no experience and precious little money, we started producing Big O® in small batches, using artisan-distilled spirits and the best all-natural ingredients.

We invite you to share the pleasure and passion we put into every bottle.

The Big O® – Discover your pleasure!
