Yeah, looks like it's contract brewed in several places around the world...
DUFF Sales & Marketing E.K. | Gotha, Germany
J.J. Bitting Brewing Company | Woodbridge, New Jersey
Brouwerij Haacht NV | Boortmeerbeek, Belgium
Simpson's Brewing Company, S.A. De R.L. De C.V | Zapopan (Jalisco), Mexico
...maybe the company contracting this out has rights to use the trademark?
