Malt vs Milkshake Debunked: Is There Really a Nutritional or Taste Difference?
By Robert Thorne
The malt shake did not start as a nostalgic treat. It was formulated in an 1870s laboratory in Racine, Wisconsin. English-born pharmacist William Horlick and his brother James set out to manufacture an easily digestible infant food for children who could not tolerate fresh cow's milk. Fresh milk at the time spoiled quickly and often harbored dangerous bacteria before municipal refrigeration and strict pasteurization took hold.
Horlick combined sprouted barley malt extract with wheat flour and whole milk solids, drying the slurry into a stable, non-perishable powder patented in 1883 as "Diastoid." The key biochemical mechanism rested on barley's native digestive enzyme profile, particularly alpha-amylase and beta-amylase. These enzymes split complex starches into maltose, a disaccharide sugar that broken down rapidly in the human gut. The powder proved so nutrient-dense and shelf-stable that polar explorers like Roald Amundsen and Richard E. Byrd carried thousands of pounds of Horlick's malt on Arctic expeditions.
The pivot from medicine to indulgence occurred in 1922 at a Chicago Walgreens counter. Fountain clerk Ivar "Pop" Coulson ignored standard operating procedure by scooping two generous balls of vanilla ice cream into the store's warm malted milk drink. The resulting frosty glass became an immediate commercial juggernaut, establishing a durable soda fountain tradition that spread across drugstores and drive-ins nationwide.
