Steve Ury is an attorney by day and Recent Eats blogger by night who is tracking where the good stuff comes from. He tells All Things Considered's Audie Cornish that over 50 different brands from different companies appear to be bottling whiskey from this big Indiana factory, which goes by the name of MGP — Midwest Grain Products.

Ury says that one of the tell-tale signs on the bottle is the wording. "Does it say it is 'distilled' by that company, or does it say it's 'bottled by' or 'produced by' that company? That sounds like a small difference, but it has a big legal meaning."

He also looks for the recipe because the Indiana distillery uses 95 percent rye, which is very distinct. That's a red flag that it might be from Indiana.
