Rivella is a soft drink from Switzerland, created by Robert Barth in 1952, which is produced from milk whey, and therefore includes ingredients such as lactose, lactic acid and minerals.

In 1950 Roberth Barth and the biologist Hans Süsli Zurich used a recipe initially conceived to produce a beer made with whey to create a soft drink, which came to be marketed as Rivella Red in 1952, when Rivella AG was founded.

[1] The name Rivella was inspired by the municipality of Riva San Vitale in Canton Ticino and the Italian word for "revelation", rivelazione.

In 2008, Migros replaced it with Rivella as it did not enjoy the same popularity among customers as the original drink.

[6] In February 2022, in a further attempt to compete with Rivella, Migros revived the competitor drink "Prego",[7] which dates back to 1956 when it was created by Robert Schlör.
