This week on Grain of Salt, Donnie is talking to local urban farmer Robbie Gianadda. Over the last two plus year, Robbie has been growing some of the area’s best mushrooms out of his Elmwood Avenue home. What started as a fun hobby with spent grains from SPoT Coffee has turned into a full time production facility, pumping out nearly 100 lbs of mushrooms a week to the best local restaurants in the area. Learn about the health benefits of mushrooms, his plans for the future and more.
