The Jewett & Sherman Merchants’ Mills building is one of the oldest buildings in Milwaukee’s Historic Third Ward. The building was constructed in 1875. The building was restored in 1979. It is a part of the historic “Commission Row” that is central to the Third Ward’s identity.

Jewett and Sherman was once a prominent manufacturer of coffee and spices.

The building was renamed the Product Exchange Building for a portion of its existence. In 1977, it was purchased and extensive remodeling was done before a five-alarm in 1979. Restoration began again after the fire.

The building is often incorrectly referred to as the Merchant Mills Building. A report from 1892 and another from 1896 reference it as The Merchants’ Mills, of the Jewett & Sherman Co. The name is derived from the company’s Merchants Coffee and Spice Mills located at the site.

In early 2014, Colectivo Coffee opened in the form Third Ward Caffe space.
