Probstfield family diary entries mention that Randolph stopped by John Erickson’s brewery from time to time on trips into Moorhead. He bought Erickson’s beer and he also bought hops, which indicates German-born Randolph did some homebrewing. One of Randolph’s oldest and closest friends from the pioneer days, Nick Hoffman, owned a brewery in East Grand Forks. Randolph’s son Andy worked at Hoffman’s brewery. According to family letters, Randolph eagerly awaited Andy’s gifts of Bock beer in the spring.
