Although far lesser known abroad than in Switzerland, and therefore not as generally associated with “Swissness” as, say, Toblerone chocolate or Gruyère cheese, Rivella is nevertheless a Swiss invention. Not only was it invented in Switzerland by a Swiss, but it also contains about 35 percent of milk whey, so we can only assume that (Swiss) cows were also involved in its production. "Swiss people, on the other hand, grow up with Rivella; they are almost as familiar with it as breast milk."
