"It's an honor to be leading the rebirth of Rosen rye on S. Manitou Island, 100 years after it was first planted there. This project has sparked an exciting collaboration that will allow us to create world-class spirits using the grains, climate and distilling techniques of Northern Michigan."

—Chad Munger, Founder

The Rebirth of Rosen Rye

at the Hutzler Farm on South Manitou Island

The Story of Mammoth Rosen Rye

We spent some time with our friends at Whiskeyland, who produced this great episode documenting our Rosen Rye story. Continue to follow them for more great Rosen Rye storytelling!

With a permit from the National Park Service (MWRSLBE2501075), Mammoth Distilling is—for the first time in 70 years—growing pure Rosen rye on South Manitou Island. The histories of prize-winning Rosen rye, South Manitou Island and the Prohibition-era whiskey trade are inextricably linked. The reintroduction of Rosen rye to the Hutzler Farm, where it was originally planted 100 years ago, will allow Mammoth Distilling to revive a varietal of rye celebrated by legal whiskey makers and moonshiners alike for its distinctive and superior flavor.

Michigan’s role as the entry point for three-quarters of the liquor smuggled into the U.S. during Prohibition is well documented; less so is the state’s contribution to domestic whiskey production during that period. As the sole-source of Prohibition's most celebrated whiskey grain, recognition of the South Manitou Island's contribution to American whiskey is overdue.

The seeds we planted there were obtained from the USDA seed bank in Colorado, propagated by the Michigan State University Bio Agriculture Research Center and certified by the Michigan Crop Improvement Association. As our South Manitou Island site expands, certified Rosen rye seed will be distributed to partner farms across Michigan and grown under contract for distillation of Mammoth's Northern Rye Whiskey.

Certified Rosen rye seeds were obtained from the USDA seed bank in Colorado and propagated by the MSU Bio Agriculture Research Center.

This initial harvest yielded enough seeds to plant a foundation crop at Hutzler Farm on South Manitou Island.

On 8 October 2020, the Mammoth Distilling team worked the land at Hutzler Farm for the first time in 70 years.

This foundation crop of Rosen rye will yield enough new seed to plant more than an acre of additional certified Rosen rye in 2021.
