The Siebel Institute of Technology is a technical school located in the Lincoln Park neighbourhood of Chicago that focuses on brewing science. The school is the oldest brewing school located in the United States and has been in operation since 1872. During Prohibition, the institute diversified by adding courses in baking, refrigeration, engineering, milling, carbonated beverages and related topics. After the repeal of Prohibition, courses not concerned with brewing were discontinued. There are satellite campuses in Munich, Germany and Montreal, Canada.
