The story
Double Rainbow was originally founded by Michael Sachar and Steven Fink, two childhood friends from Brooklyn. As kids, they would sell frozen popsicles on the beaches of Coney Island, with the dream of one day opening their own ice cream parlor. On September 28, 1976, they signed their first lease for their first ice cream shop on Castro Street. On that same day, a double rainbow lit up the San Francisco sky, and the name was born.
In 1982, Double Rainbow won the top prize in the "Great American Lick-Off."
The company offers more than 60 flavors in pint, quart, and 2.5 gallon tubs. Seasonal flavors include Pumpkin, Peppermint Cookie Crunch, Eggnog.
Manufacturing took place in the heart of San Francisco's mission district for over 40 years. In 2019, manufacturing re-located to Emeryville, CA.
