If this is the case, I'm curious what the strategy is behind this.
To get a cheap beer and remove the stigma of the typical cheap beer brands by giving it a house brand name?
To get a much better price from on the entire product line from a macro-brewery due to more volume?
There are very few large-scale brewers any more. Beers like Schlitz, and Pabst which are recipes and brands owned by Pabst are actually contracted out to Miller to produce. City Brewery in Lacrosse does contract brewing too, in fact that's why they bought the old Latrobe Brewery in PA (Rolling Rock is now made at AB facilities because they bought the company, recipe and brand)
I would imagine that Kum & Go has a recipe and a price-point in mind and they are contracting the production out to a larger brewery (like Miller) for fulfillment. No place in Iowa has the capacity for that kind of volume yet.
