The Milwaukee Brewers farm system consists of seven Minor League Baseball affiliates across the United States and in the Dominican Republic.
The longest continuous affiliation in team history was the 23-year relationship with the Class A Beloit Brewers/Snappers of the Midwest League from 1982 to 2004.
Geographically, Milwaukee's closest domestic affiliate is the Wisconsin Timber Rattlers, which are approximately 90 miles (140 km) away.
