I’m not certain, though I have been to the Laverne and Shirley temple in Sprecher Brewery, but:

Hassenpfeffer sounds like a play on Harnischfegger, a maker of heavy construction equipment in Milwaukee.

Trivia: One of Henry Harnischfeger’s customers was Pabst Brewing Co.

Harnischfeger ran itself into the ground in the 90s. I worked in their headquarters for more than a decade. That building is prime real estate and became an FBI office.
