The old Fermenting or Lagering House is probably my favorite building at the Lemp Brewery, with its three original floors above ground, and the same depth below ground as it is tall. There are two ugly additional floors added by the International Shoe Company, as well as rectangular windows punched in the façade of the original building.
Triple pane windows of the original fenestration allowed light in, but kept frigid temperatures in as well. It’s an impressive building that originally faced Second Carondelet Avenue, hence the elaborate decoration with quoining and pilasters in brick. It was designed by Theodore Krausch, a pioneer in artificial refrigeration, which you can read about here.
