The Milwaukee-area company Northwestern Extract is playing a behind-the-scenes but also vital role in the flavor of Wisconsin beverages – as well as products made by companies around the country. Bill Peter is President of Northwestern Extract, the flavoring company his grandfather started in Milwaukee almost a hundred years ago. The company just left Brookfield and moved into a new facility in Germantown. We spoke with the company as part of our Project Milwaukee: What's on Our Plate? series.
