ST. JOSEPH — Gregg Obbink spent much of his career working on spacecraft at one of the nation's top research and development laboratories.
After retiring 15 years ago, he moved back to Minnesota and picked up some hobbies like fishing, bird hunting and sampling bourbons.
Obbink, now 67, started to wonder if he could make his own spirits — with sips that were smoother and more flavorful than the ones bottled at gargantuan commercial distilleries.
"I figured if someone else can make it, then I can, too," he said.
But traditional whiskeys are aged for at least two years, with some high-end whiskeys aged for decades. And Obbink didn't want to wait.
"I realized right away that this was going to take way too long to do it the way everybody else did," he said. "So I figured out a way to do it more expeditiously."
Using the same ingenuity that helped put a rover on Mars, Obbink discovered a way to create "aged" whiskey in about 30 days, using a proprietary process with equipment he built. Now, he's letting patrons sample his creations at a new distillery in St. Joseph, which is about 75 miles northwest of the Twin Cities.
Whiskey begins with a mix of grains such as corn, wheat or rye that is heated and fermented into a mash. The liquid is then distilled in copper stills, where the alcohol is heated to a vapor and then cooled. This separates the liquid from solids and unwanted substances, and increases the alcohol content as the water evaporates.
