In a broadcast that originally aired on The Food Garden Life Radio Show, we chat with Jude Schuenemeyer from Colorado about the history of apple cultivation in Colorado, his work finding and preserving heritage apple varieties—and the recent “rediscovery” an a variety that he and his wife Addie have been working to track down and identify for 20 years: the Colorado Orange.

Schuenemeyer, a Sherlock Holmes of the apple world, scours historical horticultural records and talks to old timers, as well as using technology such as genetic fingerprinting.
