Rivella
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. Other than Switzerland, it is sold in several other countries, notably the Netherlands, and is available in several varieties depending on the country. 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. The name Rivella was inspired by the municipality of Riva San Vitale in Canton Ticino and the Italian word for "revelation", rivelazione. The initial production began in Stäfa before moving to Rothrist, where it remains to this day. Second variety of Rivella was launched in 1958 in the Netherlands and in 1959 in Switzerland, known as Rivella Blue, a lower calorie alternative to the original recipe. It was the first diet soft drink to be launched in Europe. A third variety, Rivella Green, was launched in 1999 made with green tea extract, and Rivella Yellow, made with soy milk as an alternative to milk whey, in 2008.[citation needed]
