The Iowa Distilling Company Small-Batch Process

Local Ingredients, Hand Distilled in Ridiculously Small Batches

Most American whiskey is made in factories humming with computer-controlled machinery. That method certainly makes a lot of whiskey in a hurry…but that is not our method.

augerOur process starts when we visit our local farmers’ coop to purchase Iowa corn. It is the best corn on the planet, grown by farmers who know a thing or two about growing corn. We bring the corn back to our distillery in Cumming, Iowa, where we grind it into flour.

After we distill our whiskey, we distill it again, at least one more time. This second distillation makes a smooth whiskey even smoother. Finally, we add pure water to reduce the whiskey’s final proof before bottling.
