About Jupiter Ridge LLC

Jupiter Ridge Farm (Jupiter Ridge LLC) produces ethically and sustainably grown gourmet shiitake mushrooms, herbs, and vegetables in Garber, Iowa, between Elkader and Guttenberg. The farm is located atop a 1200-foot high ridge covered with prairie and forest, nestled deep in the bluffs of Driftless Iowa (Northeastern Iowa). Farmer William Lorentzen, along with co-farmer, co-owner, and freelance sustainable agriculture and herbalist writer Adrian White, combine their farming fortes into a happy and sustainable whole.

In the past, both Will and Adrian managed Echollective Farm & CSA (Will for 6 years, Adrian for 3) in Mechanicsville, an organic farm just north of Iowa City, Iowa. During that time, Will began his own growing initiative specializing in organic shiitake and oyster mushrooms in 2012, along with an ethical Swine CSA that ran for 3 years. A land opportunity with the Sustainable Iowa Land Trust (SILT) brought the farm up to northeastern Iowa in late 2016, finally starting its own independent operation on independent land.

Shiitake mushrooms are grown organically on hardwood logs that are ethically and locally sourced. Vegetables are produced using sustainable and environmentally responsible growing methods, including healthy soil building, cover cropping, crop rotation, compost amending, all-natural fertilizers, and minimal chemical use (save for pesticides allowed in USDA organic certification). We are working towards both USDA Organic Certification and Certified Naturally Grown labels.
