Rivella, a popular Swiss soft drink, was created in 1952 by Dr. Robert Barth, a Swiss food scientist, who sought to repurpose whey, a byproduct of cheese production. Experimentations led to a formula combining whey with herbs, fruit extracts, and other natural ingredients, resulting in Rivella’s distinct flavor profile. Initially met with skepticism, Rivella gained popularity for its unique taste and perceived health benefits, becoming one of Switzerland’s most beloved beverages. Today, Rivella continues to thrive with various versions, including classic, light, sugar-free versions and even a vegan option.
