Back in 2010, Boulder, Colorado-based Erik Knutson, with the help of family and friends, set his sights on creating a new way to experience the simple pleasure of enjoying a drink with friends: drinkable cannabis. Inspired by the notion of combining the fun, social, celebratory experience of drinking with the magic and joy of cannabis, Erik mixed up an early batch of “Keef Cola” and placed a prototype in front of his beloved Grandma Dee. (Because if an 85-year-old woman who’s never smoked cannabis in her life loves it, then they might just be onto something.) Dee opened the bottle and took a sip. And then another. That day, Keef was born.
