History

Ledgerock Distillery is a family-owned distillery located on the Retzer Farm in Wisconsin. The distillery opened in 2018, and on the 500-acre farm the Retzer family grows, harvests, stores, mills, distills, bottles, and brands the grain. They plant the seeds and create the spirit – from seed to spirit. On the farm, yellow corn and soft red winter wheat are grown in a sustainable manner with minimum or no tillage to reduce water and wind erosion. This practice creates better soil structure, which provides better air and water filtration and higher quality grain. The entire process happens on the farm/distillery to create From Seed to Spirit.

Production / Manufacturing

Ledgerock Distillery sits on and operates the family's farm between Fond du Lac and Eden, Wisconsin. The distillery's name stems from the place – The Ledge – Niagara Escarpment, where ledgerock (limestone) helps filter the water supply and makes it ideal for the distillation process. We distill year-round using the grain we grow on the farm. Those who plant the grain are also the ones who distill, bottle, and brand our spirits. While you visit the distillery, you can see every step in the process – from the field to the production area, bottling, and storage facilities. We are open and distill year-round using the grain we grow on our farm. We welcome visitors Wednesday to Saturday 11:00–17:00. Tastings and cocktails are available every day, as are bottles for purchase.

Products and Production Philosophy

We produce a range of spirits based on grain from the farm: yellow corn and white winter wheat are grown sustainably, and the entire process takes place on the farm. The natural water source comes from ledgerock bedrock, which filters the water for the distillation.

Philosophy

Ledgerock Distillery is a family-owned farm business, where the entire process takes place on the same farm. The farm, the distillery, and all steps of production take place on the Retzer Farm under the From Seed to Spirit concept. The grain (yellow corn and soft red winter wheat) is grown sustainably with minimal or no tillage to prevent erosion and preserve soil structure. The water is filtered through ledgerock (limestone), providing a clean and suitable base for distillation. We grow, distill, bottle, and label our own spirits – a full farm-to-glass experience, with the family behind every step.
