Rural Stearns County was a hotbed of moonshine-making during Prohibition, and the prime product was "Minnesota 13" whiskey. In the documentary "Minnesota 13: From Grain to Glass" (⋆⋆⋆ out of four stars) directors Kelly Nathe and Norah Shapiro do an excellent job of sourcing this colorful but covered-up history, coaxing tales from old-timers who were youngsters then and giving insight into why the staunchly German Catholic culture found the practice — the only way to make a living when crop prices bottomed out — "illegal but not immoral." The final segment illustrating how Minnesota 13 is back in legit production gives a full-circle feeling to a clandestine chapter of Minnesota history. Original guitar-pickin' music by John Fields sets a perfect tone.
