Precoating Enzinger Memo at Schmidt Brewery

G. Heileman Brewing Co., Inc. took over the Jacob Schmidt Brewing Company's St. Paul plant in 1972, continuing beer production there under the Schmidt name for nearly two more decades. This interoffice memorandum, dated March 23, 1990, is addressed from M. McDonough to the brewery's staff and outlines a step-by-step procedure for precoating an Enzinger filter, a rotary vacuum filter used to clarify beer before it was packaged. Heileman halted brewing at the West Seventh Street complex later that year, after which Minnesota Brewing Company took over the site. The Schmidt Brewery complex, parts of which date to 1900, is listed on the National Register of Historic Places.
